Hi I am not sure if I am having real CA emerge or if there is something wrong with my settings. I am inclined to suspect it is the settings, because I have used CPAP for 2 years and have not seen many signs of CA in my reports. My typical AHI is 1.5 but last night it was 4, and my sleep was very choppy.

I've been traveling to Japan and here for 6 nights now. I had 3 great sleep nights (AHI less than 1.5), 2 bad (AHI 2.75), and then last night which appears like a disaster relative to my historical sleep results.

For the last month, my setting has been APAP 8.5 with pressure relief of 2, and this has worked pretty well for me, including my first 3 days in Japan.
Over the last 3 days however, I started to see more CA emerge as part of the AHI report, so I've been trying to modify the settings to get rid of them to no avail. I reduced pressure from 8.5 to 7.5, leaving pressure relief at 2. Then I changed it to pressure relief of 3. And finally I changed pressure from 7.5 to 9 with pressure relief 3.

None of these setting changes have worked well for me. I've had an extremely tough time getting to sleep. As I am trying to fall asleep I will actually notice what seems like it might be a CA - a shortness of breath or almost what might seem like a missed breath, and this will wake me up right as I am dosing off to sleep. For this reason it took over 2 hours to fall asleep, and is part of the reason I bumped pressure to 9 hoping that maybe extra air will help me not miss any breaths.

Having slept for 9.5 hours last night, I still feel terrible and have a slight shortness of breath even after I wake up. Any ideas on what is going on here and what setting changes I might consider making? Should an AHI of 4 affect me this significantly too? I feel like I can't do anything today.

Attached are my sleep reports from last night which includes some highlighted CA as well as CA right before dosing off (and then I took the mask off because I needed to calm down as I was unable to fall asleep).

Your CAs are insignificant. They occurred when you were preparing to get up or trying to get to sleep. They were clear airway events.

So in this case is there any solution. I feel like crap so trying to figure out if there is anything I can do to better my odds of a good night sleep.

You probably have an elevated AHI *because* you're not sleeping well...

The CAs are insignificant, that means there's nothing that needs to be done about them, they're not disruptive of sleep at those minuscule levels, assuming they're not just post arousal/sleep wake junk.

Just FYI I ended up going to the Dr to check for asthma. I used an inhaler yesterday and went to bed my AHI went back down to 1.3 and I had no CA instances. So it seems like you guys were right.

Thanks for taking a look
