Re: CPAP journey starts but still high Central Events

I started recording myself with an infrared camera recently, including timestamps on the video. I've been trying to correlate CSA events from the charts with the video that I record overnight. It's hard for me to do proper interpretation but I did notice something. I realized that I have a lot of hypnic jerks (involuntary muscle contractions or twitches) of my legs, arms and head. Those result in arousals. After each such, I usually turn slightly but I also take a deep breath right after that movement, followed by a long pause immediately after which is (falsely I believe) marked as CSA! Almost all of those that I tracked on the last night's video were such. My O2Ring does catch some of them, but not all.
I'll try a few simple things:
* Start taking again magnesium before going to bed
* Move my gym workouts in the mornings/noon
* Potentially add L-Theanine before bed too
Additionally. I started double-taping my mouth to ensure good seal and I finally managed to stop the leaks. They seem to happen when I sleep on my back and my jaw must be opening. Now I look like a chipmunk with nuts in my cheeks. As a result my SpO2 is much more stable.
Code: Select all
Min Med 95% 99.5%
No tape, no CPAP 81.00 94.00 96.00 97.00
No tape, with CPAP: 88.00 95.00 97.00 98.00
Double tape, with CPAP: 93.00 97.00 97.00 98.00
Porous tape, with CPAP: 91.00 96.00 97.00 98.00
As an aside: sadly both the ResMed and the O2Ring cannot keep proper track of time through the night. I could not find a way to set the time of my ResMed. I can only compensate in OSCAR (not in SleepHQ) but this is not enough because as the night goes on the time skew changes. For the O2Ring I can set the time and do so before going to bed but then it seems to lag by 5-6 seconds in the morning.
