Perfusion is the process of delivery of blood to a capillary bed in the biological tissue. Tests of adequate perfusion are a part of the patient assessment process performed by medical or emergency personnel. The most common methods include evaluating skin color, temperature, condition and capillary refill. Perfusion can be of two types over perfusion and under perfusion. Types of perfusion is classified according to the average level of perfusion across all tissues in an individual body, Tissues like the heart are considered overperfused and receive more blood than would be expected to meet the metabolic needs of the tissue.
