Could it be CSDB?

After two weeks on the Bipap machine my my AHI is averaging 13.5 ( AI not available on display). Five months prior to this on the ResMed S8 auto Vantage the average AHI was 11 with an AI of 2. Negligable leakage. 95 th percentile pressure was 12
The Bipap 90% pressure average is 12/9. Full Face mask and total Leakage average is 30 L/M. My original sleep study said AHI of 12
Could this persistant AHI be a symptom of CSDB ?

What did your sleep study say? Did it mentione centrals?
Could just be the pressure isn't right for you.

Would need more info - get copies your PSG and Encore readouts.

GUMBYCT,
My Doctor did not provide me with the details of the original study only the bottom line . I have an appointment in late December and I'll ask about the centrals . I have asked for detaied printouts of my ResMed data in the past but the Dr decided to move me to bipap and did not provide them. I'll ask for an encore report and discuss a pressure change at that time. I do not intend to make pressure changes on my own. Thanks for the response
