What it means
Also called negative pressure wound therapy. Foam or gauze is placed in the wound and sealed with a clear film, and a tube connects it to a small pump that applies steady gentle suction. This removes drainage, reduces swelling, pulls the edges together and helps new tissue grow. It is used for large, slow-healing, surgical and pressure wounds.
For the nurse
Keep the seal airtight and answer leak alarms. Do not leave the dressing without suction for longer than the facility allows. Note the amount and color of drainage in the canister, and stop the pump and report bright red blood.
