Resmed Aircurve 10 ASV: Central Apnea Not Relieved

I've been struggling since winter of 2023 to obtain relief from Cheyne-Stokes central apnea using a Resmed Aircurve 10 ASV. The sleep clinic recommended the ASVAuto setting with Min Epap 4, Max EPAP 15, Min PS 4, Max PS 14. On the very rare occasion that I get a tight mask fit, I seem to get some relief. However, most of the time I struggle. I'm attaching an OSCAR analysis screenshot for a nap I took yesterday afternoon. The mask in use was an Airfit F-30, medium size. You can see my breathing starts out uniform, but eventually mask leaks start to undermine everything, and my breathing becomes a ragged mess.

Does anybody have suggestions to improve my breathing during sleep? I almost always wake up feeling tired and drained. I've tried different masks, starting with the Simplus full face, the Evora full face, and Airfit F-30, F-20, and F-40 masks. I also tried the Resmed P30-i nasal pillows, but they require my mouth to be taped shut, and the tape eventually blows loose on the pressure peaks, ruining the seal.

According to your OSCAR you posted, you have no Central Apnea....You are having large amounts ofpositional apnea.

You can see positional apnea where either H or Oa events are clustered together. Getting rid of as many as you can will lower your AHI. Positional apnea can NOT be controlled by pressure changes or ANY cpap machine. You have to find out what position you are getting into and cutting off your own airway. Have you changed your sleep position? Sleeping on your back? Using more (or new) pillows? These things can cause positional apnea by chin dropping to your sternum and cutting your airway. Think of it of a kinked hose – nothing can get through – you have to unkink the hose…

IF you can’t make a simple change like changing to a flatter pillow helps then you will need a collar. I have a link to collars in my signature at the bottom of the page. It shows people who are not wearing a collar and the SAME person wearing a collar. There is a huge difference between the two.
