An anesthesia system (2), comprising a fresh gas source (14) for supplying a defined flow of fresh respiratory gas to a respiratory circuit (22), is described. The flow is regulated by a flow valve (20) which is controlled on the basis of a flow measured by a flow meter (18). The anesthesia system (2) is devised so the flow meter (18) can be calibrated while the system is in operation to permit the supply of a continuous, or largely continuous, flow of fresh respiratory gas to the respiratory circuit (22). <MATH> |
