Just so you'll understand what you are reading. This is real fancy talk for saying people who are respiratory compromised with low oxygenation, but are maintaining their CO2 (not elevated due to less oxygenation) can use the high-flow nonrebreather mask on the floor and not tie up ICU beds and staff.

Because they are able to ride the wave of admits they can forsee who is going to need ICU. There is a window of time when oxygen starts to drop and the rest of the numbers hold. Hi-flow masks buy time.
