[Expiratory air diversion during general anesthesia (author's transl)].
A system for disposing of expiratory air containing volatile anaesthetic gases during anaesthesia is described. It consists of a reservoir bag and an adjustable suction connected to the outlet port of the anaesthesia machine or the nonbreathing valvel. A valve is incorporated which opens to the atmosphere if the reservoir bag should collaps completely, thus creating a slight vacumn in the system. Another valve, opens if the bag should become fully expanded and a slifht positive pressure develop in the system. Halothane concentrations in the "anaesthetists breathing zone" were negligible when this system was being used.
