A measuring head for the analysis of respiratory gases to and from a patient connected to a respirator, includes an aperture ( 7 ) which is intended to be placed over an adapter ( 2 ) through which respiratory gases flow. The measuring head ( 1 ) has a light transmitter ( 9 ) which includes an IR-emitter ( 12 ) on one side of the aperture ( 7 ) and a light receiver ( 10 ) which includes an IR-detector on the other side of the aperture ( 7 ). The measuring head ( 1 ) also includes a signal processing unit ( 20 ) necessary for the gas analysis. |
