摘要： An anesthetic breathing apparatus has a first gas analyzer arranged to provide gas measurement data related to a first sample point to a control unit that is arranged in a servo or feedback control system configured to adjust delivery of a vaporized anesthetic agent from an anesthetic vaporizer to a delivery point in an inspiratory branch of a breathing circuit of the anesthetic breathing apparatus, The first sampling point is arranged in the breathing circuit downstream and close to the delivery point. A second gas analyzer arranged to be operated in a first mode of operation to provide gas measurement data for patient monitoring, and arranged to be operated in a second mode of operation to provide gas measurement data to the control unit. A switch over unit is fluidly connected to the second gas analyzer, and arranged to switch fluid communication of said second gas analyzer between the first sample point for the second mode of operation and a second sample point for the first mode of operation. The second sample point is arranged in a patient tubing close to a Y-piece at a patient connected to the breathing circuit.
