I don't know how to operate a ventilator, and have zero medical training, but I'm getting frustrated by the comments claiming medicine is trivially easy. Even using a syringe or blood draw on a patient is something one needs certification to do properly. That isn't bureaucratic nonsense. Having worked with syringes and sterile technique, there are so many ways you can give your patient an infection or otherwise cause…
I am getting frustrated by the comments that miss the big picture. There are likely going to be lots of people that are going to die without ventilator. Now, who with any common sense and decency[1] cares if 30% of them are dying because the device was not used properly/broke/whatever if the only other available option is that 100% of them die? [1] Sigh... I know, I know. American lawyers and legal system.
I'm not saying the alternative is do nothing. But playing doctor because you think that you're reasonably qualified to administer a ventilator, then we're going to end up with, say 30% mortality rates from patients whose lungs were sucked through a ventilator tube because you guessed the wrong pressure. Or, more realistically, a terrible infection because you decided soap and water in the bathroom sink would be sufficient to clean the apparatus.
And then what do you suppose will happen after 30% of these amateur medical procedures go South? Are you going to throw in the towel, try something even more reckless, or decide that you need to get an actual doctor involved to clean up your mess? At which point, you've just added yet another case to the already overburdened medical system. And at a 30% failure rate, that would become a major burden.
There's a lot of room for action between doing nothing and acting foolishly (such as claiming a 30% mortality rate for botched medical procedures is a rational tradeoff). There are ways to help the situation here that don't involve magically becoming a nurse overnight.
