You knew somebody was going to do it. At a pressure of 20, which is the limit of most xpap's, the pressure is equivalent to .284 PSI, not even enough to blow up a balloon.
As you see in the attached picture, my old 3 button remstar set at 20, only fills up the shape of the uninflated balloon. It does not have enough pressure to blow the balloon up.
Now we know. It's unreal to me all the problems we have adjusting to this little pressure and how strong it feels when we don the mask and crank 'er up.
