What are they seeing that tells them that? I'm assuming it's something in the Flow Rate waveform data, but I'm not sure.

Thanks!

By the way, I've discovered my BEST consistent sleep so far is by setting my machine to Fixed cpap mode, 7 CmH20 start, Ramp = 30, pressure set to 11 CmH20, EPR = 3. 

Using those settings, my Flow Rate waveform is consistently much improved/not as crazy as over autoset mode, but apparently time has also allowed me to now tolerate a much higher pressure, as long as it's fixed. I think there's a bit more tweaking to do as I believe I have a few too many micro arousal's in the latter part of the night, but that may be due to spinal pain that builds up towards the end of the night, and/or bronchitis coughs so may not be fixable via cpap. I'm not sure about exact causes yet, but back pain for sure can be quite bad around 4-5am depending. But things are looking MUCH better now sleep wise!

By the way the last chart showing an OA isn't really an OA. Not sure why it read that way. You took a deep breath and that sometimes triggers a false report of an event. But usually it will report a CA falsely not an OA.

All this probably means is you may be occasionally exhaling through the mouth but maintaining a good seal on the mask otherwise.  Results are very good, and there is not much there that would require any correction.
