Fluorinated hydrocarbons have transformed inhalational anaesthesia, and vaporizers are essential for safe and accurate delivery of these agents. The modern day vaporizers have evolved considerably since the ether inhaler invented by John Snow in 1847 and are robust, precise and efficient. For an anaesthetist to administer safe inhalational anaesthetic, it is important to understand the physical principles of the various inhalational anaesthetic agents along with the working principles of the vaporizers. Almost all modern vaporizers are located outside the circle system and the have multiple safety mechanisms in place.
