In meantime I did all sorts of adjustments and finally, I feel better/optimum(great, not yet) between a 8-13 pressure. My AHI improvement is below 3 from 64 events per hour withwout cpap(severe apnea sleep study showed a year ago). I developed sleep apnoea after a bad episode of hypothyroidism last year.
A little advice would be welcome, everything it's ok except one thing. For a few days I developed an ear problem(I feel my ears clogged and I disoriented/dizzynes when I wake up in the next morning), and that buzzing me all day long. Also my tinnitus has worsened. I believe this is happening because of exhalation-pressure(i use the Afelx-3 but it seems not help) is too high for me. I know the 8-13 is not too high pressure for the most of us but maybe I'm more sensitive.I do not have sinus problems.
I've thought, maybe if I use/switch to an auto-BIPAP, these inconveniences will disappear.?
What do you think.
