We had enough problem with infection control issues when they were in use,
let alone giving them to another person.
However, if you are using a spittle trap which can be demonstrated to be
effective, and the sensor you are using can be effectively decontaminated -
although I am not sure how you prove that, then if the actual sensor is very
costly, it may be worth trying.
Systems these days seem to use an isolating diaphragm, so that breath from
the user never gets to the sensor element.
I do remember once opening up an old sip/puiff switch unit, it was pretty
gungy inside.
On the whole it would seem to be safer to discard the older units in favour
of the isolated diaphragm type.

Subject: Refurbishing Sip/Puff Switches?
I'm writing regarding sip/puff switches.
We regard them as clinical waste when they are no longer required. We
dispose of them as such. As they are expensive to buy I accept this seems
wasteful. However, given the risk of infection I don't see how they can be
reused safely even after the mouthpiece is replaced.
There is also the option of refurbishing the switch by completely replacing
the mouthpiece, tubing, switches etc.
I'd be very interested to find out how other departments deal with sip/puff
switches when they are no longer required. Do any of you refurbish them?
regards
