Hi all,

I am new to this forum but, have been on CPAP for a little over than a year. I am a 38 year old male. My diagnosting and titration sleep studies revealed only severe obstructive apnea (AHI = 52) and my prescribed pressure is 7 mbar. I am using airsense 10 in APAP mode (pressure between 4-7.2). The 6 month averages for my obstructive apnea index and CA index are 4.52 and 2.87, respectively. However, for about a month I have seen an increase, with a weird pattern, in my device reported centrals. Specifically, because of our baby I have to wake up once or twice during the night. Until about 4 am when I wake up for the baby, my CA index is usually less than 3, but when I go to sleep again after 4, till the morning (usually 7:30) I see I get many centrals (CA index becomes 8 or so). I know the device is not as accurate as the real sleep study and I sometimes realize it even mistakenly records centrals at times when I am awake, but still seeing centrals this high makes me worried. I attach some screen shots from the last night. I am going to see my doctor in a month but I really appreciate your opinions as well. Thanks!

IF you have EPR turned on, then I would turn it off.

This alone may take care of that. The other thing is that this is occurring at the very end of the night. This is a somewhat normal phenomenon where sleep looks good throughout most of the night and then can just fall apart just prior to awakening for the morning. It doesn't happen in everyone like this, but it happens enough that it's definitely a "thing."

Your pressure doesn't seem crazy at all, so I wouldn't expect that to be a problem either. I don't see your EPR value, but I suspect that is where the problem is.

Thanks. The EPR is set at 1 and in the "ramp only" mode. Do you think it would be of any help if I completely turned the EPR off? I have also observed that I usually have less CAs of this kind when I sleep through the night without interruption.

Also, can you tell from the screen shots whether the CAs toward the end of the sleep appear to be real or they are a result of my moving while sleeping?

Thanks diamaunt - interesting!

Sorry to divert the thread, but I need to throw out this:

I'm struggling to understand my own situation (crappy sleep despite low AHI after starting with the CPAP. CA in the range of 50%-60%). Doctors haven't been of much help, they just look at the total AHI and pat me on the shoulder. I never considered that also low CO2 levels might be a factor, so this idea might be far out: Is it possible to "get used to" high CO2-levels (through my years of undiagnosed apnea), so that my assumed current reduced levels now make it difficult for me to rest?

My EPR-setting is 3 - it sounded like a good idea to me. I will start reducing it gradually now.

Sorry, that's meaningless. That could be 1 a night, or hundreds.

Since EPR is on only in ramp time then turning it totally off won't do anything for those late in the night centrals.
And that was assuming that EPR was a factor in those centrals which it can be for some people but not all people.

Have you watched the videos here to help you decide if those CAs/centrals are real asleep flagged events or awake/semi Awake/SWJ flagged events?

Has the machine ever flagged any of that breathing as CSR/PB?
