Yes, barometric pressure.

It's the *difference* between ambient air pressure and the pressure the PAP gives to you that keeps the airway open, not the absolute figures.

Normal changes in outside ambient air pressure will be meaningless so far as the effect your machine is giving you.

1cm/water pressure is very nearly equal to 1 millibar of atmospheric pressure, which is about 1/10th of 1% of normal atmospheric pressure at sea level. Even at 20cm which is the max for most machines is a difference of only 2% between the outside pressure and the pressure from the machine in your airway.

The above is my opinion.  It is just possible that I may, occasionally, be mistaken.

I am neither a Doctor, nor any other kind of medical professional.

Everything put together sooner or later falls apart.

A change in the barometric pressure may trigger "a bit of the old ultra violence".
