Theoretical CPAP pressure while awake? - chris94546 - 11-08-2022
Just wondering, I have a Resmed Airsense 10 machine. If I am wearing a mask and utilizing the machine while sitting in a chair while awake, approximately what pressure should the machine typically assume. My machine still utilizes a moderate pressure while awake even when I keep the pressure range wide open. What gives.

Hi, chris I'm not sure, but one thing I notice in the first two or three breaths after I first connect the mask, before there's any pressure, is that it takes extra effort to breathe through the long tubing and machine with its filter, etc. So some pressure must be needed just to get compensate for the apparatus itself.

There is no CPAP that detects if you are actually sleeping. There is a auto ramp setting on some that detects the change in your breathing to stop the ramp. Otherwise there is no difference between sleep and awake.

Chris, my machine sometimes detects OA events in the first couple of minutes after I put the mask on, before I fall asleep. I've decided that it is because I breathe more slowly when awake but relaxed, than I do after falling asleep. OSCAR shows my respiration rate around 10 while awake, but around 20 while sleeping.
