A pulmonary shunt is the passage of deoxygenated blood from the right side of the heart to the left without participation in gas exchange in the pulmonary capillaries. It is a pathological condition that results when the alveoli of parts of the lungs are perfused with blood as normal, but ventilation (the supply of air) fails to supply the perfused region. In other words, the ventilation/perfusion ratio (the ratio of air reaching the alveoli to blood perfusing them) of those areas is zero. irma seth violonisteWebApr 1, 2011 · True shunting, defined as venous blood mixing directly with end-capillary blood at the arterial side of the circulation, is not a usual cause of hypoxaemia in COPD 1, 2.
