Any idea what's causing such low flow rate? - stevew77 - 10-01-2023

I have noticed occasional drops on flow rate. There is no snoring but the tidal volume in this segment drops to 206, SpO2 drops to 92%, and minute ventilation drops to 3.50. Any idea what's causing this, and what I can do about it. I was using an N30i mask at the time and sleeping on my side.

Whatever it is, the ASV is hammering you with the full pressure support it has available. You may be chin-tucking in a fetal position, but you're compensating a bit with a higher respiration rate. I think it's positional.
