Abstract
An anaesthetic delivery system has a ventilation arrangement with an inspiration gas pathway for conducting inspiration gas to a patient and an expiration gas pathway for conducting expiration gas away from the patient, and a filter element serially connected to both the inspiration and the expiration gas pathways. The filter element retains anaesthetic from expiration gas passing therethrough and releases the retained anaesthetic into inspiration gas passing therethrough. A supply of flushing gas is communicable with the filter element to flush the retained anaesthetic from the system without passing to the patient.
