Lung function at sea level vs. high altitude in pulmonary hypertension
Part of Lungs & breathing clinical trials.
This study compares how well your lungs work when you are at high altitude (your home) versus when you visit sea level. It aims to understand how altitude affects people with pulmonary arterial hypertension, which is high blood pressure in the lungs.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are between 18 and 80 years old.
- You have been diagnosed with pulmonary arterial hypertension (PAH) and are stable on your current treatment.
- You live permanently at an altitude above 2600 meters (about 8500 feet).
- You have not traveled to lower altitudes (below 2000 meters) in the past 4 weeks.
- You do not have severe lung disease, severe smoking habits, or other serious heart, kidney, liver, or blood conditions.
- You are willing to give written consent to participate.

This study compares how the heart and lungs respond at high altitude versus sea level in people with pulmonary arterial hypertension (PAH), a type of high blood pressure in the lungs. It may help doctors understand if living at high altitude affects symptoms and treatment.
This study looks at how the heart and lungs respond when people with pulmonary hypertension travel from low to high altitude. It may help doctors understand how to better care for patients living at high altitudes.
This study looks at how your heart rate changes when you travel from high altitude (about 2850 meters) down to sea level and back up again. It may help doctors understand if such travel is safe for people with pulmonary hypertension.
This study compares sleep quality and breathing patterns in people with pulmonary arterial hypertension (PAH) who live at high altitude versus those at sea level. It aims to understand how altitude affects sleep in PAH, which could help improve care for patients living in high-altitude areas.
This study measures how well your lungs work at sea level compared to high altitude in healthy people. By joining, you'll help researchers understand how the body responds to different oxygen levels.
This study compares how far you can walk in six minutes at sea level versus at high altitude (where you live) after returning to high altitude. The goal is to see if being at high altitude affects your exercise capacity, which may help guide future care.
