Measurement of Cardiopulmonary Variables in a Large Group of Healthy Subjects with Acute Exposure to High Altitude

What this Trial Is About

This research aims to study the effects of acute exposure to high altitude on the heart and lungs in a large group of healthy adults. As altitude rises, oxygen levels decrease, causing the body to work harder to maintain oxygen supply. This can lead to significant changes in heart rate, blood pressure, and oxygen usage, which may pose risks especially for those with existing heart or lung conditions. The study seeks to understand these changes by collecting data from many individuals who rapidly reach high altitude using a cable car. Participants will be assessed at two key locations: the starting point at 1,300 meters and the high altitude point at 3,466 meters on Mont Blanc, accessible by a 20-minute cable car ride. Measurements will be taken using an automated system that records oxygen saturation, heart rate, blood pressure, height, weight, and body mass index. Participants complete a self-reported heart health questionnaire before measurements. Some participants will have data collected at both locations to evaluate changes due to altitude. During the study, participants will undergo quick biometric recordings guided by the system, which provides instructions and prints a summary of results. Data will be anonymized to protect privacy. Researchers will analyze relationships between oxygen levels at high altitude and factors like age, sex, heart rate, blood pressure, and body mass index. The study will also examine how these measurements change immediately after altitude exposure. Participation involves a single visit, and all data collection is non-invasive and automated.
