Tissue perfusion is the amount of blood that the tissues receive during circulation. When a person has decreased tissue perfusion, the tissues are receiving inadequate blood supply.
Blood flow and tissue perfusion are NOT the same thing. An increase in blood flow does not always mean that there is a parallel increase in tissue perfusion. While blood flow is generally understood as an increase in the total amount of blood flowing into an anatomic structure or region, tissue perfusion is the amount of blood that actually flow through the capillaries of the vascular bed of that structure or region. The important thing to remember is that nutrients and oxygen are delivered to the cells via the capillaries.
