RE: changed pressure question
So it looks like positional has creeped back in? I have been sleeping on my side. Can side sleeping cause this? Maybe rolling onto my back?
So the best option is to use a soft collar? If so, where to purchase?
Should I use 1 or 2 pillows?
So frustrating this started after a year.

The new Soft Cervical Collar wiki is in my signature links. We are not concerned with what you buy, and it may take some experimentation to find what works best for you. In general, 1-pillow should be enough to support your head and neck comfortably. Excess height can cause the neck to flex which is the root cause of most positional apnea. Chin-tucking can occur on your side as well as your back, so the soft collar addresses both.

Thanks. I ordered one to try. Just really frustrating this started out of the blue again. Had it in July and now. Not sure what changed.

So this is with a Soft Cervical Collar.
It still looks like positional, right? Any other ideas. It seems random, some nights it happens, others it does not.

RE: changed pressure question
I should review your thread before commenting but for now: I'm not sure the collar has much effect on ca clusters. I'd be looking for other things. your flow limitations aren't bad at .04 and .33 (95 and 99%-tiles). have you tried lowering and/or turning epr off and/or a fixed pressure? have you been able to determine if your ca is 'native' vs treatment emergent (did you have much ca in your sleep study?).

To me it looks like REM based CA’s rather than positional especially if the collar does not change anything. Looks like you need an ASV or turn off the EPR again

I ordered the collar based off or recommendations here from it being positional related. Not a big deal if it does not work. Had to try.
I turned off EPR and it did not work well. It gave me aerophagia (think that is what it is called.
I can try a fixed pressure. Maybe 9.5 or 10?
I had zero CA's on my sleep study. It seems treatment emergent. I have always had a few looking back over the software, a few here and there, nothing like this.

So this could develop that quickly? The first 7 days of September my AHI averaged 1.94. The next 6 days it was 12.4.
Would a fixed pressure be better? I tried turning off the EFR and it didn't do so well. I will turn it down to 1.
RE: changed pressure question
Central Sleep Apnoea can be consistently inconsistent, try 1 EPR we need to look at trends over time our target is an AHI of less than 2
RE: changed pressure question
The "best" way to turn off EPR on an AutoSet to maintain the current EPAP is as follows
Min Pressure = current_min_pressure - EPR
Max Pressure = no change (adjust later if needed)
EPR = off or 0
