DIY Ventilators? Not Unless There’s a Zombie Apocalypse

The part about the DIY ventilator being just as likely to kill the patient as the virus is what really makes the entire idea somewhat suspect.

What would actually work would be to force medical companies to (temporarily?) give up any patents they have in ventilators, or going all the way and forcing them to open-source their designs, so that anyone can see what we need, how we need to build it, and who would be able to do it, and when. But let's talk about DIY ventilators instead, eh?
