An anaesthetic vaporizer is a device generally attached to an anaesthetic machine which delivers a given concentration of a volatile anaesthetic agent. It works by controlling the vaporisation of anaesthetic agents from liquid, and then accurately controlling the concentration in which these are added to the fresh gas flow.
