A pulmonary shunt often occurs when the alveoli fill with fluid, causing parts of the lung to be unventilated although they are still perfused. Intrapulmonary shunting is the main cause of hypoxemia (inadequate blood oxygen) in pulmonary edema and conditions such as pneumonia in which the lungs become … See more 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.

WebApr 12, 2024 · Thus, alveolar dead space representing areas of adequate ventilation, but impaired perfusion is in direct contrast to areas of the lung that are poorly ventilated, with normal perfusion (low V/Q, leading to shunting). In most parenchymal disease processes, the mechanism for hypercapnia is an increase in the alveolar dead space. WebDifferent kinds of intrapulmonary shunts can occur, with the venous admixture being the end result of these shunts. ...
