As far as I know there are at least two point of views regarding the use of CPAP for treatment of UARS. The first one is to titrate until there are no more respiratory related arousals (measured per EEG) (that's what Stanford seems to be doing) and the other one, Krakow's view is to aggressively round out inspiratory airflow cruves.
But besides theory, there are a few people on the internet who have seen success by increasing their pressure way above the one that was needed to treat their apneas.
I have have frequent arousals. At least that's what my recordings look like. My flow curves are not fully rounded.
I am surely grasping at straws here and welcome any input.
Can you show us some flow curves?
If you are still experiencing flow limitations, a bilevel might be a better machine. I had many flow limitations that I couldn't get ride of using my regular APAP machine. I raised the pressure up to 14 but my curves were still a mess and I was starting to mouth breath because of the pressure.
I switched to a bilevel, which I bought out of pocket, because I really wanted to see if I was going to feel better and didn't want to argue with doctors about it. I really wanted to know if my flow limitations were the reason I was still so tired so I took the gamble and was ready to loose the money.
Well, the gamble paid off. It turns out that with the pressure support set to 3 on the bilevel, most of my flow limitations are gone and I feel much better. I don't know why the bilevel works so much better to address flow limitations but it does.
