Pressure changing continually

[bkkjames]

Every night there are large changes in the pressure between my min and max pressures (5-9) during the course of the night. I believe what happens is that the S9 ups the pressure in response to "Flow Limitation" events, and then reduces the pressure when these events go away. Here's an example from last night (which was a relatively a good night for me):



I am wondering whether I should try to adjust the pressure settings so that the pressure doesn't change as much. I was thinking of upping the min pressure to 6 or 7.

Do the changes bother you or wake you up? Because if they don't, ranging 4cm does not seem a big deal, especially at low pressures below 10.

I agree with Randy...If the changes don't bother you leave it alone. The machine is doing it's job...you have hardly any apneas or hypopnia's.
The machine will not react to the centrals (CA).
