Risk of high-altitude travel in a patient with Eisenmenger's syndrome
Abstract:
We used ear oximetry in combination with maneuvers of hypoxic breathing, exercise, and hyperoxic breathing to assess the cardiopulmonary function of a patient with Eisenmenger's syndrome. The results showed that mild alveolar hypoxia decreased O2 SAT moderately, that exercise alone decreased O2 SAT markedly, and that oxygenation was improved with increased inspired oxygen fraction.
