Newbie here, I wanted to get some insight on my experience to date. I was diagnosed with severe sleep apnea 1.5 years ago with an AHI of 37.9. During my split-night test, a pressure setting of 8 cmH2O was able to get my AHI down to 1.1. (See results below).

I only recently discovered CPAPtalk.com and sleepyhead, and so I've been pouring over my data. The average AHI over the first 15 months of usage was 7.85. The lowest AHI I've ever seen using these settings was 3.27. Here is a day where I got above average duration of sleep and the AHI was 13.91.

I discovered through this forum that although the Rx was for a fixed 8 cmH2O, I could change the setting and that there was an auto function. Right now I have it on auto, with a min of 9, max 20, and am still getting an average AHI of 7.5.

One thing that I am noticing in the data is a higher CA rate than during the sleep study, which won't respond to the CPAP, but I'm not sure why I'm getting this. Overall, I'm not sure if I feel more well rested than before, but I'm sure much of that is due to overall lack of sleep (demanding job, new parent, etc.), and I'm working on sleep hygiene. I've used the F&P Eson mask (what was used during the initial sleep study) and the Philips Nuance Pro nasal pillows, and with both I do sometimes find myself fiddling with it in the middle of the night. I have yet to do a follow-up sleep study since the initial split-night. I know 7.5 is better than 37.9 but I think I can do better. Perhaps I'm just jealous of all the 0-1 AHIs I see posted here, and I figure that was once possible with me. But I'm also weary of doing too much dial-a-wingin too. Any suggestions? Thanks.
