Poor peripheral perfusion
WebPerfusion Pressure. Perfusion pressure is what keeps blood flowing to every part of your body, even those farthest away from your heart. When you don’t have enough perfusion … WebThe peripheral arteries are narrowed and, in some cases, totally obstructed, and they rely on collateral circulation to supply blood to distal areas. If these collaterals are damaged during harvesting, it can jeopardize the circulation and impair wound healing. Smoking. Its association with poor wound healing is due to its association with PVD.
