With my Mirage Quattro and set at full face mask type, the transitions between my 16 cm EPAP and 20 cm IPAP are as smooth as silk. When I used the Pilairo Q with the mask type set for "pillows". the pressure transitions became rather sharp and abrupt.
Once I forgot to set the mask type back to full face when I went back to my Mirage Quattro. The pressure transitions were still sharp and abrupt and had my ffm doing mini pushups on my face. I corrected the setting and it became very smooth.
Out of curiosity, I tried the Pilairo Q with the type setting at full face and got very nice, smooth transitions.
Does anybody know why the full face setting gives me smooth transitions and the pillows setting does not? Can anyone think of any problems that might arise from using a nasal pillows mask with the full face mask type setting? I have not really thought it through but at face value this situation does not make a lot of sense to me.
