An apparatus for applying compression therapy to a portion of the human body includes a flexible member and an air bladder chamber. The flexible member is adapted to wrap around the body portion to secure the air bladder chamber thereto. An air pump inflates the air bladder chamber to a pressurized state. An adjustable pressure regulator is fluidly coupled to the bladder chamber and automatically limits the pressure to a selected amount. The pressure regulator preferably includes a plurality of check valves, each being operable at a different pressure and a selector element. The check valves are fluidly coupled to the selector and the selector is fluidly coupled to the bladder chamber. Operation of the selector fluidly couples one of the check valves to the bladder chamber. According to the presently preferred embodiment, three check valves are provided, operable at 20 mmHg, 30 mmHg, and 40 mmHg.
