Someone linked me to this a few days back:

It explains how they pressurize the lungs to try to keep the alveoli open and why that's very problematic, even when it is only short term. It is so problematic, they sedate people on ventilators so they won't pull the tubing out.

It sounds just really gruesome and like a brute force method that can't help but cause serious problems for delicate tissues if you use it for more than a fairly short period of time, which is the norm but is not how it is being used for Coronavirus cases.

Oxygen delivery is a complicated thing and I think taking a mechanical approach when mechanics may not be the actual problem is likely misguided.
