I find it strange that all we hear about these days is the shortage of ventilators (okay, PPE too), as if it’s the only bottleneck. The reality is ventilators are useless without intensivists to operate them, and you need anesthesiologists and probably other skilled personnel too.
I learned through a personal connection who was actually on the ground in Hubei (but not Wuhan) caring for serious but non-ICU patients that doctors and nurses in their ward outnumbered patients, and they were at capacity. The staff-to-patient ratio should be higher in the ICU. With an overwhelming number of patients you simply can’t care for them, whether you have the machines or not.
It’s relatively easy to ramp up production of machines. It’s much harder to ramp up production of medical professionals.
> It’s much harder to ramp up production of medical professionals.
I have a mixed opinion on this. In particular, I don't think we really need to create more skilled medical professionals, we just need to change the way they work.
Most of doctors have exposure to the basics of intubating and ventilation through medical school. Those without direct critical care experience would likely be absolutely terrible at it. However, they all still have the baseline knowledge. They're able to assess patients, read charts, and report on vitals.
I just asked my wife (a psychiatry resident) if she could intubate/ventilate a patient. Here response was, "If I were the last person alive, I could intubate. You wouldn't want me to do it, but I could do it. I don't know how to run a vent, but I'm sure I could figure it out if I consulted with a doctor/therapist that does". I think most non-critical care doctors would express the same opinion.
What I'm getting at is we have a large amount of doctors that can act as multipliers for intensivists, hospitalist, ER docs, and pulmonologists. They are able to do much of the time consuming work while relying on specialists to guide overall care plan and intervene the on most challenging cases.

Given how medicine works, the chances of actually seeing this in action are low. But....it's an options.
The question in a lot of ways is how many exponential doublings do we have to have before this situation switches in peoples' minds from a peace-time inconvenience to essentially real war.
Right now, the death rate still isn't higher than a flu epidemic but just the number of known infections promises a lot worse and the potential doublings after that are terrifying.
It seems like there's an endless dialogue of:
A: How would you accomplish X?
B: I wouldn't, X is not what I do.
But we need to give the final answer:
A: I didn't ask whether you can do X. I'm telling you, "do X or many people die, you are all we have at this point. Think outside the box".
The question in a lot of ways is how many exponential doublings do we have to have before this situation switches in peoples' minds from a peace-time inconvenience to essentially real war.
Indeed. I was organizing some people to make face shields and was looking for a big room. When I talked to the city about using a school gym, one of the criteria was that everyone needed to have background checks. Because it would be in a school!
"The question in a lot of ways is how many exponential doublings do we have to have before this situation switches in peoples' minds from a peace-time inconvenience to essentially real war."
The millions of people who would die in a worst-case scenario are mainly demographics that society is already used to neglecting: the elderly, the terminally ill, those with lifelong chronic illnesses where any infection could be a killer, etc.
Therefore, I would expect this to continue to be considered more of a peacetime inconvenience than a real war. A frequent response to this is, "But they could overwhelm the healthcare system so you or me couldn't be treated for our needs!" Well, if the bulk of the population is left inconvenienced and unemployed for too long, I can imagine some ugly scenarios where the population demands, broadly speaking, that those demographics simply be triaged out of treatment so that they don't overwhelm the healthcare system for everyone else. This is said to be already happening in Italy to a degree.
Well, if the bulk of the population is left inconvenienced and unemployed for too long, I can imagine some ugly scenarios where the population demands, broadly speaking, that those demographics simply be triaged out of treatment so that they don't overwhelm the healthcare system for everyone else.
People imagining such triaging seem to think that a willingness to be appalling brutal means such brutality could be achieved with limited costs.
Italy's situation is far from the worst-case scenario. It's death rate is not that much higher than a seasonal flu, it's just the death-process that is far more messy.
Which is to say, let the infection rate get high enough and you'll have hospitals crowded with the young and healthy even if carry the old directly to the morgue.
Moreover, authorities shouting "all clear" in the midst of this dreck isn't going just summon a phalanx of consumers ready to go to restaurants, death chance or not.
In short, just because you're evil doesn't mean you aren't stupid too.
If you read my parent post in context, I hope it's clear that I mean currently in Italy, people are not dying at a rate higher than the seasonal flu BUT this has a big potential change if the infection rate were to shoot up (we know this is prevented by extreme quarantine measures, enforced by the army).
Your point still isn't clear or accurate. The worldwide CFR is over 4%. In Italy, it's currently at over 11%. The flu is nowhere near that level of risk. It's normally around 0.1% depending on demographic. Are you saying that the seasonal flu in Italy normally kills 11% of those who become infected? If that's the case, the facts don't bear that out.
That’s not true. Once you start getting into the tens of millions of deaths worldwide, that’s going to include a lot of young people and medical staff and people who will die of other treatable diseases or injuries because half of the doctors in the country are sick or otherwise occupied.
The problem is that X includes a nonzero risk to human life/limb that is the responsibility of the person doing X. If you are in charge of a hospital and just let Y people die because there's not enough qualified doctors to run ventilators then you can easily wash your hands of it as though it's not your fault. If you let less-qualified people run ventilators and Y/10 die from human error but you prevent 8Y/10 people from dying then all the families of the Y/10 that died from error are going to hold you responsible even though you minimized the number of overall deaths.
We have spent decades holding people systemically dis-incentivizing people from doing positive things in bad situations by assigning responsibility in this perverse "who was the last one to touch it" manner. Society has made its bed and now it gets to lay in it. Nobody is gonna be the one that bucks the trend and reduces and sort of real or perceived safety standard in order to increase volume of care until the situation becomes so obviously bad that not doing so is indefensible.
I don’t think there’s going to be a mindset change in the population. The absolute worst estimates are between 0.5 and 1 percent of the population dying.
> Thr absolute worst estimates are between 0.5 and 1 percent of the population dying.
There are news reports right now on HN on how the real death rate on countries that are not falsifying reports might be up to 4 times the assumed rate.
The hypothesis is supported by the increase in total deaths compared with the baseline, and after subtracting deaths linked to covid19.
This being true, we might be looking into 2 to 4% of the population.
You just asked a person qualified to give you their professional opinion and then you turned around and more or less completely undercut that professional opinion.
You need the experience and you need the detailed instruction. That's why there are certification programs around the operating of complex healthcare machinery. Just like you don't want a front-ender doing back-end or systems work you don't want your psychiatry residents to operate an ICU.
> Just like you don't want a front-ender doing back-end or systems
This is not the argument I'm making though. That implies the front dev has no oversight.
I'm making the argument that a frontend development can successfully complete features with the guidance/oversight of a backend dev. The results might not be ideal, but it can provide an acceptable outcome.

> You need the experience and you need the detailed instruction. That's why there are certification programs around the operating of complex healthcare machinery.
These programs are focused on developing individuals who can robustly and independently manage this complex machinery.
Should we also discredit airline pilots because laypeople have landed planes in emergencies? Or discredit sports professionals because many can kick a ball?
There are exactly 6 known instances of talk down landings that I'm aware of. All concerned general aviation and in one of them the person had prior flight experience. Several of those ended in a crash. A general aviation plane is in no way comparable to a large airliner, and no instance of such a landing has ever been recorded, nor has it been attempted.
Life is not a movie, some stuff is just hard and requires a long time of training before we'll let you go 'solo'. One mistake and someone ends up dead, there are no do-overs, there is no undo button.
The last thing ICU's need right now is on top of all the stress already going on there to be overrun by eager rookies that are trying to help.
The best we can do - and this is happening in some places - is to move up the training schedule and to graduate ICU nurses early. This is need for several reasons: to man the extra ICU capacity that is coming online and to take the place of those who have died or can't take it anymore due to psychological stress.
I think this sort of language is why a lot of non-professionals are sort-of balking. Life currently is like a movie. A zombie or some similar disaster movie, a situation where things are changing fast, where the normal plans are expected to fail.
...and requires a long time of training before we'll let you go 'solo'. One mistake and someone ends up dead, there are no do-overs, there is no undo button.
We are talking about a situation, coming up in X many days, when it won't be a matter of the authorities "letting" people try but a matter of the entire health system being overwhelmed. What are the other, workable plans you have for people dying in the parking lots of the emergency room? And yeah, this is a different world, one where we expect people to end up dead and we're asking how to decrease that are much as possible.
This horrible movie is the consensus of most projections. The question is not "could we deal with this? Can we play doctor, please!" but rather "how should we best deal with an ongoing disaster where we're assured, the doctors will be gone. Surely there's something one could beside 'die in place'?".
The last thing ICU's need right now is on top of all the stress already going on there to be overrun by eager rookies that are trying to help.
If the ICUs have a different, workable plan for when they are overrun with a massive number of patients, I'll be tremendously happy. The only thing I hear is "this won't work" "but what can we do?" "don't you understand that this won't work"....
> Life currently is like a movie. A zombie or some similar disaster movie, a situation where things are changing fast, where the normal plans are expected to fail.
No, because after a movie you get to go home, no matter how terrible it was. And in real life you don't get to go home. So you will have to trust in the people that have spent their lives preparing for stuff like this while we, the software smartasses were 'changing the world' with our SaaS toys.
Right now the best programmer is worth less than a mediocre ICU nurse, and that will remain so for a while. Afterwards we can all go back to pretending they don't matter but right now this is how it is.
> We are talking about a situation, coming up in X many days, when it won't be a matter of the authorities "letting" people try but a matter of the entire health system being overwhelmed.
That's a past station in some places.
> What are the other, workable plans you have for people dying in the parking lots of the emergency room?
I don't have any plans. They will die. Because we were too stupid to listen to those sounding the alarm when it mattered.
> And yeah, this is a different world, one where we expect people to end up dead and we're asking how to decrease that are much as possible.
We can decrease it as much as possible by stopping to move around so much. And yet, that seems to be too much to ask. Just now in another thread some religious guy claiming an exception just because the risk was low. I sincerely hope they'll all be fine, I also hope that if they are not that they'll trust their god rather than to hog precious ICU capacity needed by people who were careful and who did not seek this out on purpose.
> If the ICUs have a different, workable plan for when they are overrun with a massive number of patients, I'll be tremendously happy. The only thing I hear is "this won't work" "but what can we do?" "don't you understand that this won't work"....
The ICU staff is working double shifts and around the clock in plenty of places. They too get ill, plenty of them have already died. It's a bit late to stick your oar in now and make it your mission, I totally sympathize with the intentions but this isn't your fight other than to stay put, tell other people to stay put and accept that this story will not have a Hollywood ending for many people.
From what I have read the Italians have repurposed all kinds of doctors to be able to treat Covid patients as best they can with all available equipment. So I don't think it's too far out to say that in New York and other places you will see doctors stepping up and learning on the job in order to treat this disease. You will also see doctors coming into New York from other places to help.
Yes, and for doctors that may make more or less sense. But that's very far from the ideal situation: that we had managed to keep things under control when we could and that right now we stay home as much as possible to reduce the load on the system. But since people aren't even doing that (see this gem of a thread: https://news.ycombinator.com/item?id=22724268 ) I fail to see why we should at the same time break things even further.
Let's first all stay the fuck home, then ensure good personal hygiene and if and when infected self isolate as much as possible and leave the rest to the HCWs who are risking their lives in the most literal way possible.
