[The development of vaporizers. A question of precise dose].
Since the beginning of anaesthesia it was well known that anaesthetic agents administered by inhalation must be capable of existing in gaseous form. For vaporization various types tried to work accurately. Since oxygen was available there could be realized new concepts like the principles of injection or bubble through. With Copper Kettle (1948) for ether and chloroform and Draeger Vapor (1958) for Halothane accurate administration of volatile anaesthetics was available. Today vaporizers are part of anaesthetic machines.
