Mouth breathing?

So are you saying that nearly all my apnea events are false positives since the vast majority of them seem to occur when my sleep stage is listed as awake?

I didn't look at all of them but the ones from 10:40 to 11 ish were all false positives IMHO.

Also, what made you conclude that I'm waking up first and then getting the false positives rather than the event causing the wake up?

When I see evidence of awake/arousal breathing PRECEDING the flagged event then I know the person wasn't asleep when the flagged event happened. Big gulps of air just prior to any event don't happen when we are asleep.
We don't take big gulps of air when we are asleep.

Do you know what big gulps of air look like?
Do you know what asleep breathing looks like?

I think so. The asleep breathing is my very uniform looking breathing going back and forth from -20 - 20. The big gulps would be a big spike up I believe? Is a big gulp happening at 10:45:36? So you think I woke up right then and took a big gulp of air rather than my body taking a big gulp of air and then waking up? As my watch didn't register me as awake until 10:45:49. So that 13 sec of abnormal breathing before the registered event at 10:46:26 is why I initially thought my breathing to be the cause of my waking up. But I believe you are saying I am waking up at 10:45:36, then my watch registers me as awake at 10:45:49 and then my machine flags the false positive at 10:46:26 and we're not entirely sure what prompted me to start to wake up and alter my breathing at 10:45:36. Is that a correct assessment of what you're thinking?

Thanks!!

Have you studied good sleep hygiene and are you trying to strictly follow it? CPAP treats breathing not sleeping.

Yep...when the gulp of air precedes the flagged event that means it was unlikely that you were asleep when the event got flagged.

So...IMHO....this snippet below shows asleep breathing to the left of the red line.
All that stuff to the right side of the red line is arousal breathing...you may or may not remember the arousal or awakening but you weren't sound asleep. The flagged false positive events are a symptom of the crappy sleep...but not the cause of the crappy sleep. Something else caused the arousal.
And don't ask me what caused it...my crystal ball is broken and there's nothing available on the data available that tells us what caused the arousal. You were sound asleep and all of the sudden you weren't sound asleep but we don't know why.
See that gulp of air right after the red line???? You don't do that if you are asleep.

I think you’re relying too much on the watch and on the time-synch between the watch and your machine’s output.
