Swimming-induced Pulmonary Edema (SIPE) is a condition caused by excess fluid in the lungs. If you have ever experienced shortness of breath, coughing up pink mucus, and/or crackling feelings deep in the chest associated with breathing, you may have experienced SIPE. It can affect people of all ages in any fitness level, even those who are considered generally healthy and occurs more frequently in adults who subject themselves to heavy exertion during swimming, diving, and similar water sports.

Researchers seek to determine whether Viagra, can help to prevent swimming induced Pulmonary Edema. Additional details can be found here
