HYPOXIA

This early-phase study tests whether taking iron supplements for 30 days can improve exercise performance in low-oxygen conditions. Five healthy adults will take ferrous sulfate pills daily and then exercise on a stationary bike. The goal is to see if iron helps the heart and lun…

This study looks at whether placing children in a specific position when their breathing tube is removed after sleep apnea surgery can reduce the risk of dangerously low oxygen levels. About 262 children aged 2-10 will take part. The goal is to find a simple, no-cost way to make …

This study will look at how healthy people's bodies respond to exercise while breathing air with less oxygen, similar to being at high altitude. Researchers will measure things like muscle oxygen levels, heart rate, and breathing in 305 volunteers. The goal is to better understan…

This study looks at whether being at a moderate altitude (like 4,000 meters) can hurt your ability to remember to do things later, called prospective memory. Fifty healthy adults will take memory tests while breathing low-oxygen air or normal air in a chamber. Researchers also wa…

This study will test a new noninvasive device that measures oxygen and hemoglobin levels in 7 healthy adults. Participants will be exposed to controlled low oxygen and blood dilution to see how well the device works compared to standard blood tests. The goal is to improve monitor…

This study will test how changes in oxygen levels affect the heart's electrical signals in 70 people, some with oxygen dependence and some healthy. Participants will receive increasing amounts of oxygen at night while their heart activity is monitored. The goal is to better under…
