What’s the difference between V.A.C. Therapy and other NPWT devices?
There is an important difference between V.A.C. Therapy and other Negative Pressure Wound Therapy devices. V.A.C. Therapy has been proved to improve your wound healing outcomes20,5,1,3. Only the integrated V.A.C. Therapy System uses V.A.C. GranuFoam™ Dressings in the wound–other NPWT devices typically use gauze dressings. Under negative pressure, the hydrophobic, reticulated, open pore structure of V.A.C. GranuFoam Dressings creates an environment that promotes faster20 and more effective5 wound healing at the cellular level compared to gauze11,13. When negative pressure is applied to the wound bed through the V.A.C. GranuFoam Dressing, mechanical forces stretch cells as tissue is pulled into the open pores of the dressing. The stretching stimulates cellular proliferation, which results in the formation of granulation tissue2,12,13. Because gauze does not have the open pore structure of V.A.C. GranuFoam Dressings, gauze has not been shown in laboratory testing to increase cellular acti
