Testing inhaled gas therapy for high-altitude lung swelling

This study is testing a new treatment called inhaled nitric oxide (iNO) for a serious condition called high-altitude pulmonary edema (HAPE), which causes fluid to build up in the lungs when people are exposed to high altitudes. The medication is delivered as a gas through a compact, portable device that creates it on-the-spot—no heavy oxygen cylinders needed. Researchers want to see if this treatment helps people breathe better and recover faster compared to standard care alone.

High-altitude pulmonary edema is a dangerous condition that can develop quickly in people exposed to high elevations, and current treatments don't always work fast enough. This trial is testing whether adding this medication can improve oxygen levels in the blood and reduce pressure in the lungs more effectively than traditional medications alone.
