Blood Flow Responses in the Peristernal Thoracic Wall During Vacuum-Assisted Closure Therapy

Vacuum-assisted closure therapy induces a change in microvascular blood flow that is dependent on the pressure applied, the distance from the wound edge, and the tissue type. It may be beneficial to tailor the negative pressure used for vacuum-assisted closure therapy according to the wound tissue composition. Wound fluid partial pressure of oxygen and lactate levels increased during vacuum-assisted closure therapy. This combination is known to promote wound healing.
