What Is a Wound Vac?
Vacuum-assisted closure (VAC) of a wound is a type of therapy to help the wound heal by decreasing air pressure around a wound. Also known as Negative Pressure Wound Therapy, a healthcare professional/Wound Care Specialist applies a special dressing (bandage) is sealed over the open wound and a vacuum pump is attached that creates negative pressure around the wound and pulls the edges of the wound together to help the wound heal in several ways. In simple words, the wound vacuum device removes air pressure over the area of the wound and keeps it lower than the pressure in the atmosphere. This helps reduce swelling and clean the wound by removing bacteria.

How Does Wound Vac Therapy Work?
This wound vac therapy includes a vacuum pump, a special bandage for dressing, a canister to collect drainage, and tubing. Firstly, the Wound Care Surgeons will cover your wound with a foam or gauze wound dressing sealed with a thin layer of film. There is an opening in the film that connects to a drainage tube which leads to a portable vacuum pump. When the pump is turned on, it draws fluid and infection from the wound through the foam and also pulls the edges of the wound together. The pump may run all the time or in cycles. It depends on the type of wound vacuum system used.
The undergoing person wears the device for almost 24 hours per day while they are healing. The dressing needs to be changed once a day or more often depending on the type of wound. You or your caregiver will be trained by wound care experts to do this at home or it may be done by themselves.
