Negative Pressure Wound Therapy (NPWT) is an advanced adjunct therapy that uses controlled sub-atmospheric pressure to support wound healing. It typically involves a medical-grade foam (or gauze) dressing, a transparent sealing drape, and a vacuum pump that maintains an airtight environment over the wound.

NPWT is often considered for large, deep, or heavily exudative wounds—for example, Stage 4 pressure injuries, post-surgical wounds with delayed healing, and selected post-grafting wounds.

When NPWT may not be suitable: In general, NPWT is not recommended for wounds with malignancy in the wound bed, untreated osteomyelitis, or exposed major blood vessels, unless specifically assessed and managed by the treating team.

How NPWT Supports Healing: 5 Key Mechanisms

1.     Exudate management (fluid removal): Continuous suction helps remove excess wound fluid and reduces bioburden in the wound environment, supporting infection risk control.

2.     Edema reduction (improving microcirculation): By drawing off interstitial fluid, NPWT can reduce tissue swelling and improve local blood flow and oxygen delivery.

3.     Granulation tissue formation (mechanical stimulation): The negative pressure provides gentle mechanical forces that stimulate cellular activity and promote healthy granulation tissue to fill wound cavities.

4.     Wound contraction: The therapy can help draw wound edges inward over time, supporting gradual reduction in wound size.

5.     Less frequent dressing disturbance: Dressings are commonly changed every 2–3 days (depending on wound status), which can reduce disruption to fragile new tissue compared with very frequent dressing changes.

Modern Convenience: Professional Care at Home

NPWT technology has become more portable. Many systems are now lightweight and battery-powered, making it feasible for selected patients to continue treatment at home with professional support and monitoring.
