durchblutet

Durchblutet is a German adjective used primarily in physiology and medicine to describe tissue, an organ, or a region of the body that receives an adequate or increased supply of blood. The term literally refers to blood passing through the circulatory system to the tissues, and is commonly used to express that perfusion is sufficient for metabolic needs. It is often contrasted with poor perfusion or ischemia.

Blood flow to tissues is governed by cardiac output, vascular resistance, and the state of the microcirculation, including arterioles and capillaries. Autoregulation adjusts perfusion to metabolic demand, while autonomic input and local mediators such as nitric oxide, adenosine, and temperature influence vasodilation or vasoconstriction. A tissue is considered durchblutet when perfusion meets the requirements of resting and active states, and when the microvascular network can deliver oxygen and nutrients efficiently.

Clinically, the concept is important for organs such as the heart, brain, muscles, kidneys, and skin. Insufficient Durchblutung can lead to ischemia and tissue injury, whereas adequate perfusion supports function and healing. Assessment methods include Doppler ultrasound, magnetic resonance perfusion imaging, and computed tomography perfusion, alongside clinical signs like skin color, temperature, and capillary refill.

In everyday medical terminology, durchblutet is used in phrases such as gut durchblutet (well-perfused). Related terms include Durchblutung (perfusion) and Durchblutungsstörung (perfusion disorder). The word is primarily employed in technical or clinical contexts and conveys the adequacy of blood supply to tissues.
