The Science
KCI has revolutionized advanced wound care with the development of Negative Pressure Wound Therapy (NPWT). Utilizing multiple mechanisms of action, V.A.C.® Therapy is intended to create an environment that promotes wound healing by secondary or tertiary (delayed primary) intention by preparing the wound bed for closure, reducing edema, promoting granulation tissue formation and perfusion, and by removing exudate and infectious material.How V.A.C.® Therapy Works
V.A.C.® Therapy is the controlled application of sub-atmospheric pressure to a wound using a therapy unit to intermittently or continuously convey negative pressure to a specialized wound dressing to help promote wound healing. The wound dressing is a resilient, open-cell foam surface dressing, such as GranuFoam® and V.A.C.® WhiteFoam, that assists tissue granulation, and is sealed with an adhesive drape that contains the subatmospheric pressure at the wound site. Special SensaT.R.A.C.® technology enhances patient safety by monitoring pressure at the wound site.
The Three Essentials
See how the V.A.C.® Therapy System promotes healing at the cellular level.
1. V.A.C.® GranuFoam® dressings are designed to promote:
Macrostrain
- Contracts under negative pressure, drawing the wound edges together
- Provides direct and complete contact with the wound surface for even pressure and distribution
- Removes exudate and infectious materials-- even during compression-- via a hydrophobic, open-pore foam
Microstrain
- Induces stretch at the cellular level
- Promotes granulation tissue formation through cell migration and proliferation
- Promotes perfusion
2. SensaT.R.A.C® Technology provides:
- Ability to monitor and maintain target pressure
- Sealcheck™ to help identify and repair leaks
- Audible and visual alarms for enhanced patient safety
- Flexible SensaT.R.A.C.® Pad for easy application over body contours
3. The ActiV.A.C.® Therapy Unit provides intermittent and continuous therapy while helping to address patient compliance.
