I agree with the recommendation about determining your set pressure on a nasal mask, especially if you are concerned about the function of your machine.

Full face masks often push the lower jaw back, so it is not uncommon to find that a lower pressure is needed on a nasal mask in comparison to a full face. Also, many patients switching from a full face mask to a nasal perceive a higher pressure build up in the mask even at the same pressure. This feeling goes away with time.

It is true that the clinical manual does not have instructions for how to interpret results. I suppose this is because different sleep clinics use different methods and because much of sleep technology training is on the job. Resmed, for example, run workshops for clinicians on a regular basis.

Lastly, I believe the algorithms for all autoset devices have all been released. While their descriptions are never in sufficient detail the latest clinical manuals for Resmed and Respironics have the algorithms in them.
