Perfúzió
Perfúzió, in medical terminology, refers to the passage of fluid through a network of vessels and tissues, delivering oxygen and nutrients and removing waste products. In humans it typically denotes tissue perfúzió—the distribution of blood flow to a given region. Perfúzió can be systemic, reflecting overall cardiac output, or regional, reflecting microvascular flow to organs or tissues. Artificial perfúzió refers to the use of pumps and perfusion solutions to sustain tissue viability during surgery, transplantation, or organ preservation, such as cardiopulmonary bypass or ex vivo organ perfúzió.
Perfúzió depends on perfúziós nyomás (perfusion pressure), vascular resistance, capillary permeability, and the functional state of
Assessment of perfúzió uses imaging and physiological surrogates: CT perfúzió, MR perfúzió, Doppler ultrasound, laser Doppler,
Clinical relevance: inadequate perfúzió contributes to organ dysfunction in critical illness; adequate perfúzió is essential for
Etymology: from Latin perfundere, meaning “to pour through.”
