Looking at just the one night is not extremely satisfying, as you might be surprised how much the treatment (and need for it) varies from night to night.
However, my observations from http://www.apneaboard.com/forums/attachm...p?aid=1676
Your pressure really does not ever return to below 10 for any of the treatment time. (eliminating the very first ramp and the immediate increase at about 12:15 (00:15).)
From that observation, I would guess that any increase in minimum pressure that is still below 10 is not going to decrease any of the results. I would still take small incremental steps to reach a start pressure of about 11. What is usually suggested is that the minimum pressure be adjusted by no more than 1 cmH2O about every 4 days.
What we usually find out is our own sweet spot ends up being above the original median pressure (yours being 10.92 cm) and no more than 2 cm below our original 95% pressure (yours being 12.7 cm). This suggests I would set my pressure above the greater value (10.92 or 12.7-2.0=10.7) - suggesting a pressure of about 11 cm.
For the near term (if it remains comfortable) suggest ramp start at 8, ramp time 5 minutes, start pressure 10. Keep 4 nights, then adjust ramp to 9, and start pressure to 11.
My note about comfort is really about how the pressure feels to you while you are falling asleep. Once you adjust to being just fine with the effective treatment (11cm) as a start pressure, eliminating the ramp is a great idea. Many suggest dumping the ramp right away.
ps. other general observations are: (1) that hypopneas seem to be happening at higher pressures, but still seem to correlate with the higher flow limitations. (2) CA events seem rare and are not in the periods of higher pressure and not combined with regions of hypopnea as seen in some patients. (3) Leaks seem to be confined to small episodes. None of (1) thru (3) suggest changes should be made in your treatment or habits, and (2) is actually a good sign.
pps. EPR is fine to add if you want to try it. Some have found that they can eliminate some H by trading it for CA (generally with increased pressure), but also found that it decreased their satisfaction with sleep quality. Some have found that they can trade some H for some OA (generally by decreasing pressure). I initially feel neither apply to your case, since I think your H are happening as a natural consequence of a healthy central nervous system feedback to make up for (slight) flow limitations.
