The thing you’re missing is these new RTs wold not just be treating COVID-19 patients. There are tons of people who will need ventilator therapy because they were injured or sick and they would have gotten injured or sick anyway. These are people who can be saved with proper treatment or injured by improper treatment. Barotrauma and lack of tidal volume have implications beyond simply alive or dead. We need people but we must make sure they can actually provide adequate treatment.
