Lung transplant patients aim for aconcagua summit in landmark altitude study
NCT ID NCT07479511
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 30 lung transplant recipients and healthy volunteers as they prepare for and climb Mount Aconcagua (6,971 meters). Participants first use a special tent at home for eight weeks to get used to lower oxygen levels. Then, a team monitors their lung function, oxygen levels, and symptoms during the actual climb. The goal is to learn how well transplant lungs adapt to extreme altitude and whether such expeditions are safe.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- intermittent hypoxic conditioning via normobaric hypoxic tent
- What this could lead to
- If successful, this could show that lung transplant recipients can safely adapt to extreme altitudes, potentially improving their physical fitness and quality of life.
- What could go wrong
- This is a small observational study (30 participants) with no control group for the intervention. High-altitude exposure carries risks like acute mountain sickness, and results may not apply to all transplant recipients.
