I am relatively new here, but an avid follower of the board - most valuable info I can find anywhere.
I have been monitoring my Sleepyhead data, concentrating on AHI data, which has mostly been coming down. Last night I had an AHI of around 1 (yay!), but did not sleep too great. When I checked my RERAs, I noticed i had 55, mostly coming in two separate hour-or-so blocks in the night.
Upon close examination of the events, I became confused about how the machine (or SleepyHead, I don't know which) decides what is an RERA. I have annotated the screenshot below to show my question - why isn't the circled area a RERA?
I looked at a number of event times, not just this one, and there were a number of other examples.
As well as the above question, should i be concerned about the increase in RERAs. Is this a meaningful number? Even though this was just a one time thing. I will of course monitor as time goes on.
It is my understanding that the PAP machine looks for a particular flow pattern that is typical of RERAs. At least that is what was reported when I asked the question,"How does the machine score a RERA?".
In answer to your question of why one pattern was scored and a similar pattern was not, I am somewhat clueless. I have looked at your traces and nothing I see makes sense to me yet.
The FL graph shows flow limitation; FL is also evident in the "flat top" of the air flow graph.
