Effects of compression therapy for the human organism

The compression of extremities such as the leg with bandages, stockings, or other means leads to the formation of a pressure gradient from superficial tissue areas to the underlying areas, leading to a 1.5-fold increase of venous flow rate. It has been found 

The increase of external pressure on the body parts from compression increases the rate of blood flow. In addition to increasing venous return, it also affects arterial flow regulation by increasing hyperanic peak flow. 

The compression of extranities, especially the legs, leads to a significant relocation of liquids from the periphery to central body parts. This increases the preload of the heart and, in the worst cases, excess relocation of liquids can cause central hanodynamic effects and lead to cardiac problems. 

In the human body, the soleus is a powerful muscle in the back part of the lower leg, i.e., the calf. It runs from just below the knee to the heel, and is involved in standing and walking. In the upright posture it is responsible for pumping venous blood back into the heart from the periphery, and is often called the skeletal-muscle pump or peripheral heart. The reduction of vein diameter by means of compression bandages helps to improve the function of the muscle pump by enhancing the efficiency of the reverse flow.
