@JV - your min 5 EPAP is like if I had a start pressure of 6, seeing that your PS=1. My machine type counts pressure by IPAP, and EPAP + PS = IPAP. Congrats on AHI of 0!
@ASJB - Sorry to hear you are still uncomfortable with the current level of well-being. As it happens, the AHI you are experiencing is also suboptimal. There are some patients consistently under AHI of 1 and still have unrested feelings and insomnia. It is safe to assume there is something else that is at play in those cases.
I have done many little adjustments that were intended to get me consistently below AHI of 5, but I have been only mildly successful. In my case, the feelings part worked out well, so I don't feel I need to hurry through the process. This week I had 4 nights under 5, and a weekly average of 4.82. Last week I had 3 nights under 5, and a weekly average of 5.07. Three weeks back I had 6 of 7 nights under 5 and an average of 2.54. So I am only about 60% successful.
I think there is high potential that PaytonA's comment may be more to the point in your case. Hypopnea (as the machines record it) seems to be directly related to flow reduction, not to obstruction. Why you have hypopnea is still in question. To me, the results you have shared suggest to me the hypopnea is an indication of non-OSA. For this reason, your idea of going to CPAP of 9 seems like a great place to start, or similar to the retired guy's suggestion - trying a band of 8 to 10 cmH2O with an EPR of 2.
A screen shot of a recent night with flow and pressure (and I would add FL flow limitations to it) would help us answer the great hypopnea question better.
Hope you soon gain the success in well-being you need and deserve.
