Pattern of central vs obstructive hypopnea?
#1
Pattern of central vs obstructive hypopnea?
I know this must be in the wiki, but I've been looking and haven't found it. I'm sure I'm just having a brain misfire.

Somewhere I remember seeing discussion of hypopneas that are central in nature vs obstructive. They key point was that they could be distinguished by a pattern (a flat top or something) seen in the SleepyHead data.

Can anyone help me find this again? Thanks!

RE: Pattern of central vs obstructive hypopnea?
A central hypopnea is a normal breath, but one that is reduced in magnitude.

without the following

  1. An increase in PAP flow signal

  2. Snoring during the event

  3. Paradoxical breathing

Thanks! In my case, I'm having a lot of hypopneas. There is definitely no snoring, and I don't think there's an increase in the flow signal. As for paradoxical breathing, is there any way for me to figure out if this is going on? Or do you need someone else to be observing the patient to look at chest motion>?
