Why is your PS set to 8?   What do you have going on that would cause your doctor to suggest that?  

On your AutoSet all you should need is to set your min pressure to 7 to allow room for the EPR to work.

With a PS of 8 I suspect your doctor is trying to force all of your breaths. Barring some legit medical reasons for those settings, the doctor saying I said so isn't good enough, try the following.

These settings are intended to provide nearly the same therapy as your AutoSet

Mode: VAuto
Min EPAP= 4
Max IPAP = 15, only because I don't want you to freak out if I say 25.  The intention being to prevent significant pressure increases, and thus your aerophagia, by preventing events via proper settings.
PS=3, this is the big change you are currently using 8. The titration protocol is to start with 4.

Increasing the PS, the difference in pressure between inhale and exhale, increases the amount of waste products you remove from your system, specifically CO2 and it's byproducts.  Our primary trigger to breathe, simply put, is the need to eliminate CO2, not to intake O2.  When your CO2 levels fall below your apneic threshold a Central Apnea is triggered.  This is what is happening to you without question.  

Try the settings I suggested, they will feel much better, post your results and then we can help you fine tune it.

Hello Gideon, thanks for the reply. I didn't see your post until just after I seen Red's recommendation and make the changes on my air curve. I'll give those a shot tonight and tomorrow night give yours a try. I don't think my doctor has a clue. He looks at that one magic number and that's it. I was talking to him about  some of the data seen in OSCAR and he was like a deer in the headlights... I took a sleep test because my cardiologist (my 2nd cardiologist, the first let me suffer 2 years with sleep apnea and aFib) said I was too young to have Atrial Fibrillation. I think during the at home study I had about 11 OSA or hypopnea's per hour. After getting the cpap and using it for a while I started to open my mouth a couple times a night and realized I never knew what a real dry mouth is. When you can barely open your mouth because of the friction between your cheeks and gums.. Lol. I felt like a mummy. I asked my doc about a bi-pap and he said he doesn't think it will help because he thinks I'm a mouth breather... If I were a mouth breather I'd probably have been having the same issue earlier. I think I was subconsciously fighting exhaling against pressure. The bipap has felt better and I haven't been dozing off to find myself whistling. Thanks for the info!

How do you feel?
