r/UARS

Background; snoring for years, not overweight but neck is large from sports + small(er) lower jaw + hard to breathe from nose + tongue tie. Waking up with headaches and started having panic attacks so saw sleep specialist, highly likely I have some form of sleep-disordered breathing. Waiting for sleep study results to come back.

Trying my dads emergency AirSense 10 (APAP) for a night; min pressure 4 max 10. Is this flow rate normal? Or does it indicate UARS? Chat is telling me my breathing is limited, then I compensate with a micro arousal, followed by a breathing pause. I have many of these throughout the night, but only AHI of 2. Have a few obstructive apneas as well.

Any help or advice would be much appreciated.

I just keep removing the mask at night I just dont know whats wrong with me... Nd yeah I tried ps of 7-8 as well but I got central apneas...Can anyone tell is the graph good or there are problems there if yes what should I do to fix it.. nd why m i removing the mask after 2-3 hrs

I’m currently using a ResMed AirCurve 11 VAuto. My AHI is usually under 2, leaks are essentially zero, and obstructive events appear well controlled.
What I’m trying to understand is something I repeatedly see when I zoom into my flow rate. My breaths progressively become smaller and smaller, sometimes reaching almost no airflow for around 10–11 seconds, and then breathing resumes with larger breaths.
I’ve seen essentially the same pattern on different PAP settings and even on my previous Luna bilevel, so changing pressure/PS hasn’t made it disappear.
I’m not assuming these are central apneas from the PAP graph alone, because the machine can’t tell me whether respiratory effort continues during the low-flow period. I have an in-lab sleep study coming up that should help sort that out.
Has anyone here had a similar pattern despite a low treated AHI? If so, did your sleep study determine whether it was obstruction/RERAs, central or unstable breathing, sleep-stage/arousal related, or something else? And did you ultimately stay on bilevel or move to another therapy such as ASV?
I can post SleepHQ zooms if that would help.
