Anyway, the ventilator hardware is relatively easy to make, a gas pump, reduction and humidifier, plus a few hoses. 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.
