1. An arrangement for the analysis of respiratory gases provided to and from a patient connected to a respirator, comprising:
a holder unit for a removably fitted water trap that is adapted to receive said respiratory gases, and
a connection that is adapted to provide liquid-free gas from the water trap to an analysing instrument to which analysing instrument the holder unit is connected, wherein
said holder unit includes an oxygen gas measuring unit for measuring oxygen gas in the liquid-free gas,
said oxygen measuring unit receives the liquid-free gas after analysis of the liquid-free gas by the analysing instrument, and
said oxygen gas measuring unit is a fuel cell which is removably attached to said holder unit and has a connection that is adapted to receive the liquid-free gas from the analysing instrument via said holder unit.
