If my AHI was limited to just the OA and HA it would be pretty good.
I would have guessed the CA's to come during high pressure periods, but looking at the graphs they are everywhere.
More frequently around the median pressure, but also at low and high points.
Settings:
Pressure 10-15 EPR 2
(except first night was 6-12, second was 7-14, had to search a little to dial it in initially since I had nothing to go on)
(also opened the top range to 18 last night to see how high it needed to go, but it went over 15 just one time and just barely)
Humidity was auto (4) the first 3 nights.
Changed to 6 (out of 8) for the last 2 nights. (helped with dry mouth)
Tried EPR 3 (vs 2) last night, but it takes too long for the pressure to come back fully after an exhale.
Have to prolong the inhale unnaturally long for the switch from exhale to inhale pressure to complete.
It was very noticeable. The breathing sensation and also the mask rising and falling with the pressure changes on each switch.
I'm going to lock in at 10-15 and EPR 2 and ride it out a while.
Possibly tighten the range (later) to 10.6 to 14.2 to see if a narrower range helps with sleeping better and mask seal.
