Swimming-Induced Pulmonary Edema: Evaluation, Diagnosis, and Treatment

Swimming-induced pulmonary edema (SIPE) is a rare but life-threatening acute illness that can occur in otherwise healthy athletes and individuals. Also known as immersion pulmonary edema, SIPE presents in swimmers, snorkelers, and SCUBA divers. It occurs in persons under heavy exertion in cold water temperatures, leading to coughing, shortness of breath, and sometimes blood-tinged sputum. Under these conditions, there is increased pulmonary vascular pressure, which may ultimately lead to pulmonary edema. This article synthesizes the latest data on the prevalence, pathophysiology, etiology, risks, short- and long-term complications, and the efficacy of supportive medical treatment interventions.
