Problem with my Airsense 11

[eddieb76]

I've had an Airsense 11 for about 3-4 years now, so probably getting ready to be replaced, but I have a new problem. I want to specify ahead of my issue that I changed nothing about the CPAP, and this problem started just five days ago. I never had this problem before, so it is not normal. About an hour into my sleep, the CPAP pressure suddenly jumps extremely high and wakes me up. I'm breathing normally, but it stays high. I take the mask off, and it stays high. I turn it off and back on, and it's still high. I go to sleep without my treatment. When I wake up the next morning (suffering from lack of treatment) it is fine. Next night, same thing. I'm pretty sure it's malfunctioning, but I'm currently in between changing my healthcare from Tricare to the VA, so I currently don't have any way to replace it. I was hoping maybe someone here might have had the same problem and figured out how to fix it. If not, I still have my old Airsense 10, so I'm probably just going to start using that again, but any insight is appreciated.

Software Reset it. Turn the machine off wait a few minutes, turn it back on.

Post some OOSCAR charts. This might give us some clues to the cause, and maybe a work-around. Leak, set a maximum upper-bound,...

I have the same issue with the Airsense 11. Found that it was the water reservoir that wasn't sealing properly. After sliding it out and back in, it would usually seal correctly. I didn't have the issue at all with the original reservoir -- but the 6-month replacement always seemed slightly off. When this occurs, I'll usually get the burst of air as soon as I turn on the cpap. I'm almost due for the next reservoir replacement, so hopefully that will correct it.
