This is nothing more than a curiosity, really. The machine has a flow meter and uses the readings from that meter to figure out when you're breathing out, in, out, in ...
You establish a pattern that it recognizes and then when you deviate from that pattern it may score it as an event. Officially you have to stop breathing for at least 10 seconds to score an apnea. It's no big deal and happens to everyone all the time.
When it happens too often and too much you get diagnosed with the ailment called sleep apnea.
Quote:I still wake up two or three times a night and begin deep breathing while entering into what feels like a sort of panic attack. I never seem to see those arousals associated with any kind of OA. I have a few seconds of really crazy breathing then I wake up usually panicky and uncomfortable for 15 or so minutes. I'm just trying to track down clues while losing weight and changing my diet. More than anything I'm just glad to see the OAs virtually gone now that I'm using consistent therapy. Thanks so much for the input.
You can look for Flow Limitation, which is a lessening of the breathing, not severe enough to be scored as an apnea or even a hypopnea. Your body may be interpreting this as a warning that an apnea is about to happen so it freaks out, shoots you with some adrenaline, and wakes you up.
Your body has had to do this many many times per night, every night. For years or even decades.
Once it figures out that it doesn't need to do this any more it'll stop.
It just takes time.
If it doesn't stop, or if you're concerned, discuss it with your doctor. All I can tell you for sure is that this same thing happens to lots of us.
