We are talking about negative pressure mechanical ventilation. Positive end expiratory pressure is just one way of splinting open alveoli. Maintaining recruitment and V/Q matching in ARDS can be achieved in multiple ways, including negative pressure mechanical ventilation.
- JshWright 7y agoInteresting, I'd be curious to know more. My understanding of NPV is that it's primarily useful in cases when the lungs are generally "functional" and some other issue is preventing adequate ventilation.

Literally your granddad's CPAP sleep apnea machine is (almost?) good enough, if it has tuned oxygen intake. I would wager intubating actually makes most problems worse in case of damaged lungs, but with low odds only. The real problem will be getting actual oxygen (concentrators are not free) and people to tune the system.
