What is the primary function of compression hose?

The primary function of compression hose is to prevent swelling and assist in the upward movement of blood. These specialized garments are designed to apply graduated pressure to the lower extremities, which helps to promote venous return and reduce the pooling of blood in the legs. This function is particularly important for individuals who may be at risk for conditions such as deep vein thrombosis or chronic venous insufficiency.

By applying pressure, compression hose help to strengthen the walls of the veins, thereby enhancing blood circulation and reducing the likelihood of swelling or discomfort. This function is essential for maintaining overall vascular health, especially in individuals who spend long periods sitting or standing, or those with certain medical conditions.

The other options do touch on aspects that may be seen in specific situations but do not encompass the primary purpose of compression hose. For instance, improving oxygen delivery pertains to respiratory function and is not a direct effect of compression garments. Enhancing athletic performance may be a perceived benefit of some compression garments, but this is not their primary design intention. Finally, while mobility can be indirectly improved due to less swelling and discomfort, the main focus remains on preventing swelling and aiding blood flow.
