CPAP is used by the NHS for Covid-19 to try and avoid the need for invasion ventilation, even in the ICU (examples [1], [2]). I was in intensive care for 10 days, and was on CPAP (100% oxygen) for the majority of the time.
Yep - I was told fairly early on that if I didn't start improving on CPAP in a reasonable timeframe, or I worsened at all, I would be ventilated (SpO2 90% with occasional dips to 88-89% on CPAP, SpO2 was 78% on admission; arterial blood gases were monitored, but I've no idea what the readings were).
