Last 3 days I've noticed the pressure starts to oscillate when I'm laying down by side. The mask starts to move up and down and this pressure makes me breathe faster and faster as it is like it is entering in resonance, so I can't sleep. When I have my face upward it doesn't happen or it is too small. Pressure is 12 and it happens using the ramp or without ramp, also I have modified the humidity and it doesn't change. Help!!

My suggestion would be to download SleepyHead and track your readings on your PC or Mac. It will show what the pressures actually are.

SleepyHead is a free software program that you can run on a PC or Mac. You require a SD card reader to get the data from your CPAP to the computer. SleepyHead works but is not being developed any longer. OSCAR is a replacement. See a thread on it down the page a bit.

Can you do an F12 of the Daily report that shows mask pressure as one of the graphs? Note where it gets saved, and then drag the image file into a message here. It might show something.

Edit: To explain a little more, the Pressure graph shows the set pressure (it should not change), not the actual Mask Pressure. Also what is the make and model of your mask? Could flow be restricted somehow?

It's says it doesn't record useful data to graph in Daily View. The mask I'm using is P&F Simplus M size but according to the template it brings I should be using L size.

BRICK! :(

About all I can think of is that EPR is on, which causes pressure to cycle down during exhale and up on inhale. However, I see that you are reporting that EPR is off.

If you push the round button when the machine is running it should display current pressure. One check would be to see if it is cycling up and down.

Can you explain the oscillating a little more please? I have something going on with my S10 that never happened with my S8 or S9 If you've ever left your mask on and just shut the machine off, it just sucked on to your face.

that happens after a few hours of use it feels like the sucks onto my face and replaces in almost a pulsating rhythm.

That is the feeling, pulsating rhythm of pressure (inhale and exhale) getting faster with the time and make me breathe (inhale and exhale) at the same rhythm. It happens when I lay down by side.
