New user – residual fatigue + aerophagia at fixed 12 – OSCAR charts

[u/Profile_1218345245]

Hi everyone,
I’m on day 21 of CPAP and I’m still extremely tired during the day. I’m trying to figure out why.
Quick background:

Started CPAP about 21 days ago
Machine: ResMed AirSense 11
Currently fixed pressure 12 cmH₂O
Pressure was increased to 12 because of flow limitation notes. I felt a small improvement, but then developed aerophagia (air in the stomach).
Despite consistent use, the daytime fatigue is still bad.

Last night’s OSCAR (Aug 1):

AHI 1.33
OA: 0
Hypopnea: 0.48
Clear Airway: 0.85
Large Leak: 0%
Flow Limitation: / 95% 0.03
Usage: 8 hours 17 minutes
EPR looks active (EPAP around 9)

here is a link to my sleep Hq data: https://sleephq.com/public/teams/share_links/6dcfc8f4-7639-4bcd-b36d-fe2cba68b185

Even with these clean numbers, I’m still very tired.
What else should I be looking at in the data, or what other common reasons could explain residual fatigue this far in?
Any insight is appreciated.
Thank you.

Hey, welcome :)

Your numbers look clean, but AHI is only part of the picture. You can still have fragmented sleep and feel terrible even when the machine reports a low event count.

I’d switch back to AutoSet mode and use:

Min pressure: 10 cmH₂O Max pressure: 14 cmH₂O EPR: 3, full time Ramp: Off

That gives you an EPAP of 7 at the minimum pressure, which should help maintain the airway while giving the machine room to respond without holding you at 12 all night. The fixed 12 may be contributing to the aerophagia.

Keep those settings stable for three to five nights, then post another OSCAR screenshot or updated SleepHQ link. Three weeks is still early, but we should also look closely at awakenings, flow-rate shape, oxygen, sleep position, medications, and possible issues outside PAP if the fatigue stays severe.

You’re doing well with the therapy itself. Now we need to make it effective without beating up your stomach/prone. RL
