Wow. Wish I had such results! And I've been at it for 2 months, so can't offer help here.....
I am completely baffled as to how you can have AHI of 2.1 and 2.2, and then on the last page show an Average AHI of 3.0???

I see a beautifully low leak rate, a nice low AHI, and a person who is lucky that such a comfy low pressure is all it takes to keep their airway open.
In short, BEAUTIFUL, just as myth said.

I think I can interpret that. It is averaging all data. The rest of the data is for just 2 days.

Cool. I was afraid I was missing something since I don't know how to interpret all the little details.

Can I say respironics math sucks? Have I ever said that before?

Hey take off your socks, the count might change
I'd think you would have to add up the total time slept for those 2 days and divide by number of events seen divided by 60 to come up with that average.
someday science will catch up to what I'm saying...

I am glad someone understands respironics math - I sure don't.

Easy. 2.1 rounded UP is 3. 2.2 rounded up is 3. 3x2/2=3. Or maybe it's 2.1+2.2=4.3/2=2.15 rounded up to 3.
It's new math I tell ya.

Yep.....it's Respironics' "new math"......and it's just as as simple as the example you gave.
Any fractional number above a whole number gets rounded up to the next whole number. Even if you had a 0.1 and 0.2 AHI on two consecutive nights, it would still round them up to a 1.0 AHI on the summary reports.
