An uncommon cause of hypoxemia： platypnea-orthodeoxia syndrome

Platypnea-onhodeoxia syndrome （POS） describes a clinical entity of arterial hypoxemia in the upright position associated with dyspnoea, which is relieved by recumbency. The syndrome is caused by an intracardiac or intrapulmonary shunt, or ventilation-perfusion mismatching. We describe here the first...

Description
Summary:Platypnea-onhodeoxia syndrome （POS） describes a clinical entity of arterial hypoxemia in the upright position associated with dyspnoea, which is relieved by recumbency. The syndrome is caused by an intracardiac or intrapulmonary shunt, or ventilation-perfusion mismatching. We describe here the first case of resolving/relapsing POS induced by intracardiac right-to-left shunting that was partly dependent on volume overload.
