A rapid measuring system for the determination of the concentration of propofol in the respiratory flow, which can be designed in a compact form, has the features of a breathing gas line ( 1 ) including a breathing gas sensor ( 2 ) detecting the respiration, wherein the breathing gas sensor ( 2 ) is connected to an evaluating unit ( 3 ), a propofol sensor ( 5 ) with a downstream pump ( 6 ) is in gas flow connection with the breathing gas line ( 1 ), wherein the evaluating unit ( 3 ) is connected with the propofol sensor ( 5 ) and the pump ( 6 ), so that the evaluating unit ( 3 ) actuates the pump ( 6 ) for breathing gas sampling depending on the signal of the breathing gas sensor ( 2 ), and the propofol sensor ( 5 ) sends a measured signal for the concentration of propofol in the breathing gas to the evaluating unit ( 3 ). |
