Platypnea-orthodeoxia has been described in patients with pulmonary shunts, intracardiac shunts, and severe lung disease. We report a case of platypnea-orthodeoxia in a patient with minimal obstructive lung disease and progressive autonomic failure. We have shown our patient's syptoms to be the result of an orthostatic increase in ventilation-perfusion mismatching and to be corrected with fluid challenge.
