My numbers have been good, almost always less than 1 AHI. But other than a couple of nights in the past 6 months, I wake once or twice a night and don't feel refreshed in the morning. So, after reading numerous posts here, I made a few changes:
My old settings were 8.6 EPR 0. With those settings in the past week (7 days), I totaled 1 OA, 6 Hypopneas, 3 Centrals and 7 RERAs.
Flow limit 95% was around 0.14
Flow limit high between .23 to .30
Wanting to decrease my RERAs and Flow Limit to see if that would help, last night I upped my settings to 9.4 EPR 3
I didn't sleep well, and had:
4 OA
0 Hypopneas
0 Centrals
1 RERA
I was surprised to see the big increase to 4 OAs in one night given that I raised my pressure. My flow limit numbers were nice and low 0.04 (95%) and 0.14 (max).
Perhaps my EPR of 3 dropped my exhale pressure too low and that caused the apneas?
Any thoughts and recommendations would be greatly appreciated. Attached are screenshots showing the period around each of the OAs.
