I heartily agree. Auto PAP is the way to go. I fought for mine and it was worth it.
I was titrated at 11 CWP and originally prescribed a set CPAP at 11, but when I got my ResMed S9 Autoset home and tried the set 11 CWP for the first 4 nights I really struggled. Had terrible readings, huge leaks, and got up each morning feeling terrible. Then I broke down and got into the Clinical Menu of my machine and switched it to "Auto" and set a range of something like 6-12 and had my best night's sleep in recent memory! After a couple more nights and slight tweaks, I settled on an Auto range of 7-13 and am now getting AHIs well under 1. My best night ever was a couple of days ago when I got a .39!
The interesting thing is that, on average my pressure hovers around 7 (significantly lower than my prescription) most of the night, but has never exceeded 9 since I made the changes. And I sleep better than I have in years.
The thing is that I have yet to see the doctor for my first followup and the DME (equipment provider) hasn't interacted with me since I got the machine to see how I'm doing. So if I had kept the original settings prescribed, I'd still be struggling and feeling terrible when I get up each day.
Some of this may seem foreign to you right now, but it will be well worth your doing lots of research and going armed with good information when visiting your prescribing doctor. You may need to "stand up for your rights" to get the device you think is best for you, but it will be worth the effort in the long run.
Plan on being real pro-active in your own treatment if you want best results. Based on the odds, it's likely that your medical providers won't be taking a real active role in your ongoing titration ... unless you press the issue.
