Participate in an Immersion Pulmonary Edema Research Study?


DURING A TRIATHLON HAVE YOU EXPERIENCED SYMPTOMS OF SWIMMING-INDUCED PULMONARY EDEMA (SIPE)? Have you become short of breath, coughed up pink sputum or been taken to a hospital for treatment of pulmonary edema during or after a triathlon?

  • Doctors at the Duke University Center for Hyperbaric Medicine and Environmental Physiology are performing a research study to determine the cause of SIPE. Triathletes who have experienced SIPE are needed to determine the effect of exercise while immersed to the neck in water on cardiac (heart) function.
  • Subjects will be instrumented with an intravenous catheter and have their heart and lungs studied with echocardiography, chest x-ray, and magnetic resonance imaging.
  • Prior to the study, subjects must come to the laboratory (about 1 hour) for a physical exam, pregnancy test (if needed) and orientation for the following experimental day for 4-5 hours.
  • Subjects will be paid $150 for completion of the entire study and reimbursed for travel.
  • Subjects must be 18-55 years of age, physically fit (be able to exercise constantly for 40 minutes), and have no physical impairment that would prevent them from participation.
