Abstract

The present invention relates to a measuring head for the analysis of respiratory gases to and from a patient connected to a respirator, wherein the measuring head includes an aperture (7) which is intended to be placed over an adapter (2) through which respiratory gases flow, wherein the measuring head (1) further comprises 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 said aperture (7), and wherein the measuring head (1) also includes a signal processing unit (20) necessary for the gas analysis.
