Reactive Hyperemia. Reactive hyperemia is the transient increase in organ blood flow that occurs following a brief period of ischemia (e.g., arterial occlusion).hen the occlusion is released, blood flow rapidly increases (i.e., hyperemia occurs) that lasts for several minutes. The hyperemia occurs because during the period of occlusion, tissue hypoxia and a build up of vasodilator metabolites (e.g., adenosine) dilate arterioles and decrease vascular resistance.
Blanchable Erythema-Reactive Hyperemia. The picture above demonstrates Blanchable Erythema or Reactive Hyperemia, over a bony prominence, a dangerous sign in tissue that a pressure ulcer is imminent in formation.Reactive hyperemia as its name suggests is a reaction to pressure exerted on the body causing blockage of arteries.As a protective mechanism in the body, blood vessels dilate in the effected area to increase blood flow and deliver oxygen to the tissues.lanchable Erythema-Reactive Hyperemia.
