I'll keep that in mind when reading my results for the night. My pressure settings are 8.0 - 15.0 and my EPR is set at 2. ...

Interesting idea. I hadn't thought of trying it.
Thanks, I will give it a try!

...And I do feel a little better. However, my average AHI is still running at about 7.5 with most of the number being Hypopnea events. My AI is rarely over 2. For example, last night my AHI was 10.5 but the AI was only 1.9 and the night before my AHI was 5.4. So, why does it flucuate sooo much or is...
