What is the purpose of a wound VAC?

A wound VAC, or vacuum-assisted closure device, is specifically designed to apply negative pressure to a wound. This negative pressure creates a vacuum effect that helps to draw the edges of the wound together, promoting faster healing. The mechanism encourages the formation of granulation tissue, which is essential for the wound healing process. It also helps to remove excess fluid and exudate, decreasing the risk of infection and promoting an optimal healing environment.

While other options such as administering medication, applying heat, or cleaning and disinfecting a wound are essential aspects of wound care, they do not define the primary function of a wound VAC, which is to facilitate healing through the application of negative pressure. This targeted approach to wound management can be especially beneficial for complex or slow-healing wounds.
