Methods and apparatus for adjusting blood circulation

A device for controlling body temperature of a patient, comprising:

• a plenum having one or more walls that define an internal pressure region, wherein at least one of the one or more walls form an enclosed region that is on a side of the at least one wall that is opposite to a side on which the internal pressure region is disposed, and the enclosed region is adapted to receive a portion of a patient;
• one or more thermal exchanging units that are disposed between the one or more walls and the portion of the patient;
• a first device that is adapted to create a pressure above atmospheric pressure within the internal pressure region of the plenum to urge the one or more thermal exchanging units against a surface of the portion of the patient;
• a vacuum pump that is coupled to the enclosed region of the plenum and is adapted to create a pressure below atmospheric pressure within the enclosed region;
• and
• the device for controlling body temperature further comprising a third device that is in fluid communication with an internal region of an inflatable cuff which is positioned over a portion of the extremity, wherein the third device is adapted to adjust the pressure in the internal region of the inflatable cuff.
