Theresa, I am sure I do better with the self adjusting Cpap than with my old one. I had been on a setting of 11/8 for about 10 years. With the self adjusting, I have formed a habit of looking at the pressure just after I awaken, and before shutting down the machine. The pressure usually is in the 14-15 range (in this system, the exhale is a preset reduction, I think 4 below the inhale); but it occasionally jumps to 16, and even as high as 18. So, the machine is working to provide what I need.
I typically rouse up about 45min to an hour after falling asleep. Sometimes this happens over several hours sometimes not. Just like before I was diagnosed. My fitbit says I have 18-20 arousals a night. Have no idea how accurate or significant that is.
Anyway, just venting because no one has ever answered why the original sleep Tech recommended, and the Dr approved, a BIPAP; and why no one else seems to listen when I explain that the BIPAP worked beautifully, and the CPAP never so well.
The other point is that I have had two (or is it three?) follow-up studies over the 16 years. In every case they waste half the night re-diagnosing that I do have Apnea. After that, they wake me and slap a mask on; starting at a very low pressure. Finally, once the apnea is controlled (at least temporarily), they make judgements based on very little sleep time.
Of course there may be other factors in my restlessness that have nothing to do with Apnea. I am fast approaching my 80th birthday; I have aches and pains and have always had leg movement issues which are controlled with mirapex.
Well, enough. Glad to find this forum and I will check it for information. (On one forum I found the answer to my mouth breathing--tape your lips shut. It works.)
