Thanks again, jnk! That makes sense to me. If the waveforms of hypopneas and flow limitations are different, then the equipment must be able to differentiate them. It probably has something to do with how the machine reads the pressure.

That is a continual source of amazement to me.

He's probably the father of modern sleep medicine. I mean, look behind the glasses. You can see the wisdom in his eyes!

But seriously, -SWS's posts have been very informative. I enjoy reading them (and trying to decipher them too!)

Is there any literature on this?

One of the odder things that xPAP therapy has brought out for me is that in the process of falling asleep I can actually often induce it by slowing down the respiratory cycle substantially - to where if I pointedly don't inhale for a bit it can often finally get me knocked out. Otherwise, don't have centrals. Been meaning to ask my own sleep doc about this, but always good to do a review first.
