Breathing device for preventing altitude sickness

This trial tests how acetazolamide affects your body's fluid levels at high altitude. It might help understand if the drug can prevent altitude sickness.

This trial investigates whether a medication usually used for migraines (fremanezumab) can help prevent acute mountain sickness in healthy adults who travel to high altitudes. You would receive an injection and be monitored for symptoms.

This study tests whether spending time at a moderate altitude (like a mountain resort) can help people with COPD breathe easier. It measures how open your airways are using a special test while you do a rehabilitation program.

This study tests personalized health check-up programs for people who live in low-altitude areas and plan to move to a high-altitude plateau. It aims to find the best ways to keep you healthy during and after the move.

This trial tests whether a mask that helps you breathe out (positive expiratory pressure) combined with a cough-assist machine (in-exsufflator) improves breathing and coughing in people with ALS who have bulbar symptoms like trouble speaking, swallowing, or drooling.

This study is for people living at high altitudes (above 2,500 meters) to understand how the pressure in the arteries of the lungs changes over time and how it affects health. It may help doctors predict and manage heart and lung problems that can occur in high-altitude residents.
