Re the pipe.
You could use a differential pressure transducer.
One side is attached/inserted into the side of the mask, the other extends
through the side of the mask ending up in front of the users mouth/lips.
There would be no net differential pressure on the transducer unless the
user closed around their mouth tube and blew/sucked.
Theoretically there would be no loss of pressure to the vent mask either.
I have never done this but it feels like it should work!
Good luck,

Subject: suck switch for nippv patient
Dear all
Has anyone tried to use a suck switch with someone who has a nippv
ventilator via a mask? I be grateful for any experience shared.
There are lots of issues about how to get the tube inside the mask, does he
have lip closure/suction, but is there anything about the nippv action which
would preclude it?
