I have been studiously surveying my sleepyhead report and I noticed that the first 3 nights, my AHI was 0.8 average. However, the Mirage FX mask was strapped on tightly and I had sore nostrils in the morning. Leaks were moderately low (95% was somewhere around 9).
I loosened the mask the last two nights (based on a post I read here) and bumped up my pressure from 12 to 13. Believe it or not, my leaks actually went down, BUT my AHI shot up to 2.4 over the last two nights.
Questions: should I be concerned that my AHI has risen? Is it normal to see variations that large from night to night, or should I strap my mask down tightly again?
Is AHI 2.4 worrisome? Should I be striving to achieve the lowest score possible all the time, or is 2.4 "acceptable" (my diagnosed AHI was 88!)
