test results

I can't seem to post - I get a message that my user name is already taken, but it is me???? I'm trying again. From what I have read, I am thinking that I should ask about the Remstar auto with c-flex and heated humidifier and a Resmed Activa mask or ultra mirage FF. How's that sound?? I had 154 episodes with my pulse ox at 53 once, but mostly is the 70 and 80s. It was worse on my back.. I also have tachycardia runs during the night. I am so anxious to get some strength. I seriously fell back to sleep after the first all night study and they found me in the lab at l:30 in the afternoon wondering what I was doing. I could sleep (or what I think is sleep) all the time.
