Now, two months using CPAP, my AHI is considerably below 1, usually about .2
Question: For fun I'm looking at my data in SleepyHead. In the attached image, there are several 20 minute periods when my mask pressure drops significantly.
I'm assuming these are part of the normal sleep cycle. Is that right? Are they REM sleep or something?
What about the pressure drop during the two RERAs? Related somehow?
Are there other patterns in Sleepyhead data (either pressure or other parameters) that make for interesting reading for someone with a general interest in the field?
For example, I can see how fast I fall asleep. And I can see that my sleep breathing is shallower and faster than my waking breathing.
But, what else might be fun to spot?
