Quick AHI question
#1
I've been reading the various posts about trying a large size pillow for the Air Fit P10 mask. Last night is the 2nd time I've tried one and I seem to have good numbers (for me) with that pillow. I should know the answer to my question, but I don't - so please have patience.

The leak number was only 2L/min
AHI - 1.1
Total AHI - 0.8

How come the difference in the two numbers. There was 0 central so I'm really confused how the machine comes up with the numbers it did.

AHI = Apnea Index (AI) + Hypopnea Index (HI) = 1.1

AI = obstructive + central + unknown = 0.8

The difference in the two numbers is Hypopnea Index (HI), AHI - AI = 1.1 - 0.8 = 0.3 ... HI = 0.3

Hi GrammaBear,

Zonk's answer (which is same as mine would have been) assumes you meant:
AHI - 1.1
Total AI - 0.8

Take care,

Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment. The Advisory Member group provides advice and suggestions to Apnea Board administrators and staff on matters concerning Apnea Board operation and administrative policies - not on matters concerning treatment for Sleep Apnea. I think it is now too late to change the name of the group but I think Voting Member group would perhaps have been a more descriptive name for the group.

You are doing great, don't worry about numbers to much, as long as you don't feel tired. A lot of people would give their right arm for an AHI as low as that Smile