All this well intentioned backseat driving isn't going to move the needle, not even a little bit.
This is a good point. Preventative medicine is the best medicine. That's true in general, but is especially true during this type of crisis.
We should also be more strict about isolation measures and lockdown, both individually and as a matter of policy and enforcement. That would keep our hospitals from flooding, to a much greater degree than an army of respiration therapists and ventilators would.
> All this well intentioned backseat driving isn't going to move the needle, not even a little bit.
But how else shall we spend our weekends locked indoors without pointless arguments on the internet? ;)

This language of addressing each posters as if they personally had this intention is pretty bizarre. It's very much the language of "proper authorities are taking care of that." I don't personally have any intention of jumping but I'm part of a community and part of a situation where the proper authorities aren't taking care things.
> The only thing I hear is "this won't work" "but what can we do?" "don't you understand that this won't work"....
I find it doubly frustrating because the majority of these are asserted as fact, typically based on flawed reasoning, when what they really are, are estimations/predictions.
If this lack of concern (if not outright disdain) for correctness becomes too prevalent within a society, I worry that it may affect the quality of our decision making.
The flawed decision making was right at the start, when this thing could have been bottled up, and then after that at just about every junction where decisions were postponed. Now it's too late and everybody and their brother will start telling the ICU personnel how to clean up our messes?
It could be, I'm not overly familiar with those details, and therefore hold no opinion. Only when I sense I have a fairly decent understanding of a situation do I form any opinions on it (or more accurately, this is how I try to approach things!). And often even not then, as I have awareness of and profound respect for the ~multidimensional complexity of reality, where many of the variables and associations involved are completely invisible from an individual human perspective.
Regardless, is this somehow related to my comment above?
I now don't remember where I saw this, nor can I find it... but I swear I had seen something in the past week or two comparing how much retraining different medical professions needed to quickly get useful for staffing ventilator technology, and veterinarians came out on top; so like, people are (unless I dreamth this?!) looking into reusing people.
The US did a disaster prep simulation for virulent flu, that involved a shortage of ventilator scenarios. They took people with something approximating medical backgrounds, including nurses, other kinds of docs and vetinarians, and gave them training in how to use a ventilator. After two days they were given a test and the vets had the best score.
Doctors that don't know how to properly operate a vent are currently a problem in the US. Not blaming them, as there doesn't seem to be any real alternative.
I don't think you can pick a single /r/medicine thread as evidence of a widespread problem. My wife and every other doctor to ever practice medicine can give you anecdotal examples of other doctors mismanaging patients.
Another thing to consider is this is a rapidly changing/progressing disease and there are no standards. The opinion of a recently graduated fellow has different biases than an experienced attending. They can both be correct while disagreeing on the specifics.
Nah, we don't have all those doctors for the sick. We have doctors for every type of plastic surgery you can imagine, doctors for aging, doctors for athletic training, doctors that specialize in hips, others in just ankles, also shoulders only, others that only do laser eye surgery, others that only do teeth, some just for gums, some only do tooth implants. And on and on.
There is a shortage of doctors that actually treat sick people.
Do you have any idea how long it took your wife to learn to achieve the level of skill she is at? Let's say this was WW3, and we somehow lost 75% of these specialized personnel, what would be a ballpark estimate to get a reasonably intelligent person with no medical experience up to a "functional" level?
> what would be a ballpark estimate to get a reasonably intelligent person with no medical experience up to a "functional" level?
It really depends and I'm speaking out of my comfort zone here.
Becoming a doctor takes a really long time because it includes a LOT of background and general medicine knowledge. Doctors know a lot about medicine outside their speciality.
Med school is 4 years (2 years of bookwork focus and 2 years of clinical focus) and builds on undergrad significantly. Residency is 3+ years. I'd say the majority of people with STEM backgrounds could have function acceptably as a general doctor with 2 to 5 years of postgrad training. Surgeons are built much more on experience so that's very hard to fast track.
In my opinion, the real measure is the ability to handle edge cases/unusual cases. Specialized/limited scope workers, especially those with the direct support of an experienced individual, could pick up tasks much, much more easily as long as an expert is there to take over the challenging cases.
Sorry, I probably should have been more clear, I was referring to teaching someone only the skills necessary to operate a ventilator, in a supporting role to a properly trained medical professional, who would handle the more complex situations.
I'm willing to consider that it isn't possible, but if that is the case, I'd be keen to know the particulars of why. If there happened to be a documentary on respirators that covered some of the complexity involved, I would be on my couch watching it.
If you repeat the same task 20 times a day you rapidly become an expert at it. If all the patients have exactly the same condition I would assume that the staff would quickly upskill to treat that condition.
Typical for tech oriented people to look at it this way. Patients with the same condition are still meatware and each has the capacity to develop their own variation on a large number of themes all of which require adaptations in treatment regime and sometimes very rapid intervention lest you lose a patient.
I assume OP is referring to conditions during a pandemic. There have been numerous reports out of Italy about how they are operating under a wartime triage system - presumably under these conditions the response is more focused on repetition of the same process rather than unique personalised care.
No, it's the fact that you need unique personalized care that makes it complex.
Triage is just to deal with limited resources, essentially it divides the applicants into 'walking', 'dead' and 'care', and the fewer resources you have the more people will get sorted into the 'dead' category even if they still have a pulse when you see them. The 'care' category will still get unique personalized care otherwise you might as well sort them into the 'dead' category on the spot.
It's not a choice between a doctor and a layman, though. It's a choice between a volunteer who's only trained in the very basics and watched a couple of intubations, and nobody at all.
How much training does someone need before they become a clear net positive for the patient?
A couple of years should do it. A volunteer would not just be a 'net negative' but would leave a lot of dead people. Why is it so hard to see that the people that operate this stuff are not just button pushers but specialists that have been schooled over years to take care of people?
The ICU staff would not even allow the doctors to mess with their setup because it is critical and it is their responsibility until some either dies or is discharged from the ICU and allowed to move back to a normal ward.
Again, it's clear that a volunteer is far worse than a trained professional. At what amount of training does a volunteer become better than nothing?
If I had to choose between an uncontrolled emergency landing, and an emergency landing done by a volunteer who did two days of training, I'd choose the volunteer every time. I understand that the volunteer does not have the training to fly or land safely and that becoming an airline pilot takes a lot of training, but that doesn't matter if there's no pilot available.
If 20% of patients die with trained ICU staff, 90% die with no ICU staff, and 70% die with a trained volunteer, and you have no more ICU staff, then the volunteer is a net positive and the volunteer has left a lot of dead people. The question is not whether the volunteer is even anywhere close to a trained professional in effectiveness, it's whether the volunteer is better than sticking a red or black tag on someone's bed and leaving them to die.
Yes, people in this thread are letting the perfect be the enemy of the good. Everyone knows that doctors are overqualified for the vast majority of tasks they are responsible for. Normally, there's good reason for this, because you want a highly-trained eye to spot unusual and atypical cases.
But when you're dealing with a pandemic, you can do without. Do you really think that your typical doctor spent all that much time in med school or residency learning how to operate a particular kind of machinery? If we have the ventilators, we'll be able to find people to operate them.
> Yes, people in this thread are letting the perfect be the enemy of the good
No, it's because medicine has a very low fault tolerance, and requires a large body of technical knowledge to even understand what needs to happen for your patient.
Having a team of incompetent clinicians perform complicated medical procedures "good" as a layperson still results in disproportionate people dying, that would have survived under a competent practitioner.
> [...] would have survived under a competent practitioner.
Bringing us back to the topic of this thread, a potential lack of competent practitioners if the pandemic worsens, and what the best solution to address this would be, such as a COVID-specific ventilator training.
Because the difference between letting someone die under inappropriately-applied ventilation versus just letting someone die is the occupation of a perfectly good ventilator. One that could be used to actually save someone. If you're in the business of killing patients, a gun would be more economical than a ventilator.
Heh, if it comes down to it we will see a lot of creative new processes that are apparently beyond the imaginations of many here.
The army knows how to train people to basic competency very fast, and they know a thing or two about drafting volunteers ;)
Not everyone need be coming in completely untrained. And job shadowing is the obvious thing most people are over looking. Nobody is going to dump a bucket of scrubs with 30-days classroom training all over the ER floor. Groups of trainees would be shadowing trained professionals 15 hours a day.
Really? They spend 8 years learning how to operate a ventilator?
Medical professionals learn how to do their entire job in a similar time frame. Ventilator operation is surely a small part of that. I'd be astonished if it would take someone more than a week or two to learn the basic mechanics of how to use a ventilator. None of the theory or nuances, but a course that says "hook it up like this, do X, Y and Z and come get me if this or that happens".
Ask any doc if they want 4th year medical students to help in the ICU with COVID-19 patients and they will say “No, they would most likely be a hindrance rather than help”. If a 4th year medical student can’t help, then why do you suppose somebody with zero training would?
I'm not saying "zero training". I'm suggesting the minimum training necessary to run a ventilator. That way doctors or nurses could simply hand off care to ventilator-operators who could contact the doctor or nurses if things got out of control. This wouldn't be as high quality care as people would usually get, but hopefully it would be better than nothing.
Regarding whether doctors would want undertrained help - that's immaterial. If current healthcare workers have the capacity to handle the pending wave of sick people, then that's great and we shouldn't get in their way. If they have another, better solution, then let's do that. If the alternative to having minimally trained people operate ventilators is letting people die without any intervention - I'd want to see some explanation or evidence as to why letting people die is better.
I'm not an MD but I've had contact, on-and-off, with mission-critical equipment in the energy sector (according to my university I'm an EE but I was cleverly disguised) and then I've worked in the medical equipment industry for a few years. I would be very, very surprised if the parent comment(s) weren't correct. Training, no matter how intensive, is no substitute for education.
Getting nurses, doctors from other specialties, or even medical students through an intensive training is one thing, and I suspect it's actually a good idea. These are people who have (or, in the case of students, are at least likely to have) the knowledge required not just to learn how to operate a piece of machinery, but also to understand when they're in over their heads, when to ask for help, and to understand the magnitude of what they're doing.
But IMHO -- also based on my experience in other potentially dangerous fields -- putting people with zero medical education except for a thirty-day training in charge of observing people in a life-or-death situation is a really bad idea. Under-educated, even if well-trained assistance has a very high potential of making things worse, not better -- worse than doing nothing at all, that is.
Running a ventilator as in pushing the right buttons is something you can learn to do just by reading the manual. I can obviously operate every medical device I've worked on. I've obviously had more than 30 days of exposure to them. And nonetheless, I think the chances of getting someone killed by operating them are extremely high. I am also 100% convinced that they are much higher than the chances of someone who's had some medical education doing the same thing, even if they've never seen that machine and have never read the manual. What doctors and nurses do with the things I've built is way above my level of understanding.
I can't speak for medical students but I can guarantee that, if you let 30 final-year engineering students walk around a power plant without constant supervision, one of them will get themselves killed by the end of the day. And that's after three years of education. 30 days shouldn't even get you past the lobby.
I fully expect that a person who has only thirty days training will be worse than a professional and their relative incompetence will kill people. I don't understand how that is an argument against the plan to train volunteers though.
