Reactive hyperemia vs active hyperemia

WebThe presence of an increased amount of blood in a body part or an organ leading to congestion or engorgement of blood vessels. Hyperemia can be due to increase of blood flow into the area (active or arterial), or due to obstruction of outflow of blood from the area (passive or venous). Year introduced: 1966 PubMed search builder options WebReactive hyperemia is caused by a blocked blood supply, while active hyperemia is caused by an increase in metabolic activity.

WebHyperemia is an active engorgement of vascular beds with a normal or decreased outflow of blood. It occurs because of increased metabolic activity of tissue that results in localized increased concentrations of CO2, acid, and other metabolites. These cause a local stimulus for vasodilation and increased flow (hyperemia). WebNov 5, 2014 · in two forms: active and reactive. Active hyperemia is related to the increase of blood flow to a tissue according to its metabolic activity. This occurs, for example, during physical exercise, when the metabolic activity of the exercised muscles increases and local metabolites induce vasodilation and in-crease local blood flow.
