Occasionally, I wake up with 15+ (even 19+) pressure and that pressure appears to blow my mask off my face. Even after I wake up and check the machine, the pressure stays at the same high level until I turn off the machine. It is set at 5-20. The high pressure is stuck, wakes me up and may be messing with my heart rate. I will get OSCAR eventually but I want to know if this is common or the norm??? Thx in advance. I am new and have been using a CPAP now for a couple of months.
You really need OSCAR to see what is causing the pressure to ramp up. Normally the machine would be detecting obstructive events, flow limitations and snoring and that causes pressure to go up. With OSCAR you can see what events are occurring.
However, you can limit the maximum pressure by going into the Clinical Menu, and changing it to something less than 20 cm. See the link below for how to do this. But, if you limit maximum pressure and the pressure has to go higher to limit events, then your event frequency (AHI) will go up.

I have an OSCAR report from last night I was hoping Sierra and others can comment on. About 3 hours into my sleep, the high pressure appeared to have started, which woke me up, but the only way I could get the pressure down, even after fully awake, was to stop the machine. I will try to figure out know how to post my OSCAR info. Thx in advance!
From what I can see your machine is behaving normally. Obstructive apnea events and flow limitations seems to be triggering the increases in pressure. Your obstructive events seem to be occurring at certain times of the night, and not at other times. I would wonder if the sleeping position may be the difference. Most people are more likely to have apnea events when they sleep on their back. Also your events seem to be coming in bunches. Some people have some success with wearing a soft cervical collar which can help prevent kinking of the neck. You can find them at Walmart or on Amazon. May be worth a try to see if it helps.
On displaying the sleep report I just make the daily report full screen and press F12. That will let you save it as an image. Then left click on the file and drag it into an open post here.
Three hours into the night is the point at which the first major cycle of REM sleep occurs. Typically, people have many more apneas during REM. My overall AHI was only 19, but my AHI during REM (when I could sustain REM) was 83, and Imwoild desaturate to life threatening levels.
The reason is that during REM, to avoid you acting out your dreams, which can be dangerous, your muscles disconnect from your brain. Sleep walking, sleep eating etc., are what happens when that disconnection is incomplete or unsuccessful. I suspect your flow limitation are occurring during periods of REM sleep. How badly are yoj desaturating? If you don’t know, check your sleep reports or use overnight recording oximetry.
