Negative Pressure Wound Therapy
(NPWT or Wound VAC Therapy)

This handout explains what Negative Pressure Wound Therapy is and how it may help
you. This treatment uses negative pressure (or suction), to help wounds heal.

ξ Increases blood flow to wound.
ξ Provides a moist wound healing environment.
ξ Draws wound edges together.
ξ Removes excess fluid and infectious materials.
ξ Reduces wound odor.
ξ Reduces need for frequent dressing changes.

How it works
ξ A special foam dressing is placed in the wound.
ξ A clear adhesive dressing seals in the foam dressing to create an airtight seal.
ξ Tubing is connected to the dressing, and to the NPWT machine.
ξ Therapy is started to preset negative pressure (suction) settings.
ξ Wound drainage collects in a disposable canister.
ξ The NPWT machine can be disconnected from outlet for short periods of time
(i.e. a walk in the hall, gone for a test). To keep the battery charged, the machine
should be plugged in as much as possible.