I'm reading that hospitals may be overwhelmed. I understand that to mean there will be more people requiring intensive care than capacity to give intensive care. If the choice is between the hospital sending people who need ventilators off to die and sending them to someone with thirty days of training and good intentions... Well, my intuition is that you'd have better outcomes with the latter.
The point is not "can we do this without killing people." Nope. More people will die with amateur ventilator-operators than professionals. What I'm suggesting is that more people will die without amateur ventilator-operators in the event hospitals are overwhelmed.
If we think hospitals are going to be overwhelmed in thirty days then the time to start training amateur ventilator-operators is now.
I got your point, but I am not at all convinced that sending in people who have nothing but good intentions and 30 days of training, at a scale, and over a long period of time, will result in less harm (including among those with good intentions) than not bringing in extra personnel. Especially in ICU, which as far as I can tell is the RF engineering of medicine.
It takes an inordinate amount of time just to teach people what they can and can't touch and when and how, how to wash their hands properly, how to put on and take off their masks/gloves, and where to stand so as not to be in the way of people. All this in the context of a pretty contagious disease. I am pretty sure that, within 20 days, most of the volunteers would be infected themselves, and end up putting even more strain on the system.
I've been in an OR as part of my job, and I'd definitely think twice before enrolling in a program like this one (and definitely not just for my own safety, although yeah, that would be a big factor, too).
I've sure you've already considered this, but wouldn't any kind of training program of the sort you describe risk diverting resources from current operations?
It's possible. That's something that would have to be weighed against how bad we expect shortages to be and how much we expect amateur ventilator-operators to help.
Given that we likely have more spare doctor cycles now than we will in the future, we should utilize them now. We can also do things like hire doctors from countries not as badly stressed to come teach the classes.
There are clearly a lot of contrarians in this thread, perhaps that is because the premise of a flooded healthcare system is still too impossible for some to envision.
And of course there are many levels to addressing bottlenecks. For example, operators wouldn’t have to be amateurs at first, they could be any of the non-essential medical professionals who are not able operate business as usual due to the virus. Could a podiatrist or urologist operate a ventilator given enough training?
In general we are brainstorming proactive measures. I think, at least in the US, we continue to have a reactive as opposed to a proactive strategy because of our decentralized government structure as well as the delicate balance between effective mitigation and maintaining social order. While we should be leveraging the current shelter in place strategy to build as much healthcare infrastructure as possible (both physical and technical, as per the thread) to handle slowly returning society to normal operations, we probably are not moving fast enough. In several weeks, as the unemployment and anxiety builds, so too will unrest. And I guess then it will really be a test of a nation’s people.
I believe the point is that the minimum amount of training required to be of greater help than hindrance (i.e., net benefit) in an ICU and running ventilators is sufficiently high that it's not a small thing to spin up a cohort.
To my exceptionally limited understanding - and I would love to be corrected if I'm wrong - operating a ventilator correctly is not a matter of standing in front of a machine and watching a few numbers for problematic readings. That can be done by machines and computers. What requires training is everything else around it, which requires an understanding of medical protocols, anatomy, the ability to respond usefully to emergencies without being in the way, and so on.
Which is to say that this is not something that highly specialized and narrow technicians can be usefully trained for in a very short time at this particular moment.
That's not to say your idea is bad! It's definitely good and worth exploring in the future. There will be time to explore how to have smarter tools that can be used with a less general skillset can be developed. There will also be time to explore how to develop specialized and narrow curricula for such things - itself not a trivial task.

This thread isn’t about automating medical professionals responsibilities one task at a time, or attempting to step on their egos. I’m as proud of their title, their coat, and their debt as they are.
If a pandemic respiratory virus is not the time to “consider exploring” this idea, when is? When people are left to die in their homes because the ambulances stop taking calls...?
We are, of course, just shooting out ideas of grandeur. A reactive strategy will be maintained, people will die, and everyone will throw their hands up in the sky and say “nothing else could have been done. March simply was not the time to think about COVID-specific medical operation efficiencies. There will, however, be a time to explore...”
I'm trying to suggest, as gently as possible, that a time when our medical system is verging on being flooded may not be the best of all possible moments imaginable to add a significant resource-consumer in the form of an experimental mass training program. I am attempting to encourage more systemic thinking and greater consideration of context. I understand that some may disagree with some or all of these arguments.
Please accept my deepest apologies if I have in any way seemed to imply that the current reactive strategy is an ideal long-term solution. I do not in any way think this.
Don't hesitate to ask if there's anything else I can clarify for you - I frequently fail to express myself as well as I'd like.
> It's definitely good and worth exploring in the future. There will be time to explore how to have smarter tools that can be used with a less general skillset can be developed. There will also be time to explore how to develop specialized and narrow curricula for such things - itself not a trivial task.
This will happen soon or not at all. The AMA and its equivalents worldwide have a very consistent attitude to anyone, anywhere being allowed to do anything a doctor can do. It should not be allowed. Psychologists should not be allowed prescribe; nurse practitioners should not be allowed practice independently under any circumstances, etc.
Pretty reasonable if you ask me. History is littered with quacks and snake oil salesmen. There is a reason why becoming a physician is such an arduous and selective process.
> History is littered with quacks and snake oil salesmen.
Indeed, doctors did more harm than good until the early 1900s at the earliest, and we can only be sure that they were on net leading to lower rather than higher mortality with the introduction of antibiotics.
Because it's common sense that an invasive medical procedure needs to be administered by someone with some semblance of competence in medicine, if you expect the patient to have a shot at not dying. An emergency doesn't change the hard technical requirement of administering ventilation.
Or rather, this should be common sense, but the over-inflated egos on HN don't understand that it takes more than knowing which button does what to operate a ventilator. Being able to hold a paint brush is a very different skill level than painting a portrait.
I can infer some useful information about you from this thread. It is that you actually don't give a damn but you love arguing, the more the merrier and no matter whether or not you stray far off-topic, you'll be happy because that gives you yet another thing you can argue about.
If there is relevance to this conversation in the 10,000 or so words that you have spent on this thread then I fail to see it, so I really don't know what this particular comment is trying to achieve other than that it has me considering whether I shouldn't just plain give up on HN.
Don Hopkins has it right, sealioning is the perfect term to describe what you are doing and it is a destructive thing on something as fragile as this forum because it narrowly fits the guidelines and yet makes it impossible to have a normal conversation. It's the online version of passive aggressive belligerence with a veneer of sincerity on top.
That inference is 100% consistent with his past behavior as I've experienced it.
His arguments are incoherent, rambling, and and focused on nothing but derailing the conversation and wasting everyone's time. He perfectly fits the definition of "sealioning". He even admits he knows what it is and is familiar with the web comic that coined the term, then in the same post, he continues to behave as if he's working directly off the wikipedia definition, acting out its every point and symptom, as if it were his playbook.
When confronted with arguments that directly address his points, he complains and runs away and refuses to respond to them. His "concern" for the topic and interest in having a conversation is totally insincere. His only goal is to waste time. Only when he can waste time and divert the conversation away from the point, does he bother to reply. But once there is no way out but to confront the glaring contradictions in what he wrote, his suddenly disappears and has no more to say.
It's supremely ironic and proves he's a troll with absolutely no sense of self-awareness, when he says things like "I'm not seeing much relevance to this conversation", after spending so much time and energy trying to derail the conversation with irrelevant bullshit. That should serve as a warning and warning sign to anyone tempted to engage him in conversation, or take anything he says seriously.
Sealioning is a Gamergate tactic, so it's quite possible he's one of those disruptive children, and that's where he learned it from. He's certainly doing it regularly and systematically and by the book, as if it's a job he's been trained to do, he has a checklist of talking points and techniques, and is being paid for his time, number of posts, and number of words.
Another tactic you can see him practicing, which we're all familiar with coming out of the White House, is psychological projection. Trolls like misterman are fully aware they're sealioning, know all the terminology because they study and emulate it, and they love to throw around and misuse terms like that themselves, to attack other sincere people for doing what they're actually maliciously doing themselves, to make it seem like it's just "both sides", which it's not.
It's not just an internet thing. Here's an example of how racists sealion and project in real life:
Thank you! His pattern of sealioning is outrageously obvious and blatantly unoriginal and formulaic. It's as if he has a dog-eared copy of "Sealioning for Dummies" marked up with yellow highter pen and bookmarked with post-it pads, that he's following step by step, page by page, checking off each technique and trick as he tries it.
Sealioning is related to the Gish Gallop, to which there are some countermeasures that work (beyond systematically flagging his post every time he does it, which is the least we all can do to protect the community).
The approach that worked for me, and shut him up cold in his steps and made him suddenly retreat, is to be very calm and structured about your replies, and not let him derail you, which is something that we can all cooperate together on, and support each other by doing together as a tag team.
Carefully chose and enumerate your questions, and repeat them when he doesn't answer them, but don't get distracted by his off-topic diversions, or his passive aggressive belligerence with a veneer of sincerity on top. His pseudo-intellectualism and pretend-open-mindedness and saccharine-sincerity is all just an act, and you don't owe him the level of courtesy that he is pretending to extend to you and mocking you with. I can practically see him laughing to himself (and his Gamergate veteran buddies) behind the keyboard every time he thinks he's fooled anyone into taking him seriously, because he certainly doesn't believe what he says.
Just calmly point out every time he ignores one of your questions or somebody else's questions, or tries to derail the conversation. Keep relentlessly pushing him back onto the topic, and never let him derail you. When I did that, he was mortified and childishly complained that I was not the boss of him, and that I could not tell him what to do, or force him to answer my questions, then he immediately lost interest and fled without another word, because the last thing he actually wanted to to was to stay on topic and answer the questions I would not stop asking.
During a Gish gallop, a debater confronts an opponent with a rapid series of many specious arguments, half-truths, and misrepresentations in a short space of time, which makes it impossible for the opponent to refute all of them within the format of a formal debate.[3][4] In practice, each point raised by the "Gish galloper" takes considerably more time to refute or fact-check than it did to state in the first place.[5] The technique wastes an opponent's time and may cast doubt on the opponent's debating ability for an audience unfamiliar with the technique, especially if no independent fact-checking is involved[6] or if the audience has limited knowledge of the topics.
Generally, it is more difficult to use the Gish gallop in a structured debate than in a free-form one.[7] If a debater is familiar with an opponent who is known to use the Gish gallop, the technique may be countered by pre-empting and refuting the opponent's commonly used arguments first, before the opponent has an opportunity to launch into a Gish gallop.[8]
I agree. And he'll be very easy to recognize when he tries to create another sockpuppet account to troll with after he's banned, so we'll just flag that one too when we recognize him trying again.
> Because it's common sense that an invasive medical procedure needs to be administered by someone with some semblance of competence in medicine, if you expect the patient to have a shot at not dying.
Common sense does not determine how difficult something is, how difficult it is determines that. Reality, for the most part, flows into the brain from the outside world, not the other way around.
> An emergency doesn't change the hard technical requirement of administering ventilation.
Neither does common sense. The "the hard technical requirement of administering ventilation" is precisely as hard as it is. So, how hard is that? You represent (in poker parlance) that you know the answers to such things, but you seem reluctant to provide evidence.
> Or rather, this should be common sense, but the over-inflated egos on HN don't understand that it takes more than knowing which button does what to operate a ventilator.
