Well I am loving my new DreamWear Mask and I am more comfortable sleeping, but two of three nights I have used it have resulted in some of the highest AHI#'s since I started CPAP 16 days ago. My first night with the mask was actually the lowest AHI# I ever had, with a 1.9. Last night was a 7.5 with 18 CA's and 30 OA's. The night before I had a 5.2 with 19 CA's and 21 OA's. This is with no leaks reported and a range of 8-11.5.
The last couple of days I have noticed also that my Laryngopharyngeal Reflux has been acting up more than usual before bed. This makes me feel like I have a lump in my throat and I am constantly trying to clear my throat with a lot of swallowing. I am wondering if this could be why I am getting the higher numbers. My wife has also been sick and tossing and turning a lot, waking me up. Every time I wake up I have to get used to breathing with the mask on again. I am still getting used to CPAP I guess and seems like, while I don't have a problem sleeping with it, the falling asleep part takes more time than with out it. I also seem to cough more when first starting out, which could be from the LPR.
With no real software to see when my most problem times are happening, I have a DreamMachine, it is tough to know if it is a beginning of the night problem or something that happens all night long.
According to your profile your pressure range is 6-11. Yet you say you have a range of 8-11.5. Can you clarify?
I wouldn't be concerned. Your numbers look good enough for a beginner. It's normal for the AHI to take some time to settle down.
You might want to see a ENT about your throat symptoms, especially if they don't subside.
Have you called Respironics to ask about software? That company has a history of usually charging big bucks for it, but they also seemed to quietly make it available for free download at least one time. It's had names like EncoreViewer or EncoreBasic. It's pretty crappy software, but it's better than nothing.

I had more or less continual sinus infections for last 40+ years. Have not had since beginning PAP therapy 6 mos ago.
Have been sleeping in a reclining chair a month prior PAP therapy and even though fully reclined elevates my upper body slightly. Also reduces my strong tendency to sleep on my stomach.So two variables.
I have slept in a bed on occasion since PAP and not experienced the reflux so I believe the PAP therapy the major factor in this improvement.
With no software you might want to increase the minimum and see what happens.
Are you keeping a written log by your machine and immediately recording your impressions upon waking?
I use my PAP machine nightly and I feel great!
