Someone please help me understand Mask Pressure. I see it as low as 2.4 and sometimes as high as 32.2.

That's your machine's best guess at the pressure in the mask. It takes into account what it has been told about hose diameter and length as well as mask type. The machine is constantly trying to keep that pressure at your prescribed setting. There is no pressure sensor in the mask, or even at the hose end, so basically this can be regarded as the error the machine thinks it saw during its attempts. You may have noticed that you can 'fool' the machine by coughing or drawing very hard, this will cause those excursions.

Thank you. I do have some coughing at times. So it is not one of the important things to consider. What would you say are the important graphs to look at?
