Mouth Leaker?
#11
(05-28-2015, 05:34 AM)quiescence at last Wrote: DV - from the plot, which you probably posted because it was the interesting part, there is no correlation between leaks and expected attenuation in flow rate. while the pressure setting is 9-20, his apnea is well controlled and constant at 9 (plus the standard PRS1 pressure spikes to 10.5). The plot shows no adjustments to pressure throughout this clip. it is interesting that the snores happened when leak was low. you might expect the flow rate to be attenuated at those points - which does not seem to be true, and you might expect that he is mouth breathing when he snores which would increase the leakage (theoretically). if he could somehow not leak when mouth breathing, it would probably show an increase in TV and flow rate. so, based on this, I would be willing to believe he is not mouth breathing. This leaves leaking at mask to face interface. Would he be willing to try pad/liner for a trial?

QAL


btw. Did his resp get bumpy between 23:35 and 00:25? If so, he may have been REM sleeping and pretty un-disturbed by the skin interface leakage which would normally awaken him.

Why would you expect the flow rate to attenuate due to leaks?

The air is not coming back out the nose, so flow would show as less. Maybe I actually meant that the exhale would be attenuated.

Perhaps the inhale flow would actually be expected to increase.

Nope! Every once in a while I'll wake up with a line on one cheek because of the way I'd been sleeping.

Nothing compared to the marks I had from my nasal pillows mask strap and the chin strap.

If he's not compliant the data doesn't mean anything. Use an oximeter to convince him that his life is at stake.
