does not rule out an increased difference in alveolar-arterial oxygen tension caused by physiologic shunting (failure of all the pulmonary capillary blood to be equally exposed to oxygen).

Prolonged cardiopulmonary support over weeks to months has been achieved using the pulmonary artery trunk and the left atrium LAD support, allowing extubation and a degree of physical ...
