Replying to @paulg
This isn’t a deviation from what’s been done in WA and other hospitals since the beginning. Vast majority of patients recover after 5-6 days of nasal cannula 5L-6L O2. Proning is a relatively recent shift, but try telling old people they need to be face down for days.

5 or 6 liters/minute is ordinary oxygen supply; "high flow" can be 60 L/min. And that recomendation, and proning, and keeping ventilators at low pressure so as not to damage lungs, were all in Zhejiang University guidelines released more than a month ago (in fluent English).

Oh, and if you want to get the benefits of high flow oxygen without spraying virus all over the room, improvise a rebreather: https://yarchive.net/blog/oxygen/
