What is a pressure bandage primarily used for?

A pressure bandage is primarily used to stabilize a wound and maintain pressure on it, effectively helping to control bleeding. This type of bandage works by applying direct pressure to the injured area, which can minimize blood loss by constricting blood vessels and reducing the flow of blood to the site of the injury.

In trauma situations, creating a stable environment for the wound can prevent further injury and facilitate better healing conditions. This is particularly important for managing lacerations, puncture wounds, or any injuries where bleeding is present. Proper application of a pressure bandage can also encourage the formation of a clot and support the overall healing process.

The other options do not accurately define the primary purpose of a pressure bandage. For instance, while a tourniquet effect might be necessary in severe cases, it is a different technique involving tighter application and is not the role of a standard pressure bandage. Additionally, cooling the area of the wound is relevant for different types of injuries, such as burns or sprains, rather than the primary goal of a pressure bandage. Lastly, promoting active bleeding would be counterproductive in the context of a wound, as the purpose of a pressure bandage is to minimize bleeding rather than encourage it.
