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.
