NCT ID NCT07431554
First seen Feb 28, 2026 · Last updated May 23, 2026 · Updated 15 times
Summary
This study looks at how the right side of the heart handles low oxygen levels, like at high altitudes, in people who have previously experienced HAPE (fluid in the lungs at altitude). Researchers will simulate altitudes of 2,500 and 4,000 meters using special gas mixtures. 18 adults aged 18-80 with past HAPE will be tested at rest and during light exercise. The goal is to better understand heart strain and help guide future care for these patients.
