RESUMEN
OBJECTIVE: This study aimed to compare cardiopulmonary function in patients with a history of swimming-induced pulmonary edema (SIPE) with controls by measuring pulmonary function tests, oxygen consumption with exercise, and the pulmonary arterial pressure response to hypoxemia. DESIGN: Case control study. SETTING: Tertiary Military Medical Center. PATIENTS: US Navy Special Warfare members who had previously suffered SIPE. INTERVENTIONS: Measurement of pulmonary function tests, cardiopulmonary exercise test, pulmonary artery pressure by echocardiography at rest on room air and with hypoxia. MAIN OUTCOME MEASUREMENTS: Pulmonary function testing, carbon monoxide diffusing capacity, maximal oxygen consumption, and pulmonary arterial pressure response to hypoxemia. RESULTS: Subjects who previously had SIPE did not demonstrate differences in pulmonary function tests, carbon monoxide diffusing capacity, maximal oxygen consumption, or pulmonary arterial pressure response to hypoxemia. CONCLUSIONS: Subjects with a history of SIPE do not have abnormal pulmonary function tests, abnormal exercise capacity, or abnormal pulmonary arterial pressure response to hypoxemia when tested in dry conditions.
