Final answer:
Three critical aspects of using a compression bandage are protecting the injured area, compressing to reduce swelling and provide support, and elevating the limb to minimize blood pooling.
Step-by-step explanation:
Three important aspects of applying a compression bandage are protection, compression, and elevation. First, applying soft padding provides protection and aids in minimizing impact with objects that might cause further injury. Secondly, a properly applied bandage creates compression which is essential to reduce swelling and provide support to the affected area. Lastly, elevation of the injured limb above the level of the heart helps in reducing the chances of blood pooling and further swelling in the injured muscle.
