There is nothing natural about using a CPAP.

Think about what happens if you vomit while wearing a full face mask. I suspect that is even worse.

Using mouth taping was the breakthrough for me in using a nasal pillow mask.

I have had my best luck with a down alternative pillow that I got at Costco. I find it gives and does not push back. The other thing that helps is to sleep with the mask off the edge of the pillow. A satin pillow protector seems to help some too. Lets the mask slide around better.

It sounds like things are heading in the right direction.

I find the biggest factor is the amount of time I sleep. If I sleep 9 hours I pretty much use all the water (AirSense 10). If I sleep 6 then there is lots left in the morning. Room relative humidity is going to have a lessor effect. Dry air, especially if the humidifier is in Auto is going to use more water.

If the mask is too tight it can crush the nasal pillow cone which can make noise and make it harder to breathe. I also find with the Swift the exhaust flow has a very high velocity. If it blows against the bed covers or clothing it can make a lot of noise.

The are a few tricks to getting used to and using the P10 mask. First, make sure you have the right size of insert. If you use an insert that is too small I think it goes too far into your nose and irritates the nose. I would suggest the largest insert that still seals is the best. I also find if you use a 1% hydrocortisone cream on your outside of your nose where the mask contacts it, it can help you get used to the mask. Put it on in the morning, but at night when you wear the mask. And, it is not for long term use. It should only be used for a week or so until you get used to the mask. The P10 should come with some clips that can be used to tighten the mask straps. That can help some in keeping it on your head.

The basic answer is that a standard Auto CPAP cannot address central apnea well, if at all. It may in fact make it worse. Can you give a little bit of background on how you got into using a CPAP? How were you diagnosed? Was central apnea identified during the sleep study test?

I think low AHI is only one piece of the puzzle. But it step in the right direction, once you can do it comfortably.
