RE: APAP to CPAP
Oh, that's a good point, Sleepster. See, I knew we kept you around for a reason!
And yes, sleep apnea is an important thing to tell the doc prior to any surgery. Some surgeries, they use a tube down the throat so xPAP during the surgery itself would not be needed. But it certainly should be in the recovery room! I've been sent home early twice because my snoring kept the other patients away. And neither time did anyone say anything about sleep apnea.
MJ, I will someday replace my oximeter for the wrist type as well.

Not tough to do since my week is at 15.00 and my month is at 14.59 and my CPAP is so old it only has whole numbers, so I would just set it to 15.
I take it the old CPAP is not data-capable?
Like zonk said, 5% of the time you are above 15 cm of pressure, but what's going on the other 95% of the time!?
Try setting your APAP in CPAP mode at a pressure of your choosing and see how the AHI looks. Basically, you'd be using the APAP to make an educated guess at what the CPAP pressure should be. Other than that, I don't see any way to figure it out.
Thanks Sleepster. I know. I have been putting that off. You know I really hate to mess with anything that is working! And I REALLY hate to go back to an old CPAP, but you are right. The only way to know for sure is to set it up and experiment. Maybe I could just buy another APAP?! LOL!
As always, YMMV! You do not have to agree or disagree, I am not a professional so my mental meanderings are simply recollections of things from my own life.

RE: APAP to CPAP
Be careful if you set CPAP at the 95th percentile value. Understand that if you do that, there is a danger that you could have more central apneas. Since most of the time your pressurs are the 13 or 14 range, I probably woudn't go beyond 14 for starters. If your AHI isn't acceptable and you need to use a higher number like your 95th percentile value, after a night on that, look at your SleepyHead data to be sure you aren't encountering a lot of centrals. The only problem you may have is that your CPAP machine isn't data capable. In that case, you may want to try all of this out on your APAP machine. before it fails. Put it in CPAP mode to see what these fixed pressures do to your AHI.
I forgot to mention, that in addition to a 15 pressure possibly causing centrals, you may find that a pressure that high is too uncomfortable for you, since you are accustomed to lower starting pressures with your APAP. Of course you could try ramping it up, if your old CPAP machine has that capability, as you probably don't use that feature with your APAP machine.
