Thanks, I will do both. I have to say, from day one of using the machine, I feel like a million bucks; I had no idea how crappy I felt before!

My machine doesn't have any graphics like this, or at least I haven't been able to find it.

I just started on my dreamstation about two weeks ago. All of my numbers look pretty good except for periodic breathing. It averages between 7 and 11%. Last night I slept great, 100% mask fit, 7 hrs of sleep, low AHI, but periodic breathing was 17%! Should I be worried? A recent ekg showed no signs ...
