Key result
A history of swimming-induced pulmonary edema was not associated with differences in pulmonary function, exercise capacity, or pulmonary arterial pressure response to hypoxemia in dry conditions.
Why the study?
Does a history of swimming-induced pulmonary edema (SIPE) result in abnormal cardiopulmonary function or pulmonary arterial pressure response to hypoxemia in US Navy Special Warfare members?
Case-Control
No
Does a history of swimming-induced pulmonary edema (SIPE) result in abnormal cardiopulmonary function or pulmonary arterial pressure response to hypoxemia in US Navy Special Warfare members?
Patients with a history of swimming-induced pulmonary edema do not exhibit abnormal baseline cardiopulmonary function or abnormal pulmonary arterial pressure response to hypoxemia when tested in dry conditions.
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.

Ludwig et al. (2006) conducted a case-control in Swimming-induced pulmonary edema (SIPE). History of swimming-induced pulmonary edema (SIPE) vs. Controls was evaluated on Pulmonary function testing, carbon monoxide diffusing capacity, maximal oxygen consumption, and pulmonary arterial pressure response to hypoxemia. A history of swimming-induced pulmonary edema was not associated with differences in pulmonary function, exercise capacity, or pulmonary arterial pressure response to hypoxemia in dry conditions.
