Help! started great, now poor

During sleep your inhale is a brain/body triggered event, but exhale is not a forced event.  Hard to believe, but once the forced inhale has occurred, the 'balloon' that just got blown up now simply deflates 'on its own'.

Since you are not remembering (or feeling) a forceful exhale, it seems as if you are not exhaling (or not exhaling enough).

Humm.  I wonder if this is my issue:

The balloon i speak of is your lungs, but it gets no where near ready to pop, just slightly more inflated.
When pressure relief is used (EPR on some machines, BIPAP or APAP, or IPAP-EPAP on others) the exhale pressure is brought lower than inhale pressure. This sort of super- boosts the balloon so there just a bit more 'deflates on its own' action (when asleep).
While you are awake, this can feel like you can't exhale, because the deflation already had mostly occurred ha ha without your active compressing.
Worry sets in which can lead to insomnia or tossing the scary machine alien.
The data from our daily flow graphs can show we are getting good exhales, and give us peace of mind.

Good to know quiescence at last.... I just do not like waking up in the middle of the night feeling like I can't breathe out. I am trying out new settings. But we lost power the last few nights so no good data as of yet.....
