My advice would be to ignore it and use the Aura and see how you go! The pressures might be a little different, but it probably will be just fine
That would be my non-doctorly advice too...same as Sir_C.
There could very well be
some people whose breathing patterns could be misread by one autopap but read fine by another, or misread by
any autopap, depending on what mask they were wearing -- expecially when it comes to the narrow diameter hose masks. Not an issue at all, I don't think, with the PB 420E machines regarding narrow diameter hoses since the Breeze and 420E are "made" for each other. I do think
most people can wear
any mask they happen to like, with
any autopap -- and get good treatment.
Given how important finding a comfortable mask is to getting treatment at all, I'd not worry about the "warning". I'd give
any mask a try with whatever autopap I was using, to see how I felt the next day. And I wouldn't get concerned if the data showed extra tick marks as long as the machine was behaving reasonably well (not running up to the top pressure when it usually doesn't do that) and was giving me good treatment. Nor would I worry if some masks made the data show up with a slightly higher AHI, as long as it was reasonably low (5 or under for the AHI.)
I've used both the Breeze and the Aura (and briefly the Swift) with all three major brands of autopap - no problem for me with any of the mix and match combos. I've been using my chopped down Aura and Respironics REMstar Auto with C-flex for quite a few months now. Getting good sleep, as usual.
