OOPS!

I'm sorry people. I told you I haven't posted for awhile, and I AM getting older.

My AH1 is always in the lower numbers, not the 90% Pressure Reading. I guess I don't understand what the 90% figure represents.

Anyway, I'm cool. Still low AH1 and benefitting from CPAP, but don't know what causes different sounds on different nights.

By the way, since being here I've had major surgery and during which an AAA (Ascending Aortic Aneurysm) was found on my heart. Anybody know anything about how that might affect my CPAP use, or vice-versa?

here's an *excellent* explanation of what the 90% number means:

Thanks, PaleRider!

Should the 90% number be high or low?

It's a silly question, but I am not mathematical. I majored in English Literature. I can diagram a mean sentence, but all this data she talks about is Greek to me.

90% just refers to what pressure you were at or below for 90% of the night.
It may vary, but it is OK as long as your pressure can go a little higher if you need it.
As long as your AHI and leak rate are low, you are OK.
