My actual pressure is 9 cmH2O. My AIH 2(two) weeks ago was 8.4 (decreasing). I changed sizes mask, Quattro FX, from G (Large) to M (Medium) few weeks ago.
But, in the last weeks (after reaching 8.4) my AIH changed again and reached 21.5 (last night) - The 21.5 AIH is the Media of 7 days, in LCD (not software).

I decided to ask my doctor, with Doctor Degree in Apnea and who diagnoticated my CPAP need, after night sleep.
My major complaint in pressure 9 was: during my sleep, I could not feel pressure from machine. I needed to breath strongly to catch the air and feel pressure (feedback).

Today, at the doctor, he was angry with me, as I changed the pressure from 5 to 9 (without asking him).

In my night sleep, mixed mode (half night without CPAP, half night with CPAP), my AIH was 36.7 without.
He told me that at my night sleep, the 5 cmH2O pressure turned my apneia to zero, even in REM sleep. Increasing my pressure from 5 to 9 (first 5 to7, then 7~8, the 8 to 8.5 and finally 9) was wrong. I needed just 5 (and period)!

Acording him, the machine could not be at complience with "me". Something like the machine was failure with wrong pressure.

He scheduled my visit to the next month (23/may) to show me that with 5 in pressure my apnea get "zero". So, I decided to accept his recomendation and test my original pressure, 5, with Medium Size Mask during 30 days.
He ended saying that he have 20 years experience, and 8 patients every night (night sleep): the pressure considered in my night-sleep is the recommended for my need. I cannot change pressure like i did,

So, whats your opinion ? Can I decrease apnea in 30 days, with 5 pressure ?

Any bet ?
...

Do you have access to other sleep doctor's? This one sounds like he believes in magic...Does he give you any reason why your AHI should improve over the next 30 days using the same pressure? Or just because he says so? Don't think I'd put up with this myself.

Hi,

This doctor says it has a large experience in apnea. In my area, I don´t see anyone with some "large experience", that I can trust.

The reason he said my AHI should improve, is because in my sleep night, the pressure used was 5 and I had no snore/apnea during my Sleep / REM state with CPAP.

Hi,

back again, few weeks later.

I´m discovering why, sometimes, at my sleep, i feel my CPAP machine (Respironics) like she "stops": I may have Central Sleep apnea disorder.

Thats the reason my CPAP pressure, since 5 to 9, didnt make any change in treatment (still remains about 25 to 21 AHI).

Yesterday, i had another Night Sleep at Clinic, to investigate my apnea. But everything indicates is Central Area Apnea.

So, even at 11, 14, 15 pressure, my AHI could be high and would be no positive treatment for my case.
