A vaporizing system for closed circuit programmed anesthesia is described. Despite its location within the circuit, the vaporizer controls directly the input of volatile anesthetic agents irrespective of fluctuations in ventilation of the anesthetized subject. It is interfaced easily with electronic controllers and has an accuracy approaching 1.0% under laboratory conditions. During experimental anesthesia, it maintained stable end-tibial concentrations of halothane at 1.2 MAC (the intended value) despite wide variations in ventilation.
