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.
