The bad sleep is characterized by (a) I felt bad the next day, like sleeping with someone playing a loud noise in the room all night, my head couldn't focus during the daytime (b) I had a much higher AHI that night (4.0) relative to other nights (around 1 - 2) and ( c ) A Cheyne Stokes Respiration (CSR) for 15 minutes. Here are the stats:
Below is attached a screenshot of the charts. I see that:
1. There was some mask leakage in the last 30 minutes more than normally
2. Just prior to the mask leakage, there is a cluster of CA (clear airway) events
3. Just earlier to that at around 4:45am was a 15 minute span of CSR
Note:
- I only woke once that night. No eating, due to the effect of the Trazadone.
- Before sleep I did eat a vegetable protein weight loss shake my wife had bought, chock full of Vitamin B's and Chromium, something called Garcinia cambogia and various other vitamins, minerals. Spooked that it caused the bad sleep I stopped eating it. I did have a small amount of the shake only one night prior with no effect. No other changes in food, liquid or environment.
- I have taken Trazadone for 6 nights since then and every other AHI averages about 1.3 (between 0.7 and 1.5) and my sleep is good.
- I just reviewed two months prior in OSCAR and there is some CSR on Dec. 25th that lasted about 5 minutes (AHI 2.7). And on Nov. 11th for 20 minutes (AHI 4.8), Nov. 15th for 15 minutes (AHI 5.5), Nov. 16th for 42 minutes (AHI 7.6). All the other days back to Nov. 1st had zero CSR.
- I didn't see any leakage on those CSR days but they have much higher AHI.
- During CSR, OSCAR indicates a lot of CA events.
- I have noticed in the past that if I have a longer nights sleep, more than my usual 7.5, I will get the bulk of my apnea events in the last hour or two.
- For each of the days listed above, the CSR occurs about 30 - 60 minutes before I wake. Each is in a long segment, like 3 - 4 hours where I haven't woken.
- My mask pressure on those days peaks at about 12 cmH2O.
What causes the CSR and CA events, are they causing my really bad head that day, and what can be done, are they a big concern?
I've been told in the past that unless you have heart or other serious issues (I have none) to ignore occasional CSR, but in writing all this up it seems clear that the CA events during and or the CSR pattern is causing me feeling really bad the next day, at least on Jan. 15th, and probably the Nov. nights with the higher AHI's, but it depends also on the duration of the CSR and if I had enough total hours, etc.
I can upload more data if needed. Here's one screenshot from OSCAR, hope it's readable and sorry if it was the wrong or too much data:
Thanks!
