A compression bandage is a type of medical dressing designed to apply pressure to a specific area of the body. It is commonly used to support injured limbs, reduce swelling, and improve blood circulation. These bandages are often made from elastic materials, allowing them to stretch and conform to the shape of the body. Compression bandages are frequently used in the treatment of conditions such as sprains, strains, and venous insufficiency. They can also be applied after surgeries to minimize swelling and promote healing. Proper application is essential to avoid restricting blood flow, so it's important to follow medical guidelines when using them.
