    What is NPWT?

    NPWT (Negative Pressure Wound Therapy) applies a localized vacuum to help the healing of the wound while stimulating granulation tissue formation and removing exudate.

    Mechanism of NPWT

    There are five main mechanisms by which the application of negative pressure to a wound may aid in the healing process:
    Wound retraction
    Stimulation of granulation tissue formation
    Continuous removal of exudate
    Continuous wound cleansing
    Reduction of interstitial edema
