An oxygen management device adapted to mount on a post on a compressed oxygen cylinder. The device includes a manifold block which is attached to the oxygen cylinder post. A pressure regulator is mounted directly on and is integral with the manifold block for reducing the oxygen pressure to a desired level. The manifold block also mounts an overpressure relief valve, a solenoid operated flow control valve, a bypass valve, a continuous flow restrictor and a pressure gauge. The manifold and the components mounted thereon, a control circuit and a battery for operating the control circuit are mounted in an annular housing which has a central opening for receiving the oxygen cylinder post. The control circuit senses when a patient inhales in a nasal cannula and opens the flow control valve to deliver a predetermined dose of oxygen to the nasal cannula at the beginning of inhalation. The volume of the low pressure oxygen passages in the manifold block are minimized to enhance the responsiveness of the device in delivering a dose of oxygen to a patient.
