An inflatable patient support has an array of inflatable tubes made of flexible material and divided into a plurality of groups which are supplied with air by first air supply means to cause cyclic inflation and deflation of the groups of said array of inflatable bodies in sequence, thereby providing periodic pressure variation to a patient on the support. A flexible ventilation air guide member (10) is provided on the array of tubes and has at its upper side a plurality of outlet apertures (6) for release of ventilation air upwardly to the patient on the support. Second air supply means supply air continuously to the flexible ventilation air guide member for release as the ventilation air. The ventilation air is thus independent of the pressure cycling air supply, and can be for example heated. <IMAGE> |
