What I have read is that unlike typical ARDS cases where the lungs are failing, full of fluid and the patient can’t breathe, that Covid 19 patients can often breathe fine, and don’t have a lot of obvious lung damage, but their oxygen levels are dropping to dangerous levels, perhaps because of something that covid 19 is doing to blood vessels in the lungs that prevents oxygen uptake. One doctor likened it to high altitude sickness.
What they are suggesting is to put patients on oxygen or low pressure ventilation first.
