Blood passing through areas of absolute shunt receives no oxygen (V/Q = 0), therefore, arterial hypoxemia resulting from intrapulmonary shunt is minimally responsive to supplement oxygen. Shunt effect (venous admixture or low V/Q) is the more common clinical scenario in which areas of lung have poor alveolar ventilation compared to the degree of alveolar perfusion ( 0 < V/Q < 1).
