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
