A combination patient-transfer and intraoperative heater has top and bottom chambers separated by a barrier. The patient rests on the top chamber, which has plural apertures for discharge of temperature-controlled heated or cooled air at regulated pressure. Heated or cooled air is delivered to the area surrounding the patient, maintaining body temperature during anesthesia. The bottom chamber has plural apertures. When air pressure is low or off, the bottom chamber is flat and un-inflated. When air pressure is increased, air enters the bottom chamber and the apertures emit air, creating an air cushion facilitating lateral movement of the lifter device. The device is light, flexible, easily stored, and preferably disposable, thereby reducing risk of infection and avoiding cleaning costs. The device performs two functions that now require separate devices and air blowers, it saves space and reduces both costs and complexity in the operating room.