This seems a bit ironic, because no one other than you has made that specific claim.
> Being able to hold a paint brush is a very different skill level than painting a portrait.
Now this statement is actually correct, but unfortunately I don't think it has much relevance to the topic at hand.
For starters, sincere apologies. You asked me nicely to stop this behavior in the past, I didn't, and you subsequently rate-limited me. After some time, once I had gone through some "personal work" as they say, I asked for this to be removed, you kindly accommodated me while repeating your earlier warning, and I promised to comply.
I think it is more than fair to say that I have clearly violated your trust - although, I would also say, only in a sense. I will describe the details of my thinking on that (the method to my madness so to speak), in a reply to your last email when I can find the time (next few days or so). Not that you care I imagine, just an fyi.
Just as a preview of that email, I won't be arguing for a removal of my rate-limiting. You have your hands full on HN maintaining some reasonable level of decorum (herding cats) in discussions, in a world that seems to have almost gone mad. This is no small task, and I fully appreciate why you must resort to this. No disagreement from me on this particular decision.
Rather, in the email I will attempt to explain the reasoning behind my (deliberately) anomalous conversation style (this entire comment, for example). Whether you will agree with my thinking, or even have the time to give it any serious thought, is of course up to you. As I said, you are a busy guy with a thankless job, and if you decide that you can afford little time to spare on entertaining the out-of-the-box theories of some random crackpot (who also exhibits numerous signs of classic schizophrenia) on the internet - no disagreement from me on the decision. You have been more than fair and patient with me under the circumstances as you understand them (and yes, I am aware of the ~"implied condescension" in that statement - I believe noting such things can be useful to minimize misunderstandings regarding beliefs &/or intent).
I've anticipated the day your hammer would come down on me, as did some of the folks I was in conversation with - it seemed quite inevitable. The only ways that quickly come to my mind for how this eventuality could have been avoided are:
- I personally decide to "knock it off" (rather unlikely, to say the least)
- Multiple people happening to notice a pattern in behavior, and realizing "what it is I'm up to", or "what I am trying to draw people's attention towards". To my mind, "what I am up to" is so blatantly obvious that it boggles my mind that not one single person, in a community of thousands of the planet's best and most logical minds, has noticed the method. One person I can think of noted it somewhat, but I got no sense that they noticed the systematic and intentional pattern, but rather were merely thanking me for "pointing out" when we were straying from evidence-based discussion in his particular sub-thread. One thing I speculate people may be overlooking in this situation, or "the point I am trying to make", is that there is a "pattern in behavior" that can be observed not only on my behalf (this one is easy to see), but also in the behavior of my counterparts, in essentially every conversation I've participated in recently.
Wrapping up, I'll just say: no hard feelings on my end. On the contrary, I am sincerely grateful for your patience with me. You've got a job to do here, you did it with amazing restraint under the conditions, but at the end of the day, sometimes pragmatic justice must be dispensed to maintain overall order.
I have been nursing for years and the battle of skills has never stopped. Only doctors can do A B or C. Then at some point the registered nurses start doing it and then eventually the licensed practical nurses get to do it. The shift in skill set is always happening and often fought from the top ie doctors fighting to keep the skill to theirselves. You are absolutely right there are plenty of people who could efficiently watch the ventilator patients and report back the important facts. And you are also right they don’t need to do a perfect job only better then just letting people die with no chance. That is what triage is all about. All hands on deck. It is just really hard to start giving extra direction and have new people on the ward when the shit is hitting the fan and that alone can fluster staff. But in a pinch we won’t have enough staff so other rolls need to be taken or people will die.
Thanks for adding your expertise to the discussion.
It's quite interesting to hear the opinion of someone who has both education and hands on experience directly in the field, and then compare that opinion to the opinions of those who have neither.
You’re comment reminds me of the reluctant success of sending teenagers on bomber raids in in WWII over Germany. As opposed to relying on only experienced airmen, which there went enough of.
Younger doctors without 4 years onsite experience are still probably extremely capable and I’m sure you’re right, they can learn how to do a subset of their eventual job very short amount of time and do it well if given the chance.
It sounds like there is some fundamental idealogical opposition to this.
I have a friend who is going through her residency now, she has to deal with a lot of very unhealthy psychological and physical treatment (ridiculously long hours) to get through it. Sounds more like a hazing than a professional introduction.
It's not the age of the pilot or doctor, but the experience. In WW2, some pilots were considered combat capable after 150 hours of flight time, basically 6 months. They died. Eventually the flight programs ended up taking 1.5-2 years on average to crank out a new pilot. A pilot that also died quickly.
Now in war, you have to throw bodies at a problem, and if the bodies end up 6 ft under, that's war. But generally bad pilots only kill themselves, they don't kill patient after patient through malpractice.
It seems like you've outlined a situation that could well be true. The US indeed has a training process that only generates useful competence with a full 8-12 year apprenticeship of hazing and theory.
Of course, it flies in the face of a common sense view that someone careful, able to follow orders, just hold things or press button etc would provide some use in a world where the doctors are fundamentally limited.
It seems like a world where the medical industry has piled goldstandard-or-nothing upon goldstandard-or-nothing approaches, to the point yeah, doctors really don't know how to produce useful people without those fricken' eight years or twelve years. Well friend, you should start thinking "outside the box" about how to make other people useful or many, many people will dies.
FYI: The US produces field medic with 16 week training period after basic training. That might who you want attending to you but things are going to be resembling a war zone really soon.
In a huge medical emergency, when people essentially desperately pleading for a ramp-up of the effectiveness of medical personnel, it's kind of mind-boggling that the only answer you're giving is sneering at how little the layman knows (and yeah, that seems like a standard answer doctor in the US are going give).
And, yeah, maybe I know little of what exactly ICU processes are but it seems indeed implausible that there are no intermediate levels of skills that are the slightest bit helpful, just about physical task can aided by a "third hand" etc.
> Of course, it flies in the face of a common sense view that someone careful, able to follow orders, just hold things or press button etc would provide some use in a world where the doctors are fundamentally limited.
Doctors don't want someone with zero training "helping". That's for sure. The original idea of 30 days training is an end of the world worst case scenario. No one wants that right now. And someone with 30 days training is more of a hinderance than a help. Press more techs, nurses and PAs into service first.
But my SO runs, (COO), a system of hospitals. Including some teaching hospitals. And part of their plan definitely includes sequestering final year med students and all residents at their respective homes. Apparently the idea is that as hospital staff go down, this pool of residents and med students can be drawn on.
I know she stays up nights worried sick that residents might go to a party, or invite their boyfriend over, or engage in some other risky behavior instead of stay home alone and safeguard their health. So I get the idea that they really don't have a backup to that plan. I suspect med students and residents are a pretty critical part of the plan for surge operations across the nation.
Just pointing that out because I think hospital administrators and medical directors are starting to plan on doing things they wouldn't normally do. Like pressing 4th year med students into service, or taking 68 year old women off of ventilators if a 33 year old woman presents with a need for it. It's not so much a question of what doctors want to do, as it is a question of doing what has to be done to get through this with the maximum number of recoveries.
Reminds me of some of the horror stories from the peak of the outbreak in Wuhan. Doctors and nurses treating patients without any PPE because, well, there wasn’t any left, and they had all tested positive anyway.
I don’t know what the fatality rates were for those healthcare workers at those facilities, but it would be good to know for future reference.
Patients are continuing to emit more viruses as they breathe and cough. Put enough viral load into the health care worker and they'll be in just as bad shape as the patient regardless of how naturally resistant they are.
There's talk along those lines. Not sure what they've settled on? Keep in mind, they don't really know how crowded these facilities are gonna get. Space may be at a premium. But yeah, at the same time going home is not always the best idea.
> The original idea of 30 days training is an end of the world worst case scenario.
The person was asking a question, not proposing a plan of only training people for thirty days.
This thread is a like a giant version of that telephone game that we used to play in school, except in that game you didn't have the advantage of reading the exact words that the person said, as we can in this thread.
Thanks for your comments in this thread. Some people seem to have an axe to grind concerning the hubris of software hackers and are pushing that debate rather than addressing the question.
Several schools, after requests, are graduating students early, precisely because of covid. And I don't think normal times and these are the same. Having younger, less likely to be infected staff is not nothing. And the variety of tasks is a lot lower right now, than during more typical times.
I would be surprised if any of these students will be in the ICU. Most likely they will be assisting with more mild patients and freeing up experienced doctors to help with more severe patients.
I think it speaks more to the fact that medical school is mostly focused on book learning and residency is when doctors get most of their hands-on experience.
Intubation is a delicate procedure, error prone and risky for the person performing the procedure because a lot of stuff gets blown back at you if it doesn't work well the first time around. It's one of the major reasons so many healthcare professionals end up infected, and given that these are the worst patients and their viral loads are very high that risk is even higher than it might seem.
Doctors and nurses probably aren't trained how to run an ICU, they spend more than a decade learning about human bodies and they only have so much time. If corebit happens to be an Operations Research specialist then it is reasonably likely that they would be better at running an ICU than a typical professional medical worker.
Medicine has traditionally had a problem with a large number of very clever people who are sufficiently insulated from other communities that they are a bit behind the times. A good humourous example is the 1994 paper where a doctor will rediscover calculus.
> If corebit happens to be an Operations Research specialist then it is reasonably likely that they would be better at running an ICU than a typical professional medical worker.
Why do people on HN consistently presume that they somehow know better than the experts? It’s distressing to me that anybody can say something like this with a straight face.
Obviously because being an ICU doctor isn't something hard like writing code. Fewer buttons on a ventilator! /s
But seriously, the amount of people on here trivializing modern medicine isn't helping matters.
Granted, neither is business-as-usual, but a 30-day "ventilator boot camp" for untrained professionals is going to kill far more people than it helps. And a poor allocation of resources during a time of scarcity.
Nobody wants to respond to your attempts at sealioning. Quoting text to you isn't going to change your mind or behavior.
Everything you've written here is inconsistent and contradictory, and you desperately try to derail the conversation and change the subject whenever anyone points that out, then you run away when you realize you've painted yourself into a corner and are getting called on it.
Just look at how many downvotes and flags you're getting, and how many of your postings are light colored, dead, and hidden. You're well on your way to a shadow ban. I wonder how long it will take you to figure it out that the only people replying to you have "showdead" set to true, because they love to see you floundering.
If somebody's paying you by the hour for trolling, then they certainly are not getting their money's worth, because the moderation system is working, as the text in your posts becomes lighter and lighter until your posts are hidden and nobody sees them, thankfully.
Go back to Gamergate where you came from, mistermann.
Again, nobody is saying that ventilator boot camp graduates should replace doctors. If there is a concern that there will be more people who need ventilators than we have medical professionals to operate ventilators - then the answer is that we need to quickly increase numbers of ventilator-operators - even if they are substandard.
Perhaps you think our capacity won't be overwhelmed. Then it would make perfect sense not to bother training amateur operators. If you think an amateur operator is worse than no operator, I'd like to see your evidence. If all you have is your intuition then my intuition is that you're wrong.
No, it's that I'm aware that "ventilator bootcamps" would be a resounding failure that would kill more people than it saves.
