I started using a Resmed Airsense 11 in January 2024 after receiving a pAHI of ~20 using an at home test. The first few weeks I had the machine I was using an F30i mask and found I was generally feeling better. Over the same period of time I had a head cold, and the extra moisture actually seemed to be helping me to breathe better at night. It all started to go down hill after I recovered from that head cold. And since January I've tried multiple masks (F30i, P10, P30i, F20, F30, F30i), chin straps, cervical collars, and pillows of different sizes and configurations.
In March I finally went to a sleep clinic for a full polysomnogram and daytime MSLT. The sleep study found I slept fine using a full face mask (note I do not have the results but I'm working on getting that report) and the MSLT did not indicate another disorder such as narcolepsy. Following that study, my doctor did set my PAP to constant 5cmH2O, as on APAP (5-20cmH2O) he felt it tended to stay towards a low pressure and thought it might help.
The problem is I continue to feel tired most of the time. On days my AHI is below 1 I tend to feel OK, but above 1.5 and I have hypersomnia, brain fog, etc. Looking at my data in OSCAR I see that most of my apneas are central. I've tried disabling EPR both on APAP and CPAP but it hasnt made a difference (EPR currently set to 1 at 5 cmH2O). Below are links to data from the past several nights as well as a closeup of some of my CA events (also attached):

The other thing I notice is that I have some residual flow limitations, but I dont know if they're significant enough to impact my treatment. I do tend to be congested; I've tried flonase, Xlear - which is pretty good - and breathright strips, which all help but never allow me to breath fully.
This is all to say, I'd welcome help, both in understanding my data and how I might be able to use it to improve my treatment and to help talk through things with my doctor.
