Interpreting non apneic flow rate events
I've read through the sleepyhead guides on interpreting flow rate but I've had a few situations come up pretty frequently that I don't fully understand and I am unsure what settings I could change to correct them.
Situation 1: Expiratory flow oscillations
This might just be expiratory snoring but the diagram looks different than what is in the sleepyhead guides
[attachment=9721]
Situation 2: Series of small "events", these do not last long enough to be classified as events but there are a bunch of them in a row, is this something I should watch out for?
[attachment=9720]
Situation 3: Twin peaks pattern. A large breath in, followed by a pause followed by another large breath. I see this pattern a lot, any idea what it means? This doesn't quite last long enough to classify as an event but it is really close
[attachment=9719]
Situation 4: I recently turned off easybreath to avoid CA detection, as a result my normal flow morphology changed from a rounded peak to a sharp downward drop. My guess is this occurs because the machine does not ease transitions from EPAP to IPAP and vise versa. Are both waveforms OK? Is one considered better than another?

Thanks in advance for your help. I've been really impressed by the kind of feedback I've seen on the forums so far.