Going from zero to medical professional - not a doctor, just someone who can perform invasive medical procedures without killing a large number of people - isn't 30 days of work. Ignoring that reality will recklessly endanger people's lives.
If we're talking veterinarians, dentists, nurses, residents, MDs in unrelated specialties - then sure! They actually have the requisite knowlege and manual dexterity to cross-train. But going from, say SWE to ventilator operator, is not a 30 day crash course.
> If you think an amateur operator is worse than no operator, I'd like to see your evidence. If all you have is your intuition then my intuition is that you're wrong.
Because then you end up wasting a life and keeping a ventilator occupied, when there are much more efficient ways to kill patients that don't involve misusing a ventilator.
Former scientist, including (lab side) FDA trials. Medicine is complicated. Even sterile technique, to make sure you don't inadvertently give your patient a life-threatening infection in the process of "helping" them, can take years to get right. This is true of the most routine aspects of any kind of medical work.
But, do tell: since my "intuition" is so obviously wrong, I want to hear all about your empirical research. Or let's just start with your credentials, medical or otherwise.
Earlier in this thread it's stipulated that the bottleneck is not the number of ventilators but the trained people to operate them. As such, training more operators is an obvious solution, and allowing the new operators to be substandard will mean we can get more operators faster.
This pretty much dissolves your only real objection, that we'd be keeping a ventilator occupied that would otherwise be in use. Nope. The solution to a deficit of ventilators is producing more - not letting people die without them.
Generally, you are trying to invent reasons and restrictions to make trying to train ventilator-operators seem like a bad idea rather than understanding or advancing how the idea might be viable. An example of this is how you acknowledge that training other medical adjacent professionals (e.g. vetrenarians) would likely work. Great, you agree the idea could work. If you expect that our capacity will be overwhelmed then presumably you think we should training additional operators. Instead of reaching that conclusion you imagine reasons to object to the idea though.
A SWE would likely be worse than a vet after a bootcamp. That's a good reason to have some entry requirements to the bootcamp and those requirements could be relaxed or strengthened depending on where we expect demand to be in 30 days relative to supply. A SWE through a 30-day bootcamp would likely be better than nothing.
The other main constraint you've imagined is that they would need to save more people than they kill to be worthwhile. No, they'd need to save more people than would die without them. If it would be better to just struggle to breathe than have an amateur operator, that would be an argument against them.
Your credentials, whatever they are, haven't equipped you to clearly communicate your reasons for opposing this idea. As I mentioned, it seems like you actually support some version of it.
As the contrarian, can you at least enlighten us to what, in your opinion, would be the best strategy to proactively address potential bottlenecks? I think we can all agree, career shaming aside, that medical professionals and engineers of all varieties actively participate in mindsets geared towards problem solving.
So in a hypothetical situation, where existing permanent healthcare infrastructure is at capacity, field hospitals are setup and existing medical professional staff need to be divided amongst the existing and newly supplemented infrastructure, what is your suggestion to save the most lives?
This exercise of sharing ideas, informing, critiquing is what this forum is for. Disagree and casting shame for a lack of first-hand professional experience is not educational and it’s not what this forum embodies.
I want to be as informed as possible so I can call BS when politicians say “nothing at all could have been done.”
I fail to see how explaining that, "Yes, you need to know medicine to practice medicine, or people will die" is considered being contrarian. Would you rather just revel in ignorance?
So here's my idea: stop treating invasive medical procedures as something that can be trivially learned in a short amount of time. In short, drop the God complex. You're out of your depth here.
The need for action doesn't mean acting foolish. Irrational behavior in the name of "just doing something" will needlessly deplete more resources.
For one, if I were hypothetically responsible for addressing this crisis, I would be talking to the nurses and doctors to figure out what level of training is actually necessary to operate these ventilators. I'd also ask what else they actually need: if we get them ventilators but nothing else they're short on, we're still in trouble. In other words, I would recognize that I'm out of my league here and ask the actual professionals on the front lines of this crisis.
As I mentioned above, cross-training medical professionals in adjacent fields sounds more practical. Allowing nurses to do more of what the doctors typically do is another. Even just offloading some of the administrative paperwork for clinicians to admin staff might make a significant dent. Relaxing any bottle-neck non-essential bureaucratic requirements slowing down access to treatment or acquisition of new equipment and supplies.
Having said that, I also recognize that the ideas I just came up with in the last 30 seconds are just that: ideas off the top of my head, coming from someone with no actual experience in healthcare management.
Basically, my first priority would be to make an informed decision, and that starts with figuring out what I don't know, and filling in those gaps. Rather than uncritically insisting, quite emphatically, that medicine can be solved with a 30-day boot camp. Because, hey, if it worked for tech then it must work for medicine!
They asked for evidence. I did as much, explaining a very, very basic concept in medicine, "sterile technique," and how even that can take years to get right. And was told, in response, that I'm just imagining reasons to object. Evidentally, keeping tools sterile in medicine is something I just conjured up!
Perhaps you should take your own advice, rather than responding with personal vitriol directed at the users countering your point.
Maybe it's because you always immediately change the subject from the one other people posted, so you have no right to whine when somebody does it to you.
I'm still waiting for you to reply to the questions I asked in the thread that you kept trying to change the subject away from. When I wouldn't let you do that, and kept bringing you back on topic, you ran away because you'd painted yourself into a corner with glaring contradictions in the things you said, and there was no way you could resolve the contradictions except by admitting you didn't really mean what you said.
Because you're making a point of singling out every single reply in this thread that you disagree with, and making your objection about the user posting the comment rather than the comment yourself. Or broadly asserting that the parent comment never claimed points that were plainly written, and insisting on textual support. Your actual contrarianism is rather distracting.
Maybe I'm the first to bring up this comparison, but don't people deliver babies incidentally all the time (couldn't make it in time to the hospital, etc.) An event where I'm sure some would say only a doctor is qualified to handle it. And yet we still do what we have to.
Childbirth is a bodily function that the species is biologically predispositioned to perform. It will happen whether a doctor is present or not, to say nothing of the numerous possible complications. Ventilation is not a comparable analogy here.
No, and I'm not a brain surgeon either, so I suppose I can't claim you aren't qualified to perform brain surgery, using that logic. Better scrub up!
But if you're going to claim the contrary, I take it that you have a wealth of experience administering ventilation.
For the record, I've worked in fields tangential to medicine, including lab research for FDA trials and health tech. I may not be qualified to operate a ventilator, but I'm experienced enough to understand the technical skill gap between a non-invasive procedure and an invasive one. And ventilation falls into the latter category.
Don't anyone bother replying to this obvious sealioning troll technique. He has no intention of carrying out any kind of sincere argument, and his politeness is totally fake: he has no respect for anyone he's arguing with, he's just trying to waste everyone's time.
Of course he saw it, but he didn't like what he saw, so now he's pretending to have missed it on purpose, so repeating the facts he's ignoring won't make one bit of difference, and is just the two steps backwards he wants.
Notice how he always tries to repeat this same pattern in so many other postings, and don't reply to any of his attempts at trolling, except to explicitly point out what he's doing. And remember to flag him every time he does it, please!
He does have the advantage of being right though; I certainly didn't say anything like that untrained staff could administer a ventilator from a 30 day bootcamp. That is obviously stupid. Nobody in the thread did say that. The closest anyone came was pointing out it doesn't take 8 years to learn to administer a ventilator; which is uncontroversial. And that it takes less than 2 weeks to learn to press the buttons, which is also obviously true. Everybody knows they'd be killing people left and right proceeding like that left to their own devices.
Particularly my comment which seemed to spark something; it's a pretty basic fact that Ops Research people walk into situations where they aren't necessarily experts and optimise. That is a core part of the job. Every field is stuffed with experts who don't see how anyone could help them in their domain and they are generally wrong about the administrative trivia of organising a workplace. It doesn't even have anything to do with software. Ops Research is from mechanical engineering and factory optimisation.
I know bunch of doctors. I don't believe they work in an environment where the process has been mathematically optimised. They aren't mathematicians. That observation lines up very well with the "leave it to the experts" vibe of the responses here. They won't understand queuing theory for example.
Trolling by claiming to agree with people, and saying some things that happen to be right (while throwing much much more bullshit against the wall to see what sticks), and being insincerely and cloyingly polite, is still trolling, and classic sealioning behavior.
Take a look at his history. The first most obvious thing you will notice is how well the moderation system is working: so many of his postings are deeply downvoted (light gray text), flagged, and dead. But unfortunately he's still succeeding in wasting a whole lot of the moderator's and readers' time.
If you can stand to wade through his light gray walls of rambling incoherent text, you will see there is a consistency to how he writes, digresses, derails, pretends concern, contradicts himself, and regularly trolls and sealions.
As Jacques put it, "It's the online version of passive aggressive belligerence with a veneer of sincerity on top".
And when you try to pin him down on anything he actually believes, he retreats into his intellectual alt-right safe space, where it's impossible to truly know anything, and facts are a matter of opinion, since we live in a post truth society, and people all have their beliefs that they are entitled to, and everybody believes lies except for him, while nobody knows what he truly believes, but if you sincerely ask him, he derails and refuses to answer, and says you can't force him to answer your questions, because you're not the boss of him, and he's the victim.
Does that sound to you like the sincere conversation he claims he wants to have?
> Take a look at his history. The first most obvious thing you will notice is how well the moderation system is working: so many of his postings are deeply downvoted (light gray text), flagged, and dead. But unfortunately he's still succeeding in wasting a whole lot of the moderator's and readers' time.
That means that somewhere between 1 and 5 people don't like what he says. It is so consistent I actually suspect that someone has it out for him; there doesn't seem to be a particular link between what he is saying and the colour of the text.
> Trolling by claiming to agree with people, and saying some things that happen to be right (while throwing much much more bullshit against the wall to see what sticks), and being insincerely and cloyingly polite, is still trolling, and classic sealioning behavior.
If a sealion happens to be right I'm on the side of the sealion. Facts matter.
The issue with that quote is it ends in a question mark; which is typically used when people aren't entirely sure on a point and are seeking further information.
And it is a very fair question - given the number of people who are potentially going to asphyxiate this year it is reasonable to ask and have explained what the issues are surrounding ventilators. I don't know the answer to it, for example.
This is why I'm saying that mistermann had a point - questions aren't assertions. It isn't reasonable to interpret a question as an assertion. There isn't any evidence here of people looking down on the (rather lofty!) skills of the medical profession.
> "Why do people on HN consistently presume that they somehow know better than the experts?"
There's actually a surprising amount of anti-intellectualism on HN, as evidenced by the persistent "People don't truly need a CS degree to be a qualified software developer; it's just gatekeeping." rhetoric one sees.
lol this whole thread reminds me of the first time I dated a medical resident, carrying myself with similar confidence seen here, and quickly realized (after pissing them off with intensely ignorant statements a few times) I knew absolutely goddam nothing about medicine and how the human body works.
Overconfidence is one class of error. Imagining that a ventilator is a magic machine you can only operate with the sorcerous reagent of a medical degree is another.
Do you know how to operate a ventilator? Why do you think that volunteers couldn't learn to do it?
A scarily high percentage of comments in this thread are from ignoramuses adding nothing of value to the discussion. Some of those comments were written by you.
