Resmed 11 turning off

I have noticed for at least 2 days when I wake up and look at my usage hours it is much less than I wear it for about 3 days I wake up struggling to breathe last night I woke up gasping for air sweating and blood pressure was 179 over 95 really scary wore it from about 830 to 1130 only said 1.5 hours usage.almost went to hospital.need help said mask had poor seal but that has happened before and nothing like this will not wear again till i have it checked out

Is your power bad? This will cause the machine to turn off. Was the machine off when you woke in panic? That is what you should do! You should never wear the mask when the machine is not running. I run my machine through a computer UPS so it never quits.

Are You using the auto off feature ?? There is a problem with large leaks and the auto off shutting the AS 11 off ..
Auto off and on are separate in the machine controls .. Good luck getting this fixed !!
