Been trying the ASV for a while, again, getting more fatigued...as per the last few years, so....
I have been experimenting with a couple of breath/heart techniques, I have always believed I have odd breathing rhythms, but could never get any doctors interested in that path, so was interested in anything that might improve my situation.
After a couple of months of practice with these techniques I decided to bite the bullet and try my machine on straight CPAP, as that is what I have been titrated on, twice, with no sign of central apneas. I started on a low pressure, 6.5cm, and over a couple of weeks have increased the pressure to the titration pressure, 11cm.
The odd thing is that at no time while doing this have I had any daytime fatigue and I sleep really soundly.
Anyway, my AHI as of last night was 4.32, which is close to a miracle on straight CPAP for me. I feel great, better than at any time on CPAP/ASV. I am going to slowly increase the pressure to the sleep doctors recommended 12 to 13 cm and see what happens.
It has been a strange, long and winding road...but I am so glad I followed my intuition and researched breathing and heart rate variance issues.
Take care, and thanks for all the support over the years...
