Woke up gasping for air?

Hi all,

Firstly, I'm new to this board so please bear with me. I also have UARS now OSA. Last night I woke up in the middle of the night gasping for air with similar symptoms I get when not using my APAP device (dizzy, heartbeat elevated etc. -also no nothing is wrong with my heart, I've had a full workup from a cardiologist very recently).

My question is, based on my linked sleepyhead graphs, is this due to my APAP device not performing well enough to keep me asleep/provide enough pressure during this "Flow Limitation" event or something else?

I have a Philips Dreamstation APAP machine. Thanks appreciate any feedback!

From the look of the events graph though...I suspect that you needed more pressure for some reason and the machine couldn't deliver it fast enough and some apnea events slipped past the defenses and were very likely responsible for your symptoms.
