An oxygen adapter for delivering low volume supplemental oxygen to a tracheostomized patient using a conventional tracheostomy speaking valve is provided, the adapter including a tube fitting for receiving conventional tubing thereon, and an outlet section attached to the tube fitting and defining a channel communicating between the tube fitting and an outlet end of the outlet section. The outlet section preferably extends axially from the tube fitting along the outer wall of a speaking valve to which the adapter is connected, the outlet end being located adjacent an inlet of the speaking valve, thereby delivering oxygen from the tubing received on the tube fitting to the inlet of the speaking valve. The adapter may be detachably connectable to the cylindrical wall of the speaking valve, preferably by a pair of semi-rigid gripping flanges adapted to peripherally engage the cylindrical wall of the speaking valve. The adapter preferably comprises injection-molded plastic, such as polycarbonate.
