I now am awakened more often at night due to my new circumstances but suddenly I am seeing AHI=0 nights coming in groups every several weeks. I have no good explanation for this and I have gone back to the mask and everything else that has worked well for me over time and I am just sticking with it. Anything having to do with my sleep hygene has not been changed. The sole exception to no changes is that I finally got Apria to send me the hypoallergenic filters for my VPAP instead of their regular crap and I put one in the VPAP immediately.
In looking over my data since the start of zeros, I have noticed that my flow rate data looks generally smoother without as much variation as before, so apparently I am breathing more regularly than I was before.
I must reiterate. AHI=0 is not a goal that one should necessarily strive for nor is it one that i have. Sometimes it comes along and sometimes it doesn't. There are some people that see this AHI an a regular basis after getting their treatment optimized. I was not one of these however I was receiving very adequate treatment for at least 3 years.
I have gotten to the end of this missive and now wonder what my purpose was in writing it. I guess that it was to share some part of my experience and to let those who are not experiencing immediate improvement know that sometimes things just take time. After all, I have been on VPAP for 5 years
