There is only one
3M™ V.A.C.® Therapy,
the original NPWT.
A world leader in negative pressure wound therapy - driven by science.
3M™ V.A.C.® Therapy
V.A.C.® Therapy repeatedly sets the standard for negative pressure wound therapy (NPWT). Since it has been used to treat more than 10 million wounds1 worldwide, there is reliable clinical evidence that associates V.A.C.® Therapy with reduced risk of readmission and reduced need of reoperation2 — ultimately reducing hospitalisation time and the risk of complications.2,3 Not all NPWT is the same, and choosing V.A.C.® Therapy can help improve patient care and your bottom line.
-
50% less time for acute wounds and 67% less for chronic wounds
When V.A.C.® Therapy was initiated early in the wound care clinic treatment time period compared to late initiation, the days to reach significant closure (75% wound surface area reduction) were significantly decreased.4 Early initiation* of V.A.C.® Therapy has been shown to reduce 50% time for acute wounds and 65% time for chronic wounds.
Based on a retrospective analysis conducted on a national insurance provider’s medical claims data, which examined 6,181 acute and 1,480 chronic wound patients that received NPWT from January 1, 2009 to June 30, 2011.
*Defined as treatment within the first 7 days for acute wounds and 30 days for chronic wounds from the first wound treatment date.
-
21%–34% lower total costs across wound types at 12 months
In a retrospective analysis of U.S. insurance claims in the outpatient setting, patients who received V.A.C.® Therapy had lower total and wound-related treatment costs than patients who received alternative negative pressure wound therapy, in all wound types across all time periods studied.3
-
Backed by clinical evidence
V.A.C.® Therapy continues to have the largest body of NPWT evidence in the world with 2,000+ peer-reviewed publications and more than 75% of published NPWT clinical evidence is based on V.A.C.® Therapy.6
These studies have demonstrated several benefits of NPWT, as well as the effectiveness of V.A.C.® Therapy in helping to manage diabetic foot wounds, chronic wounds (e.g., pressure ulcers and lower extremity ulcers), and a variety of acute wounds.

How does 3M™ V.A.C.® Therapy work?
See the 3M™ V.A.C.® Therapy Mechanism of Action
V.A.C.® Therapy is the original, foundational NPWT and one of the world leaders in NPWT. It promotes an environment for wound healing by protecting the wound from external contamination, providing a moist wound environment, and promoting the formation of granulation tissue.6
The combination of 3M’s proprietary foam, drape, multi-lumen tubing, and advanced algorithms enable you to provide a uniform negative pressure to the wound surface. This consistent negative pressure helps draw wound edges together, allows for the removal of exudate and infectious material, and stimulates the growth of tissue so the wound can heal.
-
1) Draws wound edges together
The application of uniform negative pressure induces a physical response — macrostrain — that can be seen immediately as the wound edges are drawn together, allowing for optimal contact between the wound bed and the dressing.7
-
2) Removes exudate and infectious material
Macrostrain facilitates removal of wound exudate which may contain inhibitors of wound healing.6
-
3) Reduces Oedema and promotes perfusion
Removal of wound fluids assists in the reduction of oedema, which facilitates the flow of blood into the wound bed, providing the oxygen and nutrients that are needed for wound healing.6
-
4) Promotes granulation tissue formation
In vitro/in vivo studies show that foam contact with tissue creates micro-deformation that leads to cell stretch.7 Cell stretch under negative pressure stimulates cellular activity that results in granulation tissue formation.8
Over subsequent dressing changes, the granulation tissue fills the wound bed, further reducing the volume, and preparing it for final closure.
Learn what sets V.A.C.® Therapy apart
At 3M we focus on providing better healthcare solutions through science — designing around patients and those who care for them.
As a result of this commitment, bench testing in a simulated wound model with V.A.C.® Therapy versus other leading NPWT systems showed:
- 90% more accurate delivery of negative pressure9
- Removal of fluid 98% faster10
- Removal of the same volume of fluid in 15 minutes that required 24 hours in other systems10

This is the first-ever acrylic and silicone hybrid drape for use with V.A.C.® Therapy. The forgiving silicone intelligently contours to the patient's body and allows for drape repositioning upon initial placement, while the high-tack acrylic layer provides a tight seal.
Evidence shows it increases patient comfort: 100% (n=17) of patients in a customer preference test agreed that V.A.C. Dermatac Drape was painless upon removal.11
-
V.A.C.® Therapy is the only NPWT that features proprietary SensaT.R.A.C. Technology.
In conjunction with specialised software, V.A.C.® Therapy detects blockages, senses pressure changes, and notifies you with alarms when target pressure is not achieved. -
3M™ V.A.C.® Granufoam™ Dressings
When granulation tissue formation is a key part of your patient’s healing, choose V.A.C.® Granufoam Dressings.
These wound dressings come in multiple shapes and sizes to accommodate diverse wounds, and you can easily trim them to fit the contours of deep or irregularly shaped wounds.
For patients with multiple wounds, you can customisable the dressings for bridging techniques.

Case study Excerpt: V.A.C.® Therapy with 3M™ V.A.C.® Granufoam Dressing and V.A.C. Dermatac Drape
A 61-year-old female underwent a complex right forefoot reconstruction due to a deformity. Both wound sites, the dorsal and medial incisions, developed a dermal dehiscence and were managed with serial debridements and 3M™ Silvercel™ Antimicrobial Alginate Dressing. The dorsal incision healed, but the medial incision demarcated and increased in depth.
The wound was mostly fibrinous with a small area of exposed bone. V.A.C.® Therapy was applied at -125mmHg, using a foam dressing and Dermatac Drape. After five days, the wound was mostly granular, with a small area of exposed bone. After the dressing change, V.A.C.® Therapy was discontinued due to the small size of the wound.

Real world data demonstrated V.A.C.® Therapy delivers lower total cost to treat compared to other NPWT providers studied.3
In a retrospective analysis of 6,736 U.S. insurance claims in the outpatient setting, patients who received V.A.C.® Therapy had lower total and wound-related treatment costs than patients who received competitor NPWT, in all wound types across all time periods studied.
V.A.C.® Therapy patients had 32%–37% lower total and wound related costs across time periods and lower total out-of-pocket costs. Lower total costs to treat V.A.C.® Therapy patients driven by lower home health agency, skilled nursing facility, NPWT, and other expenses. NPWT charges represented only 3% of the total cost to treat.*

The evidence behind V.A.C.® Therapy
In a retrospective analysis of 3,604 patients, when V.A.C.® Therapy was initiated early in acute (within the first 7 days) and chronic wounds (within the first 30 days) of varying size, the treatment time compared to late initiation (after the early time periods).
Early initiation of NPWT shows benefits across many care settings.12-14
-
What would 178 fewer days mean to your patients?
The median days to reach significant closure (75% wound surface area reduction) were 41.4 fewer days for acute wounds and 178 fewer days for chronic wounds compared to late initiation of NPWT.4
Additionally, the early group was twice as likely to reach 75% surface area reduction as the late group for both acute and chronic wounds.
-
Early initiation* of NPWT has been shown to reduce length of stay
- Reduced inpatient days in acute and intensive care unit by at least 50%15
- Reduced inpatient days in long term acute care by 30%14
- Reduced homecare length of stay by 34% for surgical wounds13
- Reduced homecare length of stay by 49% for pressure injuries13
*Early: Acute wounds defined as NPWT initiated within the first 7 days. Chronic wounds are defined as NPWT initiated within the first 30 days. Late: NPWT initiation occurred after these periods.
