What is Negative Pressure Wound Therapy?

Negative Pressure Wound Therapy (NPWT), also known as wound vac therapy, involves placing a sealed dressing over the wound and applying controlled suction through a vacuum device.

Why it works

The negative pressure draws out excess fluid, reduces swelling, improves blood flow, and helps close the wound. It also keeps the wound environment clean and promotes the growth of healthy tissue.

What should I expect during a NPWT appointment?

A soft foam or gauze dressing is placed into the wound and sealed with a special adhesive drape. A small tube connects the dressing to a vacuum pump that gently applies suction. You’ll typically wear the device continuously between dressing changes, which are done every few days.
