Abstract

An oxygen mask comprising a mask face piece to cover the nose and mouth of a user, said face piece having at least one one-way inhalation valve, and an one-way exhalation valve, a chamber having an inlet port connectable to an adjustable supply of oxygen, and outlet port, and apertures in the chamber wall connecting the inside of the chamber to ambient air, and a conduit connecting the chamber outlet port to a face piece inhalation valve, in use oxygen enters the chamber displacing ambient air in the chamber through the apertures during the exhalation cycle of the user's lungs, and oxygen is drawn out of the chamber through the conduit and through an inhalation valve during the inhalation of the lungs.
