The extent of the injury is dependent upon temperature and duration of exposure, as well as the vascular supply and the thickness of the injured skin. At the center of the exposure there is an irreversible tissue necrosis. Surrounding the area of central necrosis is a zone of ischemia in which there is a reduction in dermal microcirculation. This ischemic zone may progress to full necrosis unless the ischemia is reversed. At the periphery of the burn is a third zone of hyperemia characterized by a reversible increase in blood flow.
