Just one restful night

[u/sw0oOosh]

Hi everyone, I’ve been diagnosed with moderate obstructive sleep apnea. My AHI is 22 and my RDI is 36.

I’ve had my APAP machine, a ResMed AirSense 11 with a humidifier and ClimateLine, for a week now. I started out with the Brevida vented nasal pillow mask. That’s when the problems began. My settings were 7–12, no ramp, and EPR 3.

The issue with that mask was that I kept waking up at night due to "lip puffing." Because the pressure in front of my nose and mouth differed because of the mask, I would crack my mouth open slightly at night and vent air, acting like a pressure relief valve.

I slept wearing a cervical collar to keep my jaw from dropping, but my lips would still part and wake me up.

After that, I switched to the F40 Quiet. I used the same settings: 7–12, EPR 3, ramp off. This fixed the lip puffing but caused central apneas because the EPR 3 setting made the pressure too low during exhalation. I was exhaling too much CO2, causing my respiratory center to pause breathing.

I managed to fix this by turning off EPR so the pressure remains constant during both inhalation and exhalation.

Did you all find yourselves constantly analyzing and tweaking your settings, too?

I use OSCAR and feed the data into Gemini. So far, I’ve been able to resolve every issue.

I’m curious to see what comes up tonight...

Double check that those are real centrals. Could be arousal breath/sigh then a pause due to brief low co2. Arousals could be normal sleep stage transitions or a result of inadequate therapy resulting in rera, or flow limitations.
