See what I mean? Fuzzy thinking on my part. I CAN'T HELP IT! I'M SLEEP DEPRIVED!

Thanks.

I currently have a stash of Nasal Aire II cannulas in Small or Extra Small. Please PM me if you would like them. I'm interested in bartering for something strange and wonderful that I don't currently own. Or a Large size NAII cannula. :)

What range is your autopap set for? Sounds like it is the minimum pressure that needs to be raised. Which is often the case for most people, if the minimum in the range has been set very low, like at 4 or 5.

If you were using CPAP instead of autopap, what was the single pressure suggested by your sleep study? In other words, if the doctor had prescribed "CPAP", what single pressure would he have put on the Rx?

I think they both (min and max) need to go up. The min was 10 and the max was 15 last setting. The pressure chart still flat lines against the top range for 30 to 40% of the time (90%P=max), so I know max needs to go up. And since lots of OA events at low pressure, that too.
Sleep study showed severe OA but I need to go back for the titration; long story and long wait for next study. In mean time I am self titrating with APAP, gradually, moving min and max up a bit each day and studying the encore viewer charts carefully each day; they seem clear. Started a few days ago at 7 and 12.
