ABSTRACT:
A facial support cushion for supporting the face of a person lying in a prone position, wherein the cushion is an annular, generally torus shaped body having a hollow interior with a plurality of generally radially extending partitions extending across the interior of the body, dividing it into a plurality of individual chambers spaced sequentially around the body. Apparatus is connected with the chambers to sequentially expand and contract them in an alternating pattern so that some of the chambers are expanded to contact and support the face while other chambers are contracted to relieve the pressure exerted against the face by the other chambers, whereby the formation of pressure sores and other deleterious effects are avoided by periodically and temporarily relieving pressure exerted by the chambers against different areas of the face.
