Abstract: A mattress assembly for supporting a patient includes a body support portion having a head end, a foot end, and a knee support portion. The body support portion has a first air zone extending from the head end to the knee support portion and a second air zone extending from the knee support portion to the foot end. The mattress assembly also includes a control module configured to supply air to the first and second air zones to maintain the first air zone at a substantially constant first pressure and to maintain the second air zone at a substantially constant second pressure. The second pressure is less than the first pressure to provide reduced pressure on a patient's calves and feet located on the second air zone.

Abstract: The present invention relates to a vibratory patient support system for providing therapeutic vibrational action or forces to a patient suffering from a respiratory ailment. The vibratory patient support system includes a rigid support frame such as a bed frame, a plurality of inflatable sacs supported upon the support frame with each sac having an upper surface so that the plurality of sacs forms a patient support surface. The inflatable sacs are pressurized and maintained at a predetermined pressure. This predetermined pressure may be a patient height and weight specific pressure profile. A vibrating component is provided separate from the apparatus for pressurizing and maintaining the air sacs at the predetermined pressure. The vibrating component vibrates at least a portion of the patient support surface at a predetermined frequency.