Look how radiologists work nowadays. They don't see their patients face to face. Everything except the decision making has been handed to someone else so they can be most efficient. That's the model a huge COVID19 ICU could work like.
Doctors don’t run ventilators. Respiratory therapists do. A respiratory therapy degree is a 2-year associates degree that includes basic training on physiology and biology. I’m betting that someone with an undergraduate degree in biology could learn the role in a few months of intensive training.
Doctors would still be responsible for reviewing the care protocol and making decisions on treatment, but one doctor could oversee many respiratory therapists, each caring for many patients.
It was a tongue-in-cheek comment. The point was that it takes more than a 30 day bootcamp to be more of an asset than a liability in a critical care environment.
HN denizens apparently seem to disagree, and believe that if you can learn some JavaScript framework in 30 days you can do anything in 30 days, but the world doesn’t work like that.
I think the push-back is that it's not black and white. If we end up in a situation where somehow we get 10x the number of ventilators and staffing becomes the limiting factor, you can bet that hospitals will get creative on how to operate them. You're right, pulling in people off the street is not the place to start (even 1337 Javascript coders). I would think you would start with trained physicians from other disciplines, PA's, NP's, RN's.
> About 4 years of medical school, and around 4 more years of residency training.
This is not universal in the US. You can do Bac + Med School in six years even there[1]. That’s the standard route outside the US’ former colonies and those countries with colonial cringe. Medical school in the UK and Ireland varies from five to six years with undergraduate entry. Graduate entry is four years like in the US, but pre-med doesn’t exist; you can start med school with a degree in dance[2]. Even in the US you can do med school in three years[3]
Most Covid patients die on respirators anyway, can a nurse do 90% of the job ("good enough") and ask a doc if the rest is needed? The other option is worse and I doubt USA can afford to have docs sitting for decades waiting for another Covid like scenario. Remember these ventilators will be produced and go in storage to wait...
I would think you could augment with other personnel - interns, students, volunteers - who are trained and who's only job is to watch the ventilator and monitor a patient. They do not try and treat a patient but call for help if the patient's condition takes a downturn or equipment shows a problem they have not been trained to address.
This is not general purpose training - but very bounded / specific notes.
That's got to be better than exhausting more vital personnel.
The numbers from Wuhan were something like 30% fatalities for those moved to ventilation. That doesn't detract from your point but does support why the path "make a ton of ventilators" is being persued.
Technically I should provide a citation and searched, but couldn't find it. I'm almost certain that I've read that wayyy more than 50% (prob 70% die) once placed on ventilator. Maybe because those ending there are already with one foot+ on the grave. The ventilator can save,say 30%, and also make us feel good "we did all we could," after all, we will all reach that point one day ;)
There is a small study / report released with 32 patients in Wuhan who were put on ventilators. 31 died.
I have not been able to find any larger case reports. Though on Tucker Carlson a few nights ago, a doctor on the front lines in NYC was interviewed and gave a similar report: If you reach the point of intubation and ventilation, the chances of survival is quite low.
A lot of these stats now coming out are going to be harder and harder to interpret going forward, regardless of the true numbers, as the media twists things around for their own political purposes. If ventilators turn out to be not the difference between life and death, even according to the raw stats, the media who wants to use lack of ventilators to blame one political party or another for the incompetency, isn't likely to tell the truth anyway.
I’m not a medical professional so hopefully someone more knowledgeable and confirm or counter.
From what I’m reading the treatment of COVID19 seems to require a pretty narrow set of practices. Mostly around monitoring, administering of medication, ventilation / oxygen and general bedside care. If this is true can we not cross train adjacent areas like EMT, army medics etc fairly quickly to provide care? They don’t even need to perform diagnostics.
Is that the typical setup for covid icu patients though? I imagine ventilators are used for all sorts of patients, some requiring much more involved care.
That's about as simple as it gets. This is a pediatric ICU ward, I just wanted a picture that shows you the essentials. It can get much more complex than that and not a whole lot simpler. Once you are intubated you are kept sedated (it's not exactly a pleasant experience) so you rely 100% on the world around you for your vitals and needs. Essentially you are in a controlled coma for the duration with all the difficulties that brings.
Is there any evidence that access to medical professionals is a bottleneck? Even after all elective surgeries and routine doctor visits have been postponed? All the stories I've been seeing from other Western countries that have already reached peak capacity say that ventilators, not medical professionals are the real bottleneck.
> It’s much harder to ramp up production of medical professionals.
and the fact that we think about "ramping up production" of "medical personel" leads the way to terrible industry-like education systems which emphasize cost-efficiency rather than quality education.
I think about this whenever I think about how many expert frontline healthcare workers we’re going to lose in the coming months, especially considering the state of PPE in the USA. It may not show up immediately in economic metrics, but we will be losing untold man years of training and expertise.
Another shortage is lack of ambulances to take you to the ventilators as demonstrated in NYC already as more and more drivers and personnel are already sick and not allowed to work
Once you are on a ventilator for covid19 you tend to monopolize it for 2+ weeks, hence the endless need for more machines
This conversation begins when the number of residencies increases. And that will not change until congress approves more funding for residencies. Until then, there will be no change.
That's a weak argument, in my opinion. I've commented on this in the past, but there's nothing physically stopping hospitals and other institutions with their own funding from opening of more spots. You can definitely get ACGME accreditation without CMS funding for your program, institutions just need to be willing to find other funding.
If only there were a nation, so far unaffected by the virus, with a large number of skilled medical professionals willing to travel to other countries and help. I'm sure if such a place existed, the US would be negotiating right now to get a supply of such medical professionals. And certainly wouldn't be sabotaging that country's ability to aid other countries /s.
Saying it is easy to ramp up machinery implies that it actually is... while your point that human capital is more valuable than tools is correct, ask yourself why a sophisticated pump costs 10k$ and requires a medically trained person to operate it.
There is a lot of money to be made by keeping these barriers in place, through legal, technical means and by limiting people’s access to “experts” that know what to do with them.
Is it though? Can't you train people on the basics of a single device as a sort of Tier-1 support with the ability to escalate to Tier-2 immediately? Governor Cuomo said in at least one briefing that they were considering training national guard troops to do exactly that.
The device he was referring to was a hand-driven bellows attached to a face mask, and he brought it up as a desperate, last-ditch scenario, ending his description of it with "No, thank you!" Though I think there's a good chance we'll end up there.
Those are a lot simpler and safer than a mechanical ventilator, which requires intubation or a tracheostomy, which you might say is highly invasive of the respiratory abstraction layer, and can cause correspondingly subtle and messy failures.
People who are experts in using one class of ventilators (ICU) are already being trained in using a different class of ventilator (anaesthetics), and they're somewhat concerned about this because of the differences in the machines. https://twitter.com/aroradrn/status/1244134454001635329?s=20
Your idea is to take a bunch of people who are not experts in ventilating, who have minimal experience with ICU vents, and give them a training course on ICU and anaesthetic vents and hope that they remember the difference and can work out the different panels, while exhausted, while in full PPE.
This is happening, but it's scary.
Your wider point - can we reskill a huge amount of the existing workforce to do a different job - is a good point, but that's already happening. Lots of people are doing jobs that they were not trained to do and they're doing those jobs with minimal re-training. This may help some patients, and it may cause harm to others.
I've been wondering if there is any way to improve this as well. Say we get the new ventilators but now we're short on people. You can't overnight train nurses, but can you get people just enough training for this specific task? Is there any inefficiencies in the process of dealing with these patients that can be improved? Can some of these tasks be delegated to less experienced people who can be trained quickly, while the processes that need in depth knowledge and experience can still be performed by the qualified health care workers?
Right, so it's a mistake to make ventilators, masks, PPE, all pointless in your opinion. Give up now we should.
The actual very interesting issue right now with ventilators is that there's companies in the US that make them and they say no one is ordering them. They cost around $25,000 each. Hospitals and states are sitting around waiting for the federal government to buy them and gift them to them, and whining that everything is the government's fault when that doesn't happen.
Documentation will be one of the biggest bottle necks. You can not do anything in the system without documenting every single item you used or action you have taken. It takes huge amounts of time. These doctors could increase the patients they see I would guess 10 fold if they didn’t have to document every detail. But it would be hard to bill without the details and for some things documentation is critical and important. In a triage situation however a lot of stuff could be ignored completely and focus solely on critical elements like lab values not that you used 12 pieces of cotton so bill that.
I always criticized the idea that “radical technology could exist but the competition buys it up” as a naive conspiracy theory.
It’s pretty remarkable that the government paid for this but somehow the international medical corporation can swoop in, buy the competitor who is threatening their margins, and void the contract.
Another line of inquiry to pursue would be why it took the government five years from canceling the Covidien contract to ordering ventilators from Philips.
It does not look like a regulation problem, but a contract breach: the buyer corporation should be held accountable to execute the contract as agreed, it bought the company with everything - assets and obligations.
The government often makes decisions about companies buying other companies.
If a company has a contract with the government, then the government should have (specified already in the contract, perhaps) the right to prevent the sale of the company (with some specific exceptions).
The primary problem here is that in theory, the government works for the people; but also in theory, the (publicly traded) corporations work for the shareholders.
But yes, even without regulation, the government should have made more effort to enforce the contract. Perhaps the key government people with the power to do so were influenced somehow... But even if the contract had been upheld, there's certainly no guarantee that the new big company would have put their best effort into meeting the original goals of the contract (especially if it was against their "best" (profit) interest).
We believe many things to be true, that are not true. And not only do we believe them, we passionately defend them!
I don't think many of us would recommend writing software on top of such uncertainty, yet we seem to think it's possible to do so with a society and economic system. Then we're surprised when it blows up in our faces every decade or so.
The surprised Pikachu meme seems fitting.
EDIT: To those who disagree, I'm rather curious to know the specifics of why you disagree. Do you actually believe that humanity, and each individual in it, has evolved to the point of something resembling omniscience? Perhaps we don't know everything, but that the subset of everything that we do "know", is absolutely perfect, not the slightest imperfection, however small?
Have our various societies and financial systems evolved to the point of near perfection?
And if it isn't that, then is it something else I'm off on? Just trying to get a better understanding of what the situation is here.
The short answer is, much of what we believe, both individually and collectively, is simply incorrect. In this case, my perception is that a person believed something to be untrue due to the idea having been labelled a conspiracy theory, and then after reading this story, he was less confident in the belief.
Generalized, we might state this as: the perception of high accuracy in our beliefs is illusory. Not only does this occur at the individual level, but also at the group level (see: religion, Trump supporters, etc)
I then compared that to the manner in which different people exhibit "unexpected" differences in insistence in accuracy/quality across different domains, demonstrating that the inner workings of this behavior can be counter-intuitive at times.
In light of this ongoing global pandemic, I am curious whether this "illusion of truth" phenomenon that psychologists suggest occurs within human consciousness may possibly have been a contributing factor to some of the perceived shortcomings involved in our response.
For example, as I understand it, Donald Trump seemed to believe that this pandemic was not terribly important, and the result of this was that the response from the United States government was slower than it could have been.
Similarly, prior administrations, I'm not sure going how far back, were also aware of the possibility and consequences of the outbreak of a global pandemic. It would have been possible at that time to make a significant permanent investment in nationwide infrastructure for stockpiling critical supplies, but for specific reasons not known to any of us, it seems like very few countries went forward with such an initiative. Not only in the United States, but many other countries.
