The mouth piece according to the present invention comprises a housing comprising a mouth piece breathing part opening for inhaling and exhaling a breathable gas. An inlet port for providing breathable gas into said mouth piece housing, the inlet port being in communication with valve means arranged to open or close said inlet port. The housing further comprises a first exit port for exhausting gas from said housing into a closed circuit flow channel and a second exit port for exhausting gas from said mouth piece housing into an ambient environment. Switch means for selectively directing said exhaust gas between said first exit port and said second exit port to change the mouth piece between open circuit breathing and closed circuit breathing.
