About VAC Treatment

What is VAC therapy ? 

Vacuum Assisted closure therapy (VAC therapy) should be considered as the treatment of choice for chronic ulcers owing to its significant advantages in the time to complete healing and wound bed preparation, time compared with conventional wound care.  

In 2000, the FDA approved that wound VAC helps the wounds heal faster and reduce the incidence of infections. In situation where a wound VAC is used, patients tend to have enhanced granulation tissue formation, decreased bacteria and increase in cutaneous perfusion and oxygen tension compared with others where this procedure was not used.


What is a wound VAC and how does it work:

A wound VAC is a machine used to treat advanced bed sore and other chronic wounds. A wound VAC uses a pump to remove excess fluid from bed sore or other wounds that are difficult to heal on their own. An airtight, vacuum chamber is created by a polyurethane material packed into the wound.

A pump is then attached to this area to draw moisture from the wound itself. The pump acts as a vacuum to draw the excess fluids from wound and collect them into a chamber.

VAC (Vacuum Assisted wound Closure) Therapy (also know as Negative Pressure wound Therapy) is a fairly new technique that doctors use to speed up healing in deep wounds.
