I need your expertise. I'm on APAP for almost 3 months now and I'm comfortable with my mask and the machine by itself.
The problem is I still don't feel the benefits of my therapy even if my numbers are pretty good with an AHI below 0.5 most of the time.
Can you be a bit more specific about what you mean by you "still don't feel the benefits" of your therapy?
Are you still experiencing some of your pre-CPAP symptoms of OSA? If so, which symptoms?
How would you describe the subjective
quality of your current sleep? Do you get to sleep at the beginning of the night with little or no problem? Are you waking up a lot during the night? Or are you just not feeling much different than before you started CPAP?

But what fixed pressure I should start with???
Some people do sleep better with fixed pressure CPAP than APAP. On the one night of data that you posted, your 95% pressure level was 13.54. If that's pretty close to what your 95% pressure level runs most days, then starting with a fixed pressure of around 13 or 14 is a good guess. If you switch to fixed pressure I'd keep EPR = 2 at least for a few nights. It's best to only change one variable at a time.
But if you don't want to give up on APAP just yet, it is worth considering changing EPR from 2 to 3 and leaving the machine in APAP using your current settings at least for a few nights.
Quote:Also you need to know that I have a problem of swallowing air (aerophagia). My EPR is full time with a 2 cm H²O.
Switching to CPAP may or may not help with the aerophagia. I think you'll know whether switching to CPAP helps or hurts the aerophagia issue within 1-3 nights.
I will add that when I was on fixed CPAP pressure I had a lot more trouble with aerophagia than I had on APAP. But even with APAP, I still had enough aerophagia and other problems leading to sleep disruption that the sleep doc finally suggested a switch to bilevel. Auto bilevel is what finally brought my aerophagia under control.
So you might want to talk with the sleep doc's office. Mention that you've been doing this for 3 months with good numbers on paper, but that you still feel lousy and that you are still experiencing a lot of aerophagia. Ask whether it's worth being switched to a bilevel machine to see if that helps with the aerophagia.
