摘要：
An inhalation anesthesia delivery system and method, wherein the system includes a fresh gas feeding arrangement connected to a breathing circuit, a monitor device, a control device and an interface unit. The fresh gas feeding arrangement is configured to deliver a desired concentration of gas to the breathing circuit, the desired concentration being set by using the interface unit. The monitor device is configured to monitor gas concentrations in the breathing circuit by analyzing gases flowing in the breathing circuit, and the control device is configured to control the fresh gas feeding arrangement on the basis of the data received from the monitor device to keep the desired breathing gas concentration. The control device is also 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.
