A scavenging device for the Bennett BA–4 “Anaesthesia Ventilator “is described. Anaesthetic gases are vented outside the operating theatres by means of Venturi-type suction apparatus. The unit is very efficient under normal working conditions and no interference with ventilator function has been observed.
