AHI index and oxygen saturation

I was just reading about AHI and it said apnea must be 10 seconds with decrease in oxygen. My home study showed oxygen 100%. So no decrease. It also showed 162 hypopopneas and 37 Apneas. I'm classified moderate with 22 per hour. If I had no decrease in blood oxygen how is my test accurate. Is this possible.

Sounds like your home study program is flawed. Time to go to a real sleep study, or wait until you climb out of De-Nile then go. Jim

There doesn't need to be a desat for an apnea to happen or for you to 'have' apnea. I think they may not have worded things well, maybe meant either/or, but you don't have to desat to have apnea.

I think it is very unusual for anyone to have 100% saturation on a pulse ox device for any extended period, especially while asleep.
I would question the accuracy of the pulse ox and I absolutely would want a complete detailed copy of the sleep report including all the graphs. The suggestion of 100% saturation throughout the test would make me question the entire experience.

Ty. I will ask for the full documentation. I got one sheet with description of apnea. I an wondering if it was flawed too. Also I have gel coating on nails and they said that didn't matter.
