An Anaesthetic gas flow regulator control means including a plurality of electrical outputs for controlling the actuation of valves for flow of oxygen and anaethesia gas, said control means providing an "oxygen" signal when a predetermined oxygen concentration has been reached and a "volume" signal when an oxygen or anaesthesia gas is required, said "oxygen" and "volume" signals being gated to provide an output to one of said valves to cause flow of either oxygen or anaesthesia gas. |
