نبذة مختصرة
We present the findings in a patient with liver cirrhosis who showed oppositional pulmonary vascular responses to various alveolar oxygen tensions. In this case the pulmonary artery constricted on exposure to hyperoxia and then gradually dilated during progressive hypoxic inhalation. Such a paradoxic response must result in severe arterial hypoxemia because of severe V/Q mismatching.
