I have been struggling with keeping my CPAP therapy consistent. It feels like I find settings that work great AHI 1-2.5, waking up feeling okay, not perfect, but okay. Then all of a sudden, without any apparent reason, I start seeing an AHI of 5-7 and wake-up feeling truly, horrific with extremely high level of brain fog and dizziness that last throughout the entire day. I am currently using a full face mask, Resmed Mirage Quattro. As this could appear to be positional apnea I have tried a cervical collar in the past, which did help my AHI, but had a few days of waking up feeling the worst I ever have, I fear maybe it was putting too much pressure on my arteries in my neck? Don't think that possible, but I woke up feeling very *BAD* and didn't think I had it on that tight.
One thing I notice which I have no explanation for and can't find any information regarding. The vast majority of my events I have are CA events, I would say 90+%, often clustered, and when my pressure is starting to decrease. I never get them at peak pressure while hitting my max after a small OA or flow limitation, always somewhere on the decline of pressure in which the pressure is decreasing, I get several. It's like a flow limitation or small OA sets it off. This is a bit contrary to what I think I know about high pressure causing CA's due to C02 flushing? As I show in Night #2 example. I have tried lowing my pressure and keeping the pressure minimum and max fairly close together, this does help AHI most days, but again I get an odd night that my AHI is around 5 with a lot of CA events, and I wake up feeling absolutely dreadful. I did use a smartwatch that actively monitored my Sp02, and it looked fine, lowest of 94%. So I have no dang clue! I do believe how I feel when I wake up is linked to how many CA events I have. No, an AHI of 5-7 isn't severe, but wow! When I wake up, it feels worse than If I didn't sleep. Seriously.
Looking for any recommendation that can help me find some stability in my treatment. I have tried so many different things and feel like I am failing. At this moment, I actually feel on an average basis I would be better without using my CPAP. Never feeling okay, but never absolutely dreadful, I have found this when I don't use it. Any recommendation would be highly appreciated. I do want this to work.
