Essentially, it is the number of "events" per hour.

Anything 5 or less is considered "normal", so at 1.2 you are doing great! If you up the pressure a little bit on the cpap you may be able to get it under 1. My DME left the instruction card for changing the settings on the machine with me when he dropped it off. I'm not sure he was supposed to, but I used it to adjust mine up .5 and saw the AHI drop. I'm not sure that is making any significant difference, but I figure it can't hurt. My doc was impressed when I told him last year.

So your machine gives you that number? I would be most interested in that if I could find it- kinda proof positive that a difference is being made, even if I don't really feel it.

Yes, a lot of machines have a digital readout that gives you usage statistics and your AHI. I know some don't - my father's, for example. But I think even his has a card that reads the data so that his doctor can review it. Yours should as well. If there isn't any way to track your stats, you should talk to your doctor about getting one. As you say, you don't have any way of knowing if its working otherwise. I'd press hard on that if I were you.

I will, thanks! And, machines are quite quiet.

As others have said, its pretty quite. My wife describes it as white noise.
