Last nightI lowered my max pressure from 16 to 14. My max pressure has never risen above 10 or 11.
The question is: Does the degree of change in pressure depend on the available max limit.
My pressure would not raise above 10 or 11 with the 90 % being in the 9 range. Last night my pressure MAX was 8.88 with a 90% pressure of 8.16.
AHI of 1.1, zero OAs, and split between CAs and HAs.
I am not sure if I am explaining this right but does the pressure change algorithm look the available change allowed.
I am thinking that my pressure change was not as severe as before which is allowed me to sleep better.
I don't think changing the maximum setting will cause the machine to operate in a lower pressure band generally. It will go as high as it needs to and you can sometimes see the pressure graph bumping along the maximum. This indicates that it wants to go higher.
On the other hand, there has been some discussion that Resmed machines respond aggressively and can overshoot or "run away" when raising pressure in response to events.
As always with apnea, one night does not constitute a trend. It would be interesting to look at a week's worth of SleepyHead graphs before and after the change to see what's happening over a longer period, and in a bit more detail.

If that were the case, there would be no reason to lower the max pressure. Unless the purpose would be solely to stop runaway pressure increases.
