Is Negative-Pressure Wound Therapy Right for You?

What Is NPWT?

Negative-Pressure Wound Therapy (also called vacuum-assisted closure or VAC) uses suction to remove fluids, reduce swelling, and help wounds close faster.

How It Works

A foam dressing is placed over the wound, sealed with a bandage, and connected to a small vacuum pump that gently draws out fluids and pulls wound edges together.
