New oxygen method may speed recovery from High-Altitude lung condition

This study tests if a special high-flow oxygen mask works better than standard oxygen for people with high-altitude pulmonary edema (fluid in the lungs from climbing too high too fast). About 200 adults who develop symptoms within 7 days of reaching high altitude will be randomly assigned to one of two oxygen treatments. The main goal is to see which method helps patients stop needing extra oxygen sooner.
