I have been on APAP since November 2008. I have only "missed" one or two nights using my machine since starting, and those were because I was staying with my dad in the hospital. So, you can say I am very diligent about my therapy. I am also very involved in it as well (have to be becasue I have not seen or heard from Dr since I got the results of my study and my machine). I check my numbers regularly, and have modified my settings based on the numbers (originally set at 7-13, now at 10-13.5).
When I first started therapy I was maintaining an AHI of 6-8, and running near my max pressure almost all of the time. After several months I increased my minimum pressue and my AHI dropped to 3-5. After another few months I raised my max pressure .5 and my AHI dropped to 2.1-3.5. Now, several months later, my AHI is fluctuating more that I think it should - it has gotten as high as 6.5, and as low as 2.8 in the past few weeks.
My questions are: 1) do you see a problem with minor modifications to my pressure(s) since my Dr is not an active participant in my therapy? 2) should I be concerned about this recent fluctuation in my AHI? 3) could this simply be related to a new mask? (never had fulctuations like this before with a new mask)
