Here's a video of my CPAP while measuring the DC current. Sorry I had to keep the video extremely short to keep it below the file size restriction but fortunately it is more than long enough for this demostration

I have the CPAP pressure set to 15cmH2O. The machine requires about 1.5 amps. The video also shows the current dropping to about .5 amps while I breathe out - this is due to the A-flex feature that reduces the pressure every time I exhale. I would say that this is one feature that definitely saves on batteries..
