Beschreibung
Zusammenfassung:	A device with a gas sensor for measuring a breathing gas component in a breathing gas line is improved such that a pressure correction of the gas concentration measurement can be performed without appreciably affecting the respiration pressure. Provisions are made for branching off a first measuring gas line (23) with a first electrochemical measuring cell (28) from the breathing gas line (7). A first throttling point (26) is arranged in the course of the first measuring gas line (23) between the first electrochemical measuring cell (28) and the breathing gas line (7). A first pressure sensor (29), for the pressure correction, is located downstream of the first electrochemical measuring cell (28).
