Zusammenfassung:	Inhalation anaesthesia delivery system and method, comprising a fresh gas feeding arrangement (13,14) connected to a breathing circuit (3), a monitor device (15), a control device (17) and an interface unit (18). The fresh gas feeding arrangement and the ventilator are configured to deliver a desired concentration of gas to the breathing circuit, the desired concentration being set by using the interface unit (18). The monitor device (15) is configured to monitor gas concentrations in the breathing circuit by analysing gases flowing in the breathing circuit, and the control device (17) is configured to control the fresh gas feeding arrangement on the basis of the data received from the monitor device (15) to keep the desired breathing gas concentration. The monitor device (17) is configured to monitor expired inorganic gas concentration by comparing the measured expired breathing gas concentration with the set target value and changing the fresh gas delivery accordingly to meet the target value.
