In 1960 the arrival of new halogenated anaesthetic agents led to the abandonment of former agents such as ether, chloroform, ethyl chloride and cyclopropane over the following years. The Fluoxair machine (1967) was a compact, portable self – contained open circuit device allowing the administration of halothane, air and oxygen. The patient could either breathe spontaneously or be given assisted ventilation manually using a bag. Commercially, the device could be adapted for use with chloroform. The original machine, built by the British company Cyprane Ltd was distributed by the LSA company in France which no longer exists.
