I don't think you have to apologize, the only reason people are downvoting you is because this guy hasn't moved outside their home with his house.

He was at home, his wife was taking care of him at this point. He was in and out of the hospital. Not sure on any details beyond that.

No need to apologize. So I didn't mean to say that the ventilator itself somehow killed him (although it kind of did and I'll explain later). But you're correct that being paralyzed on a ventilator(in his case about 2 years) leads to chronic infections and other problems. His injury was caused during a night jump where he hit the ground and his head was pulled in either toward or away from his chest. If I had to guess I think he unexpectedly hit the ground and when his helmet hit the ground his nightvision pulled his head towards his chest. The injury resulted in a transected spinal injury around C2 or C3. I was able to intubate him there at the scene of the accident and we flew him out to a hospital. He survived and like I said before lived for roughly 2 years on the ventilator as a quadriplegic. He was constantly fighting chronic infections in his lungs and was likely going to die at some point due to those infections. What ended up happening though is that his ventilator actually malfunctioned during the night and he basically suffocated.

I was in the military and even with all our checks and safety people still died, one I personally attended to who survived but was paralyzed(and eventually died due to being on a ventilator). And another who died in training after taking through his riser lines. Civilian skydiving is perfectly safe, like everything else you can be as safe as you want but accidents also happen.
