What is the primary purpose of using a compression bandage on an injury?

The primary purpose of using a compression bandage on an injury is to control swelling and bleeding. When applied correctly, a compression bandage exerts pressure on the injured area, which helps to minimize the amount of blood that leaks from damaged blood vessels. This control is particularly crucial in situations involving soft-tissue injuries, where excessive swelling can complicate treatment and recovery.

By compressing the area, the bandage also helps reduce the accumulation of fluids, thereby lessening swelling. This action is important because it can prevent complications such as compartment syndrome, which can occur when swelling leads to increased pressure within a confined space in the body.

While the other options do have their own importance in injury management, they do not align with the primary function of a compression bandage. Immobilization is typically achieved with a splint or support bandage, air circulation is generally not a primary concern (and might even be counterproductive, depending on the injury), and keeping the wound clean and dry requires different techniques such as dressing rather than compression itself.
