I am not sure where to go next. My sleep tech set me up on 5-15 which you can see an example of attached. Regardless of pressure, I spend at least 2 hours before I wake up having arousals every 30 seconds to 2 minutes, usually when I'm dreaming as I will wake up fully many many times. This also happens at a pressure of 18-20 which I'll attach next. I seem to have an arousal after a bunch of flow limitations? My tidal volume also goes down before an arousal, sometimes into the 200s.
Background about me:
Female, 163cm, 65kg.
Mild OSA, severe during REM and "possible nocturnal hypoventilation" which hasn't been further investigated yet.
Have 2 neurological chronic illlnesses, 1 connective tissue disease
My illnesses can cause respiratory muscle weakness although this has not been confirmed for me yet.
Low arousal threshold - I wake up to any and everything
I barely slept during my level 2 home sleep study so I'm repeating it next month.
Any help on where to go next would be appreciated. Thanks

Myra
Charts at 18-20 added. Same problem. My thoughts are I need to try a bilevel?
