Mask Setting

[Joe Bezz]

Does anyone know exactly what changes when you switch you machine settings from Nasal, to Full Face mode?

I'm curious, too, and speculate that if the machine thinks you have one type of mask but you are wearing another then it's not delivering the pressure that it thinks it is. If you are in autoset mode it's probably not a real issue -- the way the machine works is that if it decides the pressure needs to be higher it raises it and if the pressure should be lower it lowers it. If the machine is wrong about what those pressures were but they are the right pressures to treat whatever is happening, then not knowing the numbers is academic.

...But one thing I do know is that with the N30i you should use the "pillows" not "nasal" setting.