Generally, I think it's fair to say that historic decisions related to pandemic response were less than optimal. Assuming this is true, it seems reasonable to speculate that a misunderstanding of risk was a contributing factor to the imperfect responses.
If we take a hypothetical example of two different countries, one with a brash, super confident leader, and the other with a much more restrained, cautious leader, one who is naturally distrustful of casual optimism and a culture of "don't worry about it", might these two leaders have had different perceptions of risk, and as a result made different decisions and taken different approaches, both during and in the years before an actual outbreak occurred?
I believe this is possible, and also that the magnitude of the difference may be significant, depending on the circumstances
And if that scenario is possible, might this phenomenon also occur in other domains, and if so, what might the plausible range of possible consequential variances look like?
Take the Iraq war as an example. Might it be possible that errors in perception of risk were a contributing factor in the decision to go forward with the war? Using a similar example to the one above, might a leader or society that insisted on a higher standard of certainty and trustworthiness of evidence have made a different choice on whether to proceed with a war? And if so, might this have had an effect on the amount of money spent as well as the number of casualties? I suspect that if the Iraq war did not take place, both cost and casualties would be significantly lower than they were under the scenario that actually did play out.
So what? Well...if we made better decisions, might we realize better outcomes? This seems both plausible and potentially significant to me.
If one assumes this is true, a question arises in my mind: should we perhaps consider collectively exerting additional effort towards the goal of making better decisions, and what are some of the things we could do in an effort to achieve that?
To be clear, I'm not suggesting we do such a thing at this particular point in time, and I'm certainly not insisting we do it. It's mostly just an idea I've had knocking around in my head for a while.
The only thing I can respond to your lengthy comment is: politics as we have it now is rigged in the favor of populist "leaders" that do what people want them to do, not what is the right thing to do. With "one man, one vote" the lower 51% less educated and intelligent part of the voters will elect the politicians that play their tune, even if the other 49% that are more qualified will vote otherways. In a way, it is the dictatorship of the stupid (no intention to offend someone, just math and basic psychology).
I found some of my father's school books from ~ 1960: that close after the war, it included lots of war-like information like how to use protective gear (not top NBC one, but how to improvise if needed), how to carry a stretcher, first aid, etc. Now people forgot about war, this is no longer in the school teachings and people lack self-preservation skills. If a country leader tells them to self-isolate, they will laugh and ignore until it gets serious and in hindsight they blame politicians. When you have no pandemic for 100 years you don't care about ventilators and ventilator contracts, you care about unemployment, taxes, football and the last iPhone models.
History is always forgotten because regular Joe and Jane don't read history and Einstein has a single vote.
> The only thing I can respond to your lengthy comment is: politics as we have it now is rigged in the favor of populist "leaders" that do what people want them to do, not what is the right thing to do.
I mostly agree, but I would replace "populist leaders" with something like "the rich and powerful". If you think back to before Trump's election, can you remember anyone complaining about the system being rigged in favor of the rich and powerful?
> With "one man, one vote" the lower 51% less educated and intelligent part of the voters will elect the politicians that play their tune, even if the other 49% that are more qualified will vote otherways.
I agree a lot with this also. Where you and I likely differ quite substantially is in the designation of who belongs in the groups "less educated and intelligent part of the voters" or "more qualified". I consider concepts like intelligence and qualification to be highly dimensional, where most people seem to see it as uni-dimensional (here I must speculate, because ideas like this seem to be a rather sensitive subject for many people).
> In a way, it is the dictatorship of the stupid (no intention to offend someone, just math and basic psychology).
I would absolutely love to see the math behind this, are you referring to a specific paper of some kind?
> If a country leader tells them to self-isolate, they will laugh and ignore until it gets serious and in hindsight they blame politicians.
This seems true enough, there have been all sorts of people on TV laughing it up on the beach with full knowledge that a global pandemic was underway. It would be nice if we could find a way to put some additional sense into these people's minds.
> When you have no pandemic for 100 years you don't care about ventilators and ventilator contracts, you care about unemployment, taxes, football and the last iPhone models.
110% agree here - it's true, and it is a very big deal, imho.
> History is always forgotten because regular Joe and Jane don't read history and Einstein has a single vote.
Yup. The interesting thing about that though, is that hardly anyone reads history. Take HN for example, I'd be surprised if even 10% of the people here would remotely qualify as "students of history", yet I suspect the percentage of people who consider themselves qualified to deploy phrases like "History is always forgotten..." would be up around the 90% range. Obviously I'm not referring to you here since I mostly agree with everything you've said, but I suspect I'm at least in the ballpark.
I forgot to tell: you are focusing on US (the Trump mention), I work in a US company (so I keep up with the situation there) but I live in Europe and I see the situation in the countries around me: it's full of populism, not "the rich and powerful".
I don't have a specific paper in mind for the math, but the knowledge from college with a major in statistics (and demography). It does not make me an expert, just a bit more qualified than most people.
Does anyone know the survival probability of a covid-19 patient once he requires the assistance of a ventilator? I have heard people mention it is fairly low but haven’t seen any figure on that.
Since you seem to be knowledgeable, if ventilating isn't a big-impact intervention, what's the point of flattening the curve? Is there some other intervention that hospital is doing that actually makes a more meaningful difference that can't be done at home?
what is so complicated about ventilators? Serious question as I don’t know enough about this. I see a lot of DIY posts that are probably not 100% the same thing but are they even close?
This opens up a bigger question too, is there such a thing as a path for open source medical devices to be built and certified and deployed? Is there a company that supports something like this? I follow Scott hanselman, a Microsoft employee who’s diabetic, and there is a big movement within that community to build open source artificial pancrea, using insulin pumps and software and such. Is there a play like that for ventilators? And other critical medical devices?
My wife is a doctor (I am not). I've been following COVID closely and discussing with her/peers. I'm not an expert (but feel I have an above average understanding, thanks to my wife)
> I see a lot of DIY posts that are probably not 100% the same thing but are they even close?
I have yet to see (though I haven't looked extensively) a DIY ventilator that has the fine tune control many doctors are suggesting are required for COVID patients.
My understanding is most of the DIY vents are comparable to emergency or transport vents. They'll keep a patient breathing for minutes/hours until they can be transferred to a proper ventilator. After a short period of time, you really need to transfer a patient to a proper ventilator to continue to support life.
Two big challenges with COVID patients in particular:
* They require ventilation for DAYS or even weeks. Over durations of that long, you really need precise control over a vent. A tech analogy is using floating point numbers for finance. Over a small number of transactions, a floating point number may be sufficient. Over time, though, the inaccuracies of floating point numbers will become apparent.
* Many COVID patients needing ventilation also have Acute Respiratory Distress Syndrome (ARDS). The simple explanation is their lungs are functioning so poorly that you can't simply stuff oxygen into them and hope it works. You need to be extremely particular with how you control breathing.
* Bonus, related to point two, many doctors are reporting using pretty crazy ventilation settings as a baseline. They're basically overclocking a CPU/GPU by default then hoping they can keep overclocking as CPU/GPU load increases (not fully accurate, but it's an analogy).
There is nothing complicated about air pressure/volume control loop. If $5 arduino can control a V8 engine (Speeduino) it can control a small air pump.
Partly this is a problem with jargon. When healthcare professionals talk about "beds" or "ventilators" they mean "the bed and all the staff needed for the patient in that bed", or "the ventilator and all the staff needed to put a patient on, and take a patient off, the ventilator".
And another simplified cheat sheet for people who use machines in one setting which are now being used in other settings, but it has replies from doctors asking questions that give some hints at the complexity: https://twitter.com/aroradrn/status/1244134454001635329?s=20
Then you have all the "human factors" stuff caused by machines having different layouts.
This is going to be a huge issue with the onslaught of different manufacturers.
I liken it somewhat similar to helping troubleshoot router/switch issues... yes at a high level they're all the same but, at the same time, each one has it quirks and peculiarities and even use slightly different nomenclature that make it a non-trivial exercise.
There is a narrow range of pressure where you're not damaging the alveoli from underpressure, but not bursting the lungs from overpressure. You need a mechanical scalpel, not a butcher's knife.
Honest question: is the pressure range actually that narrow?
People can survive at high altitudes, which will see pressure of 70% sea level (or less, especially when considering mountain climbing). Additionally, when SCUBA diving, something like 30 feet of depth = 1 atmosphere.
I feel like I'm missing something here. Any ideas?
Covid patients in the ICU probably don’t have healthy lungs. The people you’re talking about at those pressure ranges are probably all young, healthy and athletic.
I know a bit about scuba diving, and you absolutely are not supposed to go diving if you have a lung injury.
I would speculate that if you put a person with serious covid on a mountain top or 30 meters under the ocean it would kill them pretty quickly..
As you point out, the body can tolerate significant variation in absolute pressure, corresponding to the temperature, composition, and density of the gas you breathe.
The pressure that must be narrowly controlled in a ventilator application is the relative pressure: the difference between the absolute pressure outside the lung (in the room) and the absolute pressure inside the lung. This relative pressure is what does all the work --- mechanically opening airways and alveoli --- and could cause all the injury.
Scuba divers are at ambient pressure and breathe through demand valve regulators. Pressures inside their lungs are almost exactly the same as outside so there's no extra stress.
Increasing pressure with depth does increase work of breathing due to higher gas viscosity. Beyond a certain depth, divers can no longer ventilate enough to take in O2 and remove CO2. This problem can be mitigated to an extent by breathing lower density gasses such as helium. Occasionally hospitals even have patients with severely impaired lung function breathe heliox just to get better gas flow.
In theory it's possible to use a 2nd-stage scuba regulator as an improvised mechanical ventilator by partially blocking the exhaust valve with your hand and pressing the purge button. In practice it's unlikely to work, but if I was trying to rescue someone who had stopped breathing in the water and had no way to get them back to shore or a boat quickly then I might try it as a last-ditch effort.
Yes, it's pretty narrow. I've had double pneumonia somewhere in my 20's. Just playing a reed instrument (sax) was over-pressuring my lungs to the point that it led to more damage over time. And that's only a tiny little bit of pressure.
What’s the limiting factor there? The pressure regulation, pressure production, measurement accuracy? There’s open source ECUs that measure dozens of sensors at 1000hz+ and keep an engine perfectly timed using a $35 raspberry pi. Is this problem harder somehow?
How could we archive that? its not like almost disposably cheap actuators moving with 0.1mm precision guaranteed for >10K hours MTBF was a solved problem over 30 years ago (floppy drive). /s
They're really not very complicated; the requirements can be written out in a few pages. I'd say they're a bit more complicated than your fridge, but a lot less complicated than a car. Generally the primary barrier to entry for manufacturing medical devices is not their complexity but the onerous requirements of certification by the FDA. On the whole that's a good thing, since it means that properly certified medical devices are rarely built by fly-by-night organizations that disappear once they have your money.
In the meantime COVID19CZ created an open source version - https://news.ycombinator.com/item?id=22724130, crowdfunded the first batch of 100 ventilators, and they start producing them in the first week of April
They acknowledge the New York Times at the end of the article. Perhaps they licensed the content. I don't think that anybody aside from legal staff at the New York Times can determine if anybody was fully ripped off. If you have concerns about copyright and want to do something about it, you could report the issue. I assume that the New York Times is fully capable of hunting down violations without any help.
