RE: DD Therapy (Centrals?)
Thank you. I will try that tonight. I was told by my doctor that my sleep study showed 150 some events the night of my study. With around 15 of those events total being central. The rest obstructive. Not sure exactly that means. But I will say that the night of my sleep study wasone of the worst nights of sleep of my life. I couldn’t sleep with all of that equipment attached to me. So sometimes I wonder how accurate the study was. He also did say that those in-home studies will sometimes incorrectly flag centrals when they were actually obstructive. He wants me to keep after it without my current machine for a couple more weeks. He has bee now very responsive and helpful luckily. I honestly don’t really feel like I have gotten any real sleep since I started therapy so I am hoping that my bodybuilding is still just trying to adjust to the extra air. Thank you so much for your help

RE: DD Therapy (Centrals?)
time will tell. 15 ca vs 135 oa; chances are this is a case of treatment emergent pressure induced ca that will dissipate in time. here's hoping anyway!

RE: DD Therapy (Centrals?)
FWIW my sleep study scores were 124 CA to 24 OA. Call me ASV Dave. Comparison purposes the main goal here. Not an attempt of diagnosis either way.

RE: DD Therapy (Centrals?)
So the last couple nights have been better. I set my machine to cpap mode with a fixed pressure of 7.0 and EPR off. I am still having the issues with centrals although it is much better. I also had a glass of wine both nights, not sure if that helps or hurts my situation. But overall, much better. Do you think these centrals will continue to diminish with time or should I be changing any more settings. Would it help to show different graphs in OSCAR? Any help is appreciated. I am too happy with the lower AHI to go back to sleep this morning haha. Thank you!

RE: DD Therapy (Centrals?)
Im not really sure how to read this graph but my leak rate seems to look kind of odd. Let me know if you think that could be an issue. Thanks

RE: DD Therapy (Centrals?)
Looking at the graph the leaks are nothing to worry about in that they are less than 24L/M which Resmed flags as large leaks, unless they are waking you up

RE: DD Therapy (Centrals?)
Here (last chart) the leak rate is, of itself, insignificant but The spikes seem to match with a good number of CA events. These CA "events" I suspect are you holding your breath as you toss about a bit, thus the short duration spike of a leak from the toss and turn. Not an issue but I believe you can ignore those events.
Right click on the title of the leak chart and turn on the events overlay, That will repeat the event marks on the leak chart for easy comparison. A 2 min zoom close up may provide more detail that may prove out or deny my theory.

RE: DD Therapy (Centrals?)
as you know <5 ahi is considered treated. you've gotten your ca down to an 'acceptable' level. if your ahi remains stable, it might be as good as it gets. otoh, you have some flow limitations that might be eased by more pressure and some residual ca that might be eased by less pressure. if it was me, I'd see how this goes for a few days to a week, then continue to experiment with lower and higher fixed pressure until I found the best balance of oa and ca - which might be exactly where you are now but can't be sure until you rule out other pressures. wait at least a couple days between changes. if these are pressure induced treatment emergent ca (that'd be my guess), they'll dissipate in relatively short order.

We saw a bunch of Centrals in the data that were flagged as Obstructive. What take-home machine did you have? I had a "Zmachine Synergy."

My machine was the Philips Alice Nightone I believe.
