=Background=
* Negative Pressure Wound Therapy (NPWT), also known as a wound vac, is a technique for treating acute and chronic wounds by using a sealed wound dressing attached to a vacuum pump.
* The vacuum creates a negative pressure gradient that draws out fluid and increases blood flow to the area. 
* Often applied to wounds that are expected to heal poorly, such as diabetic foot ulcers, pressure ulcers, or very large tissue defects.
