More Information
Summary:An anesthetic dispensing device (100) includes a measuring unit (150) for determining an anesthetic concentration in an area of an outlet (142) of the anesthetic dispensing device. The measuring unit is configured to measure a first parameter (154) of a gas concentration-dependent characteristic between a mixer unit (140) and a second parameter (155) of the gas concentration-dependent characteristic in a second gas branch (120) or in an area of a breathing gas feed (112) of the anesthetic dispensing device by at least one sensor element (152). The measuring unit is further configured to determine the anesthetic concentration between the mixer unit and the outlet and to output a corresponding concentration signal (160) as a function of calibration information assigned to the second parameter and of the first parameter.
