Where do the data flags come from? - LookingForACleverHandle - 08-24-2023
Setting the stage, in one of my other posts, I noted that the OTHER (unnamed) site flagged CA with the F&P Sleepstyle Auto, where OSCAR did not. I was SET STRAIGHT (gently) that OSCAR was where the development was, and that the CA flag would be in the next version of OSCAR.
As it is a F&P proprietary "feature, the SensAwake flag must be generated by the F&P Sleepstyle Auto and is passed in the data.
From this I infer some flags are passed in the data, and other flags are derived by OSCAR. Some machines provide more data than other machines. I assume most, if not all of those additional flags exist in that particular machine's data.
Where I'm going with this...
I occasionally exhibit patterns that look a lot like (and may very well be) Cheyne-Stokes patterns. Oscar flags these as a combination of OA and H events; the OTHER site flags the same patterns as CA and Hypopnea events. SensAwake flags are not present.
Now I wonder what flags are derived, and which are embedded in the data. Of course, that varies by machine.
Down to specifics, does the F&P Sleepstyle Auto detect and pass Cheyene-Stokes flags, or whether it is (or something that another machine would flag), or whether that analysis and flag can be derived?

First, the use of the term, "Cheyene-Stokes" is more appropriately called periodic breathing. The reason the "other" site is displaying CA data is because the OSCAR team has rewritten the code for the upcoming release, and the other site downloaded it from the OSCAR repository.
