An apparatus and method for performing warming therapy is described. In one exemplary embodiment, the apparatus includes a patient support assembly and an air circulation system coupled to the patient support assembly, which includes first and second air flow channels which are separate from one another. The first and second air flow channels may be separately activated, depending upon the air flow required. Additionally, the elements of the air circulation system are easily disassembled, so as to allow easy cleaning of the system which, in turn, maintains a sterile patient environment.
