Help IDing this "crescendo–decrescendo + pause" flow-waveform

[BeatZeps]

Hi everyone,

I’m digging through my oscar data and stumbled on a flow-time plot that looks odd. 
Breath-to-breath amplitude ramps up, peaks, then ramps back down.
At the end of the downslope there’s a brief pause / near-apnoea (basically flat flow) before the whole cycle starts again.


I do struggle with fatigue and sudden awakenings, using currently CPAP (but will switch soon to BiLevel/ASV).
AirFit F20
Pressure 5.8 - 8 APAP
ERP 3
No Alcohol/Drugs/Smoke
Athletic, Male, 41
Non allergic rhinitis controlled with Nasonex/daily Netipot/Breathe Right Strip
Asthma as child
PTSD
Side sleeping

Is this the classic Cheyne-Stokes respiration (CSR) pattern?

Thanks

If this happens every 90 minutes or so then it could be REM. How often do you see it in your data?

[BeatZeps]

It can be every 10, 15, 30, 60 minutes.

Switching to bilevel or ASV might help this. 

You do have some CA's spread out across your nightly sleep.  

Reducing EPR can help lower CA's; but at the same time increase flow limitations.
