RE: Understanding the AHI index - SuperSleeper - 02-27-2012

There are no conclusive answers for what constitutes mild, moderate or severe Sleep Apnea. There seems to be a degree of consensus on the ranges; however, opinions do vary amongst professionals.

Generally speaking, here's the consensus opinion:

AHI < 5/h = No Sleep Apnea

AHI 5 to < 15/h = Mild Sleep Apnea
- (some say that 5-10 would be called "borderline OSA")

AHI 15 to < 30/h = Moderate Sleep Apnea

AHI > or = 30/h = Severe Sleep Apnea


So, under these guidelines, your OSA would be moderate Sleep Apnea (albeit on the higher side).

But don't read too much into the numbers. Your numbers can and will change as your body, age and medical conditions change, and there is quite a bit of variance between various sleep centers, their equipment and ability to accurately determine these numbers. More important is that you get treated and that you feel better.
