One of the reasons we worked out we could get people through without ventilators was because we ran out of ventilators. And people with COVid are being vented for 2 weeks plus. A normal time (and a time that would minimise Kung damage from a vent) would be several days.
But if someone has saturation’s in the shithouse, they’re going to die. Lack of oxygen (Hypoxia) in the blood is many many fold more common than severe thrombosis or whatever else was suggested; and the answer is right there - if the oxygen isn’t getting to the blood it’s because the lungs are shot.
If we have enough gear, we put someone in ECMO to solve the gas exchange problem.
Lung damage severe enough to do this is caused by the effects of the disease, not the ventilator
As far as I know nowhere ever ran out of ventilators, not even in Lombardy. But I sure saw that claim made a lot of times back when people thought that would happen. Spent a lot of time pointing out the authorities were denying it'd happened too. I concluded it's very easy for people to mix up "we think this is about to happen" with "this has happened".
Lombardy was utilising operating theatres and had ICUs and trauma bays full (70-80% is full because you have lost lost of your surge capacity), using the vents in all these areas.
There was a shift to NIV because once you have no vents you let people die
