Susan,
Please start a new thread, your own thread.
While asleep the body hours into a state that requires less urination at night. There lies the problem, asleep. As one with sleep apnea we don't get enough continuous sleep. Our CPAP therapy gets us there but the body needs to relearn this behavior and it takes a while.
ResMed has a brief tutorial on how to help with your therapy about managing your pressure issues. Here it is, quoted in its entirety. "See your doctor"
To best help you we need to see your data, specifically the daily charts from
OSCAR. This lets us see on a breath by breath basis when necessary so please download
OSCAR and post the daily charts, see my signature for how, the organization link for what to include. Thanks.
Since your complaints are mostly about pressure is like you to do an experiment.
Get a tall glass of water, and a straw.
Now place the straw all the way in, now blow bubbles. Childish, I know. Any troubles or issues?
Didn't think so. A tall glass typically will hold about 8 inches of water, that is 20 cm of water or the maximum pressure your CPAP is capable of. Try the straw 4 inches deep and same thing. That is the max pressure your machine is set at.
Point is your issue is not likely to be pressure, but rather flow. To counter flow either exhale or turn off the machine if you don't like the sensation of the blowing. The matching is blowing as hard as it can because it is not meeting it's pressure setpoint.
