Medtronics' "open source ventilator" bullshit PR

If it ever gets that far with me, I'd rather take some barbiturates and die than be sedated and connected to some botched together ventilator systems.
First scenario, I die painlessly and quick, second scenario, I probably die as well, just much more slowly and painfully. And if the guy which sedates me fucks up, I wake up as as an oxygen deprived retard, how fun is that.
Same happens, if the homebuild ventilator craps out.
The only thing I would trust is with with old school iron lungs.
Requires nothing but some old barrels, some valves, very basic electronics and couple of radial compressors from like old vacuum cleaners.

In that case please do make sure others are aware of your wishes so that you don't tie up equipment and efforts that could be used to give someone else several more years/decades of life. Of those who end up on ventilators it sounds like a majority of them do recover after a few weeks, it's not something where they end up tethered to a machine for the rest of their life.

Interesting video on why most of the low-cost ventilator projects are a waste of time :

There's an identical thread on eevBlab as noted above.
Medtronics has a problem: Their customers want more devices than they can make but if they spend money on capital investment, the plants will be overcapacity when this debacle is over. Worse yet, hospitals will be flooded with ventilators and the market won't recover for years. Medtronics could possibly run additional shifts (if possible) but expanding capacity through capital investment is a money losing proposition.
So, to prevent backlash when they refuse to increase capacity, they pick a design that they probably don't care much about and open it up to the world. "Here, build your own" and "leave us alone".
Furthermore, it's not clear that Medtonics' suppliers can deliver the components at an accelerated rate. If they can't, it's Medtronics fault for not making more units. Nobody is interested in excuses. So, give away a design and let the other builders worry about the supply chain.
Releasing the design was a good move. It takes the heat off Medtronics and makes them look like a responsible corporate citizen. "Hey, we gave away a perfectly good design, some company just needs to step up and start building!".

some schematics for a unknown type no-name breathing machine
go back to the first invention of the medical device type respirator or breathing machine or iron lung,
and work forward until you get to todays design behind the curtain of property law.
this is were you need to step back and re-design to the best of the knowledge you have.
an all new design of medical device type respirator or breathing machine that is in no way
triggers a patent bomb or is as legally free of ........
if you was stuck on a desert island and your life depended on having a medical device type respirator
and lets say you had all the resource to build it. reliability and safety are important.
