What is the purpose of surgical (elastic) hose?

Surgical (elastic) hose, also known as compression stockings, primarily serve to support leg veins and enhance circulation. This type of hosiery applies graduated compression to the legs, which helps to promote venous return—the process of blood being sent back to the heart from the lower extremities. By exerting pressure on the veins, these stockings can reduce the diameter of distended veins, thereby minimizing the pooling of blood and preventing the formation of blood clots. They are particularly beneficial for individuals who may have chronic venous insufficiency, those post-surgery, or people who spend prolonged periods of time sitting or standing.

While the other options may cover some general benefits related to health care practices, they do not accurately reflect the primary function of surgical hose. For instance, while support for healing wounds is important in many contexts, it is not the primary purpose of this specific type of hosiery. Similarly, although preventing infection is vital in medical care, surgical hose specifically does not serve this function. Orthopedic alignment relates more to joint positioning and stability, not directly to circulation or venous support. Thus, the correct understanding of the role of surgical (elastic) hose is centered on their ability to support leg veins and effectively improve circulation.
