Hyperaemiaorhyperemiais the increase of blood flow to different tissues in the body. It can have medical implications, but is also a regulatory response, allowing change in blood supply to different tissues throughvasodilation. Clinically, hyperaemia in tissues manifest aserythema, because of the engorgement of vessels with oxygenated blood.[1]Hyperaemia can also occur due to a fall in atmospheric pressure outside the body.
