There should be no flow at the common gas outlet. Isoflurane and oxygenair combinations for maintenance of anesthesia were delivered through the UAMs vaporizer and draw-over system.

A modern derivative of open-drop anesthesia utilizes draw-over vaporizers that depend on the patients inspiratory efforts to draw ambient air through a vaporization chamber. Configuration of Draw-Over Anaesthetic Breathing System Anaesthesia.
