Hospital ventilators are not simple devices.

No because medical equipment salesmen sell them. The basic operation
is pretty simple tho. You are just replicating a fireman squeezing a
bag. Is the $100 one the greatest thing ever, probably not but if it
keeps the person moving air through their lungs, that is all you need.

I would rather have a $100 home made ventilator that works than just
sit there wheezing, wishing a $30,000 one was available.
