Abstract
A device for administering a mixture of oxygen and a second gas to a patient premeasures and temporarily stores single dose quantities of each gas and dispenses each dose in synchronization with the patient's respiratory cycle. A sensor produces a signal upon the onset of an inhalation and, in immediate response to the sensor signal, the dose quantities of each gas are simultaneously displaced into a common conduit for breathing by the patient.
