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.
