What is the main purpose of using compression stockings in patients at risk for DVT?

The primary purpose of using compression stockings in patients at risk for deep vein thrombosis (DVT) is to improve venous return and reduce stasis. Compression stockings exert graduated pressure on the legs, which promotes the flow of blood back toward the heart. This helps prevent the pooling of blood in the lower extremities, a critical factor in the formation of blood clots. By enhancing venous return, these stockings reduce the chances of stagnant blood flow, significantly decreasing the risk of DVT, particularly in populations susceptible to this condition, such as individuals undergoing surgery or those who are immobile for extended periods.

While other options touch upon aspects related to circulation and health, they do not directly address the mechanism by which compression stockings work to prevent DVT. Astute recognition of this targeted approach is crucial for understanding the role of compression in thrombotic prevention.
