exactly, I ditto Sleeprider!
I changed my upper to 13.5 because of that one night that I got to 15 and hated it. All the remaining nights were well under 13.5, so I could prevent badness without a nasty increase in AHI.

You'll note I am listed as an Advisory Member. I am honored to be listed as such. See the fine print - Advisory Members as a group provide advice and suggestions to Apnea Board administrators and staff concerning Apnea Board operation and administrative policies. Membership in the Advisory Member group should not be understood as in any way implying medical expertise or qualification for advising Sleep Apnea patients concerning their treatment.
That's sort of the wrong end of the stick as the Brits would say.
The rule of thumb that many use is:
One runs with ample top end pressure such that over a series of nights the MAX does not hit the top setting.
Then take the 95% pressure from that series; and set that at the max pressure.

yep. see your point, and my point is still valid. I got what I was looking for, and confirmed that ever since I have not gotten anywhere near that max, never once pegged out. oh, and I won't sample the aged seafood leftovers again, cuz that is what triggered the awful night.
YMMV and you don't gotta agree with me. I'm just as happy either way.
Helpful, that. My C.A's for the last four days have finally tipped the scale and exceed my O.A's. Last night by nearly 2 to 1 in the Central's favor.
Studies have shown that typically, CPAP induced central's fall away at about 8 weeks. Well the 26th of this month is my 8 week mark. We shall see. But either they are having a last ditch party in there, or the Doc is going to have to tinker with what works for me.
I am working at getting my lower pressure up. Good to know that really the issue is the lower being just right with auto, more than the top being just so.
I was thinking with a narrow range, one might have less wakings from run aways but it makes sense that the bottom number affects that all the more if it's too far from the sweet spot.
Other than Ramp time (5 mins and I'm seriously tempted to dump it, but as i'm in the phase of adjusting to increasing lower pressure, it seems prudent to keep it as an "escape" button so to speak, comfort wise.
The Manse Hen 4 horrible nights and counting.
Guess what I've discovered, Central's don't make for urinary changes in me like the Obstructives do. Interesting.

Susan, any chance you can post a detail chart from SH showing what's going on?
Limiting the high pressure is valid for exactly the kinds of issues you're raising here.
