I think I know what you're saying. However, thats not what I'm using. This is a mask that covers only the nose. The hose connection is directly at the nose. I don't want you to get rid of your mask due to this subject because you seem to be talking about a different one.

I will look for that. Thank you!

Its a nose-only covering mask. It isn't an electrical issue because I can reach over and hit the button and it will start back up. Also when I roll over, the machine doesn't move, only the hose and I have it secured. I really can't, for the life of me, figure out what changes when I roll over but it happens 100% of the time. Must be something to do with the air ventilation but it has me baffled. It doesn't happen right away. It will usually run for another minute or two before it happens.

I have the Resmed Airsense 10. I'm mostly happy with it. However, sometimes I get restless laying on my back all night long. Sometimes, while asleep, I roll over onto my side. My machine will shut off afterwards. This happens every time I roll on my side. I've tested it and there is no more loss of air from the mask than while on my back. I can roll on my side and adjust the mask to perfect coverage and it will still shut off after a few minutes. I cannot figure out how the machine knows that I've rolled onto my side or why it shuts off due to it.
