Abstract
A method for augmenting blood flow in a limb that is wrapped with a sleeve having at least one chamber for applying compression to the limb in a region generally underlying the chamber includes pressurizing the chamber to a first compression pressure and then reducing the pressure to a refill pressure. Pressure in the chamber is then sensed to determine a first venous refill time. The preceding steps are repeated a second and other times using second and other compression pressures that are different from the first compression pressure and from each other to determine second and other venous refill times. A customized compression pressure is determined by locating the compression pressure at which blood flow out of the region generally underlying the chamber is maximized by finding compression pressure at a maximum venous refill time. A compression device employing such a method is also disclosed.
