How does a pressure bandage assist in the treatment of a wound?

A pressure bandage plays a crucial role in wound treatment primarily by holding dressings in place, which is essential for effective wound management. This secure placement of dressings helps to protect the wound from external contaminants, reduces the risk of infection, and promotes optimal healing conditions by ensuring that the dressing adheres properly to the wound site.

In addition to holding dressings in position, pressure bandages can also apply a controlled amount of pressure to help control bleeding, which indirectly supports the healing process. However, it is the function of securing the dressing that is paramount. Other options, such as promoting dehydration or increasing blood flow, do not align with the purpose of a pressure bandage. Preventing clot formation is contrary to the intended outcomes of wound care, as clotting is a vital part of the healing process. Hence, the primary purpose of a pressure bandage is to keep the dressing securely in place to protect the wound effectively.
