摘要： A process and system are provided for controlling a respirator with a breathing circuit (2), an inspiration branch (10) and an expiration branch (12), in which the gas components needed for the respiration are fed in by a fresh gas metering device (20) via a fresh gas line (9), as a result of which at least the amount of breathing gas consumed can be replenished. A breathing gas delivery unit (1) is provided in the inspiration branch (10) and with a volume flow sensor (13) in the expiration branch (12). The fresh gas utilization of the respirator is improved and the process and system reduces the resistances in the breathing circuit (2) for the patient (3) by the breathing gas delivery unit (1) being returned during the phase of expiration at a speed that depends on the volume flow that is measured by the volume flow sensor (13). A maximum percentage of the breathing gas volume expired via the expiration branch (12) reaches the breathing gas delivery unit (1) and can be displaced from there to the patient (3) via the inspiration branch (10).
