RE: Interpreting CA events
I agree, but pressure is currently fixed at 6 because the doctor wrote the Prescription that way and I am still early in the compliance period. I know how to change the mode but I don't want to appear uncooperative. I am collecting lots of data to show the doctor at our next meeting.
Zooming in on the flow graph, I see patterns that look like Cheyne-Stokes, which I am keeping an eye on.

I see - that makes sense. I had a similar concern when I first started, but my pressure range needed some work, and my DME told me that insurance didn't give a damn what I did to the settings - they only cared about usage. It's very cut and dry.
You could always call your insurance to confirm how they define "compliance." If they don't care about settings and your DME reports you as uncompliant, well guess what? You have the DATA on your SD card to support that you ARE! You can even generate the exact same compliance report that your DME would send insurance, using the ResScan software!

RE: Interpreting CA events
Even though your pressure is 6 and your EPR is set to 3, your Resmed machine will not go below 4 so, in effect, you have an EPR of 2.
The pattern surrounding your CA is somewhat reminiscent of Cheyne-Stokes Respirations. If it were me, I would bring this up to my sleep doc.

RE: Interpreting CA events
This morning (after the dog woke me at 530 wanting to go out) I never really got back to sleep. I drifted in and out for almost an hour and the graph shows lots of this Cheyne-Stokes-like pattern. So it may just be an artifiact of being half awake - I think I read that somewhere. Anyway, all of my apnea events, of whatever type, look a lot like this on the Flow graph, just of varying severity, which the classification algorithm sorts differently.
A couple months of data should show wether it is anything to worry about. Overall AHI is staying under 2 even counting these borderline events. I have been having mild sleep apnea problems for over 30 years (now that I know how to recognize the symptoms) so I am not too worried.

Since your AHI appears to be well under 5, the handful of centrals wouldn't be a reason to change therapy. At least, that's how I've (finally) come to understand it.
Hi tmoody,
For diagnostic purposes, central apnea usually requires more than 50% centrals AND
the number of centrals per hour >5.
