I'm a 33 year old guy who was diagnosed last year with an AHI of 17, mainly hypopneas and obstructive events. No significant oxygen desats were noted, and I confirmed this several times at home by sleeping with an oximeter. My oxygen keeps above 95 at all times. I do have to say I only slept for like an hour in that sleep study, so they probably pieced everything together to make my diagnosis. My prescribed pressure was 7 cm H20 fixed, but I opted to get an APAP just to have the option of changing it to an automatic pressure.
So I started with the APAP last week. My mask is the Resmed P10 and I have it set to a pressure of 7-14 cm H20 with EPR on 3 and humidity on 4. Haven't really felt a massive difference in my sleep quality like most people who write about it online. Maybe a slight difference. The only thing that did change is that I no longer wake up with a pounding heart and headache (although this morning was a little different, I think I had a veeeery slight headache). I also seem to dream a lot more. Before, I never dreamt during the first part of my sleep (first 3-4 hours). Now I do seem to do that.
My pattern of sleep has been the following for the past 3 years orso: wake up after 3-4 hours of sleep, then try to get back to sleep and wake up every hour/40 minutes. It's exhausting. I THINK that this is because the first part of sleep (first 4 hours) is deep sleep with little REM sleep. The last 4 hours is more REM sleep, and this is where most apneas occur to my knowledge. But Unfortunately CPAP hasn't helped this for the most part. Which is unlogical because according to Oscar my apneas are all but resolved wearing the mask. Except for one night last week were I seemed to have slept 6 hours on end, which is unusual for me. But since starting 2 weeks ago I've stuck to my old pattern unfortunately. And I my sleep remains unrefreshing for the most part.
So I've looked at oscar and mainly the AHI is below 1 (except for last night, where it was 1.19), and I don't have many obstructive events, mostly centrals. How can I get rid of those centrals (if possible?). Is there something that I could change or try to attempt to combat my early morning wake ups and REM sleep fragmentation?
The forum won't allow me to post pictures as I don't have 4 posts, but here is a link to a picture album with my Oscar screenshots: https://imgur.com/a/V2ycBja
