A hood assembly placeable over a person's head for treating a person with a gas such as oxygen. Basically the assembly includes a resilient neck ring around a user's neck, a soft, rubbery, tubular neck seal with one end connected to the neck ring and the other configured to fit around the user's neck and a transparent hood fastened to a hood ring that can be sealed against the neck ring. Tubes direct gas into and out the hood through ports through the neck ring. Preferably, the seal that engages the neck is marked with indicia showing a series of varying circumferences, so that the neck seal opening can be trimmed to provide a comfortable and sealing circumference for engaging the user's neck. The assembly is particularly adapted to use in providing oxygen to a patient in a hyperbaric chamber.
