Lay Explanation of the Action from the Circulator Boot
A leg with poor arterial blood flow may be likened to a dirty sponge that is half wet. Squeezing such a sponge disseminates the water throughout the sponge. Soaking and wringing the water repeatedly from the sponge may help clean it. In like fashion, the heart monitor of the Circulator Boot™ is timed to allow each arterial pulse wave to enter the leg as best it can (to partially wet the leg "sponge"). Boot compressions provide a driving force to disseminate blood around the leg and at the same time press venous blood and excess tissue water from the leg. Patients with a pulse rate of 80 beats per minute might receive 4800 such compressions an hour. Patients with severe arterial leg disease might receive 100 such treatments or close to a half million compressions! Breakdown of clot, rechannelization of blocked vessels and the formation of new small vessels may help restore blood flow.
