How does negative pressure wound therapy work?

The NPWT device works by providing and distributing negative pressure evenly across the wound bed either through the application of an open cell foam or a gauze dressing [7]. Both foam and gauze have been shown to be equally effective at wound contraction and stimulation of blood flow at the wound edge [8].
