Abstract
A low air loss therapeutic air support system which simultaneously prevents the development of pressure sores and skin maceration due to the build up of heat and moisture at points of interface between the device and the patient and has an active feedback system which provides for real time adjustments to the inflation pressure of the support surface in response to an increase in the compressive pressure on a part of the support surface from shifting of the patient's position or other causes which can be used interchangeably with a sleeping surface and a wheelchair seating system.
