Hello, this is an update for original post.
I followed the advice and kept narrowing the range of pressures and here is what i found out :
i'm originally a side sleeper, but through the night, (and video recording) i sleep on my back in many of the portions, so the original post screenshots, i believe many of them were on my side, i never checked for my position, so a pressure of 5, 6, 7 all seemed ok with no AHI because my apnea happens mostly on my back. but once i turned on my back, the pressure was not enough to keep my airway open.
So i started to increased the pressure each day, and i still woke up till i arrived sometimes i would increase the pressure in the morning because i was waking up at night with the lower setting.
it looks like even pressure 10.5 was not enough when i sleep on my back, so in creased to 11.5, and 12 and 12.5 till 13, and my body did not like that pressure, at 12.6 and 12 i was swallowing air, burping air and my cheeks were inflated(chipmunk) and was waking up so often because of that. so i can not tolerate pressures over 11 i think, i'm going to try 11.6 again tonight.
it looks like the best solution is staying under maybe 10 and be able to sleep on my side all the time, i have been reading online about positional therapy but with my memory foam mattress it looks like tennis ball won't be enough.
Could you please update your advice with the new information ? should i increase the range of my APAP to lets say 9 to 12 ? (remember i'm sensitive to larger pressure difference range), any WORKING solution to keep me on my side ?
P.S: forgot to mention that hard horrible sleep in this week as well, with all the things waking me up.
thank you
