ABSTRACT:
A reliable, pulse-flow supplemental oxygen apparatus for alleviating respiratory ailments is provided which yields substantial savings in oxygen while giving the patient the physiological equivalent of a prescribed continuous stream of oxygen. The apparatus preferably includes a demand oxygen valve operated in a pulse mode by means of electronic control circuitry which, through an appropriate sensor, monitors the patient's breathing efforts and gives a variable "custom tailored" pulse volume of oxygen to the patient during the very initial stages of each inspiration.
