took the liberty of breaking this out on its own from another thread so it doesn't get buried:

"Hi, this is Sherry from the 'Is This Machine Obsolete?' thread..Due to all the confusion in my getting my machine last week, I did not set it up till yesterday. This was due to a lot of encouragement from White Beard, thank you very much!
Some asked that I keep you posted on my experience with the Adapt SV, so this may be way too much info, or not what you want. Just don't respond if it is irrevelant. It is just that it is 2 am, it is my first night trying the Adapt, and I am waiting to get sleepy so I can go back to bed without it. Probably typical for first night.
Last night I hooked it up, did the mask setup as per the User Guide, the mask I have is only nasal pillows, which is definitely a nono on the ResMed site..but the clinic person insisted they would work fine, so..I used the full face setting as White Beard suggested, then realized that I did not have the little tube connected, so fixed that and started again, and got the invalid reading..over and over and over..I figured it was due to the mask type. Decided to hunt for some of the other features that I have seen discussed here, and found to my dismay there was no Results menu, only Service and Setup. Not happy. Bundled it all back up in the spiffy little case, intending to return it this morning and go from there..

This morning I thought, I will check out the CD that was in the case to see if I can find anything else out, it turned out to be the clinician's guide. ( I had tried to sneak the hard copy when I got the machine, but the person noticed it was gone and I had to give it back < :-( )
Anyway, it said in the PDF (which I have saved on my hard drive) that to enter the Clinician's setup guide, to hold down the arrow button and button to the right of it for 3 seconds and it would take you there. Tonight I did just that. (I have to mention here that the crt called me today to see how I was doing, and I informed her about the results screens etc. not being visible. She said, oh gosh, I must not have enabled that. I said, that is OK, I know how to do it. She said, gee, you are learning so much about this machine I will be calling you for help. She also told me I could use the mask, just SKIP the learning setup)
I enabled the Results, the mask fit, the leak rate, and everything else in there. Also deleted the data as it was all from when I was trying to get the mask setup the night before. Then I hooked the mask back up, skipped the learning setup as she suggested, and it worked fine. Except it was blowing so hard it was making my ears pop and also making my nostrils puff out. I went back in and lowered the min (it was set for 6-13) to 4.8, which was much better but still pretty pushy, especially the rate of inhale exhale, but I was hesitant to make it lower. (Note--I suggest you write down the original settings, I should have thought to do it before I changed anything.)
When I went to bed, I tried it for about 5 minutes, air was gushing thru the exhale vents in the mask, finally I got up and changed it to 3.5. Much better, although it was breathing a lot faster than I was. After a while, I noticed that about every 2 minutes, the inhale/exhale speed was slowing down. Don't believe this machine has a Ramp up? Not in the menus. Anyway, it was nice to see that it was actually responding to my breathing pace. I felt a little optimistic for the first time!
Then another problem--I started drifting to sleep, but every time I would drift, the machine would gush and wake me up. Of course, I guess this is exactly the problem, I must stop breathing or hold my breath when I start dreaming. ( I hold my breath a lot even when not sleeping, when I concentrate on something). However, I'm not sure if I'm holding my breath, or just breathing more slowly all of a sudden. But I agree with Rich M's doctor, there is a definite feeling of not being able to breathe on your own. I did relax at one point and just let the machine breathe for me, which made it very happy, when you try to fight it, it retaliates with a noseful of air.
Will try again tomorrow night, I think I can get used to it if some of the abruptness can be smoothed out. I do not remember experiencing the sudden pressure changes when I had the good sleep test t the lab (first one was not good), I went to sleep OK and only woke up because the mask had pinched my nose till it hurt, not because of blowing air.

As I said, this may not be of interest, but I'm getting sleepy and can go back to bed now! LOL"
