What causes reactive hyperemia to increase tissue perfusion? local controls hormonal controls respiratory controls urinary controls?

I believe that local controls are what causes reactive hyperemia to increase tissue perfusion. Reactive hyperemia or venous hyperemia is the transient increase in organ blood flow that occurs following a brief period of ischaemia. 
Tissue perfusion is the decrease in oxygen resulting in the failure to nourish the tissues at the capillary level. Local blood flow regulation involves the rapid control of arterial vasomotion based on the metabolic needs of the surrounding tissues and cells.
