Welcome to the forum Old82!
The CA's being reported are based (usually) on the premise that you didn't breathe for 10 seconds or more. You need to analyze your sleep data to see how long your not breathing to better understand what is happening. I sometimes have many CA events during a night's sleep only to find they lasted 11 to 13 seconds. As far as oximeter readings, it will probably be easier to obtain a CMS-50D+ or CMS-50F oximeter than finding the oximeter module that fits your CPAP. These models have recording capability for overnight use. The only thing to keep in mind when using these oximeters is they only record one continuous session. This means that once you start it for the evening, don't stop the recording until the next morning. Otherwise it will overwrite any previous data once the record function is restarted.
Could you briefly explain cms-50d+ And cms-50f.
WELCOME! to the forum.!
To treat Central Sleep Apnea, (CSA,) an Adapt Servo Ventilator, (ASV,) machine is used.
Hang in there for more answers (and a better explanation than I could give you,)to your questions and much success to you with your CPAP therapy.
@old82 - central apneas might also be caused by past and present opiate use. Check or ask physician about the medications you are on. And, do an internet search for 'opiate induced apnea'. good luck, and also please indicate what your normal or average AHI or RDI is.

No, no opiates. My ahi reports run between 3 and 8 and my central ai runs between 2 to 6 which brings me to a basic question about these "i"numbers which you may be able to help with. Does the i in ahi and total ai and central ai mean average per hour slept?
If so, isn't this a very misleading number? For example if my morning report says central Ai was 5 for 8 hours of therapy for that night but virtually all of my central apneas occurred during a one hour period early in the morning like during rem sleep this could mean I'm having very damaging central events over a short period of time that isn't reflected in an "average" number..correct?
