Can Palatal Prolapse be treated with CPAP

I have both AirCurve and AirSense machines. This results are from modded firmware on an AirSense 10 machine so some Oscar stats may be wrong. minPS was 2 and maxPS was 7 which Oscar is showing as N/A while Max IPAP should not be shown at all. Given the modded firmware I would not call this an Oscar bug, although it would be nice to have fixed if possible. So far I've used this firmware for about two weeks, machine behaviour makes sense and the graphs do look reliable.

I usually sleep with higher EPAP of 5-6 and see palatal prolapse waveforms few times every night but not expiratory flat waveform. While trying out the ASV mode I lowered EPAP to its minimum of 4 to minimize the max pressure of the ASV=EPAP+max PS. No apneas with EPAP=4 which is OK but the low expiratory pressure may cause my usual palatal prolapse waveforms becoming flat expiratory limitations.

Pressures were stable 6/4 across 12 minutes so this flat expiratory flow could be reproduced with regular fixed 6/4 BiLevel likely even CPAP=4:

You can use OSCAR to make the zip file. Go to Help->Troubleshooting-> Create zip of CPAP data card. Put your user name in the filename and upload it to Gideon's Drop box: https://www.dropbox.com/request/6VeFzBXa4qZ37EgphL5b

Done.

RE: Can Palatal Prolapse be treated with CPAP
I don't know if this is relevant at all, but I did an amusing experiment awhile back where I used my cpap to record me singing, and to me this looks sort of like the characteristic shape of PP. Here's the picture:

So expiratory flow limitation looks intriguingly like singing?

(For anybody who has ever sung in a choir, at least half of choral direction is the director yelling "NO BREATH" when you really want to breathe in the middle of a musical phrase. I have half-seriously wondered if in those REM-sleep apneas maybe I'm dreaming that I'm singing and not supposed to be breathing...)

So is the flow being limited in the vocal cords?

Looks like an Airbreak machine. I don't believe Oscar completely supports that mod.
