Resmed S9 detected unknown apneas but there are none on a graph in any software!?
#1
First of all, happy New Year and best wishes to all! Smile

And now to the point: this is beginning of my third month on S9 and this morning LCD on my Resmed S9 shows AHI 2.3.
I downloaded data in SleepyHead and ResScan and results are: in SleepyHead AHI is 1.57, and in ResScan, AHI is 2.3 (the same as on LCD). The reason for difference is in unknown apneas - machine detected them and calculated in AHI but neither SleepyHead nor ResScan shows them on their graphs!? I think that SleepyHead calculated AHI from events from graph so it gives smaller value because there are no unknown apneas there - but that is smaller problem - the thing that bothers me is the fact that either ResScan nor SleepyHead does not shows ANY unknown apneas in their graphs - but S9 detected them and calculated - and, looks like it did not marked them last night!?! Is this some kind of bug in machine? I had unknown apneas few times during last two months and they are normally listed in graphs in both programs - but last night was the first time they are not shown in any graph, but they are detected by the machine!

Detailed AHI values from ResScan and S9 LCD are:
AHI 2.3
OA 0.9
CA 0.3,
HA = 0.2
Unknown apneas 0.7

All values are the same in SleepyHead except unknown (unclassified) apneas which are 0 there.

I slept for 5 hours so 0.7 is almost one per hour - it is not small amount and should be shown on graph - but there are none...

Anybody had same situation? Or maybe my S9 starting to be "buggy" (I assume software is OK because both programs shows graphs correctly - so looks like there are really no data of unnown apneas written on SD but calculated in AHI in the same time)?
