Abstract:
A breathing device, comprising:a breathing gas delivery device; a gas supply line for breathing gas; a breathing gas line connected via said breathing gas delivery device to said gas supply line; a gas sensor for measuring a breathing gas component in said breathing gas line, a bypass line extending from said breathing gas line to said gas supply line; a measuring gas line with an eletrochemical measuring cell gas sensor generating a gas value signal, said measuring gas line being provided in parallel to said bypass line; a throttling point provided in the course of said measuring gas line between said electrochemical measuring cell gas sensor and said breathing gas line; a pressure sensor located downstream of said electrochemical measuring cell gas sensor, said pressure sensor generating a pressure value signal; a measuring gas line and gas supply line junction point provided upstream of said bypass line; a control unit forming a correction value for said gas value signal with said pressure value signal.
