Thank you for the detailed replies, guys! After reading some of the other comments here, I had a sneaking suspicion that adjusting my pressure up from the prescribed settings was causing the CA's. I adjusted my pressure down to min 7, max 12 (from min 8, max 14) last night. While I had a lower overall AHI (5.75 vs. 7.73), I again woke up around the 4:00am - 5:00am mark with a leaking mask and a feeling of being unable to breathe.
Further, later in the morning (around 6am), I noticed myself waking up gasping.
I've attached screenshots (removed the chart, shrunk the calendar!) below. I'm going to try a fixed pressure setting of 7 or 8 tonight and see what happens. Separately, I noticed some oddities with my "Resp. Rate" chart. I believe you referenced this elsewhere Sierra with a comment along the lines of "40 is panting" - I'm spending what appears to be significant time above 15, ranging up to 45... any idea what the heck that is about?
I've been using my AirSense 10 since last Thursday. I'm using the Dreamwear FFM, but I believe my FF cushion should be a small instead of a medium. Working on getting that resolved. I only have data on my SD card from last night, will continue to review nightly results using Sleepyhead.
I remember waking up at/around 5:00 with a large leak. I could make the leak go away if I tensed my jaw. As soon as I relaxed it though (as if sleeping), the leak would return. I tightened the straps and it seemed to go away. This basically happens every night - I'll wake up to a leak and have to tighten the straps on the mask.
My in home sleep study AHI was 18 and then my second in home sleep study was 12.8. The doctor prescribed settings of "5 to 12", although I bumped it to "8 to 12" because the first night I kept waking up gasping for more air. I feel better than I did a month ago, but I'm nowhere near where I want to be. 36 year old male, BMI of 28 but that's because I have an athletic build (and sub 15% bodyfat).
What should I adjust based on the data below? What am I looking for? I'm seeing a lot of "clear airway" apneas, is that because I adjusted the pressure?