The site is much nicer than the New York Times. I'd prefer that the New York Times be banned, both for the paywall and for severe political bias.
Normally I use less emphatic language. However, I looked at the submission history for the site. Of 11 articles posted to HN, every one was a copy. They've copied from NYT, bgr.com, Polygon, FT, and Fast Company. That's a lot of "licensing".
True, they were nice enough to link to the originals, but for some reason the vast majority of blogspam sites do that. Only the very bottomest of the barrel do not. I assume there's a reason for this other than invariable last-minute scruples, but who knows? Maybe an HN user knows that business and can explain.
The paywall question is a separate one, and decided here as follows: if there's a workaround, it's ok; if there's not a workaround, we bury the submission. Users usually post workarounds in the threads. The result is that more or less everyone can read more or less every submission that makes HN's front page, just with varying degrees of annoyance. I think that's the right tradeoff. The annoyance is real, but HN would be worse without links to these publications. Paywalls suck (https://hn.algolia.com/?dateRange=all&page=0&prefix=true&que...), but this is the best we can do until the publication industry sorts itself out the way music eventually did.
All publications are biased. We're not going to ban the NYT.
Click-through-rates are not going to increase because people signed-up for a free account with an email address. Greater revenue comes from greater traffic. Simple as that. If every time I see an interesting link from the NY Times and try to read it I am hit with a modal subscription request, well, very soon I just stop clicking NY Times links.
The other side of that is paid subscription to these newspapers-turned-web-news outlets. My guess is this is a bad (or let's just say, non sustainable) approach. If these outlets had to survive on paid web subscriptions they would likely shrink severely or evaporate. There's a reason for which television can still garner massive audiences. Imagine if every single TV channel demanded a subscription or registration.
I’ve always said that governments should use our tax money to design and validate key health and infrastructure components and only outsource manufacturing and only to local businesses. Governments are so utterly broken and inefficient that they can’t do it.
However even if they produced a design now we have supply chain problems globally.
Edit: I seem to have stirred up capitalist defence here. To clarify: The government runs healthcare here in the UK. They have a responsibility for making sure there is supply of equipment available for us. This isn't some car pooling company that says "there's no cars available until next Wed", this is healthcare. And as for production, the government should have agreements in place with manufacturers to switch to infrastructure build out.
We've screwed up flood defences, energy, healthcare so far. Lets stop now.
> Governments are so utterly broken and inefficient that they can’t do it.
Mostly when your entire platform is that governments are broken so you do your utmost to make them broken to prove your point. All governments have issues, but there are many that aren't "broken" like the US, and more and more so the UK.
Have you considered that maybe broken inefficiency is not necessarily a property of governments in general? The local optimum might be to avoid having the government do things, but the global optimum is to fix your government.
If you look at history, I'm not sure it's possible for a government to get better. I'm not aware of any historical examples. Revolution can happen, but that means a new government.
They clearly work well enough they every functioning society on earth utilizes one. What is your counterexample in which a government-less society flourished?
But the government agreed to cancel the contract at the big company's request. I don't see how the deliverable being the design instead of the ventilator itself would have changed that.
If I had a government slush fund to develop a low cost ventilator, I would try to structure the payments in the contract to be based on milestones with concrete deliverables. Not a tenuous agreement to buy a bunch of ventilators at below market price (it's implied in the article that the sales to the stockpile wouldn't justify the project for the company).
There's of course a possibility that the government wrote the most aggressive contract they could find someone to work on. But I doubt that is what happened.

This story, if accurate, is simply an illustration of how low-regulation capitalism works. "Working as intended." Profit is the only motive, and thus as long as the company/investors profit, then it is a success.
The fact that national or global human well-being suffered is irrelevant (so long as we accept that capitalism (as currently implemented) is the right way).
Now, there's a strong likelihood that the government officials with the power to prevent the sale of the company, or alternately the power to prevent the cancelation of the contract, were lobbied (and financially supported in various ways counter to the benefit of the people those officials represent). Otherwise, it's hard to imagine the government just casually agreeing to abandon a project that was already demonstrated to be near success (and the outcome of which was already demonstrated to be important).
> Governments are so utterly broken and inefficient that they can’t do it.
Exactly. Which means we should not be depending on governments to do it. This is exactly the sort of thing that private startup companies should be doing, without trying to involve the government's bloated and inefficient bureaucracy.
> even if they produced a design now we have supply chain problems globally
For this particular crisis, yes. But not for the next one, if we start now.
There is no profit to be made in building up huge stockpiles of ventilators that will only be used in the event of a freak disaster. Government has to pay for such things, because no economically rational private investor would.
It was already a small private company doing the contract. Another bigger company (that was publicly traded and therefore operating with shareholder profit as the primary if only concern) came along and bought the smaller private company. This happens to start-ups all the time.
What does this have to do with "government's bloated and inefficient bureaucracy"? The only government failure I see in this story is that they allowed the sale of the small company to the big one, or that they allowed the big company to get out of the contract.
If the government had done it in house they could have succeeded.
The problem here was the profit motive. Cheep ventilators endanger profits.
It is a side effect of free markets (I like free markets) that big firms get bigger, get more market power, kill off competition then price gouge. Health is a bad bad place to have free markets as the incentives are almost all wrong (exceptions: E.g. running clinics as a service for state run health systems turns out to work well here in Aotearoa - but even that is under pressure from consolidation)
Nationalise the whole ball of wax. Use waiting lists not wealth to ration access. FFS the richest country in the world is heading to a health catastrophe. What a bunch of idiots!
> If the government had done it in house they could have succeeded.
Ok, so how do we get the government to do it in house, and stick to it long enough so that the stockpile is there when the next disease crisis happens, which might not be for another 10 years? That's five Congressional elections and at least two changes of Presidential administration.
Party politics is a separate shit show. It should be an elected council with no single representation. That would allow smaller, manageable policy changes rather than burn the entire universe every few years.
> Government is not congress, or a president. It is civil servants beavering away.
The civil servants work on what Congress and the President set as priorities. They cannot execute plans that span multiple Congresses and Presidential administrations unless every single Congress and Administration over that time period agrees to support the plan.
Yes, because three successive Presidential administrations and six successive Congresses supported it.
More precisely, two successive administrations and about four successive Congresses supported it. The third administration began to back off, as did the fifth Congress; then the sixth Congress, along with the administration, stopped supporting it--and the moon missions stopped. Despite the fact that a large number of civil servants were making cogent arguments for why they should continue.
> They built a horrifying arsenal.
Yes, because every President and every Congress since 1945 has supported it.
Healthcare is a much larger proportion of the economy than NASA ever was. And if you're trying to put up the US military as an exemplar of US government efficiency and competence, no thank you.
There's no "free market" in healthcare; it's one of the most heavily regulated sectors in the economy. It's a known side-effect of regulation that big and politically-connected firms are advantaged over smaller and leaner ones, market power tends to increase in lockstep with the regulatory burden, and a lot of price gouging becomes feasible that wouldn't occur in a more contestable environment.
Not only is health care regulated, it isn't even a market in the correct sense, because the people actually getting the health care services--patients--don't even know how much the services themselves cost. Which means that nobody is in a position to judge whether the services are worth what they cost. This isn't a market at all, it's a recipe for disaster. Which of course is exactly what we have.
The government tried, but then canceled the contract at the request of the big company that had bought out the small company they originally had the contract with.
Exactly. The issue in some sense isn't government, it's the corruption of government by corporations that have been allowed to become to big and to powerful, to the extent that the US Government itself has been deliberately defunded. (Sure, I know Government spending grows every year, but so does the money supply and corporate profits. Control for monetary expansion, and the US Government's portion of the economy has been steadily shrinking.)
> The issue in some sense isn't government, it's the corruption of government
Ok, so how do we keep the government from being corrupted? Nobody has yet solved that problem, and people have been trying for centuries.
> Control for monetary expansion, and the US Government's portion of the economy has been steadily shrinking.
The money supply is not the same as the economy. Government spending as a percentage of GDP, which is the closest estimate we have to "the size of the economy", has been growing, not shrinking.
The trick is doing that while still having some semblance of free speech, and allowing constituents to talk to their representatives about what problems they are seeing.
> Control for monetary expansion, and the US Government's portion of the economy has been steadily shrinking.
What? No it hasn't. It has kept pace with GDP since the end of WWII (prior to WWII it was much smaller), and the rate of GDP growth is higher than the rate of inflation. The size of government in the US has been growing continuously in real terms since before Eisenhower.
Really not even for this particular crisis. We can build more of something on a short timescale, it just costs more then. You have to build facilities you know are only going to run for six months and then be decommissioned, so you have to amortize their construction cost over half a year instead of 30 years. You have to build them on the double, which means paying a lot of overtime and buying land and raw materials without taking a lot of time to negotiate on price or worry about efficiency. But we could do it.
And then the ventilators would cost ten times more than they ordinarily do and idiots would accuse anybody trying to do this of price gouging. But it could be done. (Unless the idiots pass a law against charging more than the regular price during an emergency.)
> Why should hospital X buy 100 ventilators...just in case
Well, of course. That's what we're talking about, right? Somebody has to do the long-term planning for emergencies like this one.
I understand that most of us thought it was the government's job to do this long-term planning so individual facilities wouldn't have to, but this article shows that the government failed at that job. Unless we have some reason to think the government wouldn't fail next time, it seems like the only alternative is for private entities to do it.
But private entities can't do it, because the market forces them not to - those that the spend the money will be out-competed in the short term by those that don't.
> private entities can't do it, because the market forces them not to
Private entities don't have to be subject to the market. Someone like Bill Gates or Elon Musk could set up a privately owned company, not publicly traded, that would not be subject to investors' demands for consistent quarterly growth. Matter of fact, maybe that's what Bill Gates should switch his attention to from malaria.
The fact is, a private individual, or a small group of them, can have a longer time horizon than the government does, and a longer time horizon is exactly what is needed for something like this.
The government failed here but they are the only ones that can really prepare. A pandemic is as much as a threat as USSR, Bin Laden was, or China is, so just as they have these billion dollar planes they should prepare for Covid like situations.
"Companies submitted bids for the Project Aura job. The research agency ... chose Newport Medical Instruments, a small outfit in Costa Mesa, Calif"
This is the problem. Instead of allowing several companies to compete for a large order of new ventilators, the $ were given to one company to be spend on design not on the product.
No, that is specifically not the problem. The problem is that the company had demonstrated a working design and was near production... but then the wheels of finance (by way of publicly traded company) stepped in with a profit-only motive.
If three companies were all competing, there's absolutely no guarantee that each of those three would not have been bought in the same way. No large company would have gone for such a contract unless it had no other way to make money; there wasn't enough profit incentive.
I learned through a personal connection who was actually on the ground in Hubei (but not Wuhan) caring for serious but non-ICU patients that doctors and nurses in their ward outnumbered patients, and they were at capacity. The staff-to-patient ratio should be higher in the ICU. With an overwhelming number of patients you simply can’t care for them, whether you have the machines or not.
It’s relatively easy to ramp up production of machines. It’s much harder to ramp up production of medical professionals.
