Educational Pearls:

  • SIPE or SWIPE stands for Swimming Induced Pulmonary Edema and usually occurs in young people without previous pulmonary problems or CHF.
  • Happens more often in cold water, and could be a combination of increased cardiac output, increased permeability of capillary bed and increased pressure in capillary bed.
  • Presents either during the swim or after the swim – most patients will be hypoxic and have to be pulled out of the water. Patients will have rales and can have hemoptysis.
  • Treatment is symptomatic, most episodes resolve in 12-24 hours, but patients have an increased risk of recurrence in the future.
  • Another swimming related issue is shallow water syncope – which happens in people who are extremely good swimmers.
  • Generally happens when the patient is trying to hold their breath underwater for a long period of time.
  • Hypercarbia is what causes the urge to breath, and good swimmers can resist this urge. Up to the point that they suddenly become hypoxic, lose consciousness, and may drown.
