Machine perfusion (MP) is an artificial perfusion technique often used for organ preservation to help facilitate organ transplantation.MP works by continuously pumping a specialized solution through donor organs, mimicking the body's natural blood flow while actively controlling temperature, oxygen levels, chemical composition, and mechanical stress within the organ.
A ventilation/perfusion lung scan, also called a V/Q lung scan, or ventilation/perfusion scintigraphy, is a type of medical imaging using scintigraphy and medical isotopes to evaluate the circulation of air and blood within a patient's lungs, [1] [2] in order to determine the ventilation/perfusion ratio.
Ex vivo lung perfusion, EVLP, is a form of machine perfusion aimed at sustaining the active aerobic cellular metabolism of donor lungs outside the donor's body prior to lung transplantation. This medical preservation technique typically occurs within a specialised machine engineered to mimic the conditions of the natural circulatory system .
Ventilation–perfusion coupling is the relationship between ventilation and perfusion in the respiratory and cardiovascular systems. [1] Ventilation is the movement of air in and out of the lungs during breathing. [2] Perfusion is the process of pulmonary blood circulation, which reoxygenates blood, allowing it to transport oxygen to body tissues.
Extracorporeal membrane oxygenation (ECMO), is a form of extracorporeal life support, providing prolonged cardiac and respiratory support to persons whose heart and lungs are unable to provide an adequate amount of oxygen, gas exchange or blood supply to sustain life.
Perfusion is the passage of fluid through the lymphatic system or blood vessels to an organ or a tissue. [1] The practice of perfusion scanning is the process by which this perfusion can be observed, recorded and quantified. The term perfusion scanning encompasses a wide range of medical imaging modalities. [2]

A perfusionist in front of a heart–lung machine (upper right) early in a coronary artery bypass surgery. A cardiovascular perfusionist, clinical perfusionist or perfusiologist, and occasionally a cardiopulmonary bypass doctor [1] [2] or clinical perfusion scientist, [3] is a healthcare professional who operates the cardiopulmonary bypass machine (heart–lung machine) during cardiac surgery ...
