ABSTRACT:
Air is supplied directly to the area of a subject's nose and mouth when he or she lies on a pillow, through a device which has a plurality of inflatable valve-chambers located under the pillow, so that when the subject's head rests on one of the areas and on one of the valve-chambers the latter is deflated, while another valve-chamber is inflated to let the air from its associated passage exit through its associated outlet directly towards the subject's face.
