This study looks at whether placing children in a specific position when their breathing tube is removed after sleep apnea surgery can lower the chance of dangerously low oxygen levels. About 262 children aged 2 to 10 having tonsil or adenoid removal will be randomly assigned to …

This study tests whether taking iron supplements can improve exercise performance in low-oxygen conditions, like at high altitudes. Five healthy adults aged 18-60 will take iron pills and then exercise on a bike to measure their maximum workload and oxygen use. The goal is to see…

This study looks at how the right side of the heart responds to low oxygen, like at high altitudes, in people with asthma. 18 adults with well-controlled asthma will breathe special gas mixtures that mimic altitudes of 2,500 and 4,000 meters. Researchers will measure heart functi…

This study will measure how the body reacts to low oxygen levels and blood thinning in 7 healthy adults. Researchers will compare device readings with lab tests to improve monitoring tools. Participants must be in good health and fluent in English.

This study looks at whether being at a moderate altitude (like 4,000 meters) affects your ability to remember to do things later, called prospective memory. Fifty healthy adults will perform memory tasks in a chamber that mimics high altitude and compare results to normal conditi…

This study looks at how changes in oxygen levels affect the heart's electrical signals in 70 people, both those who need extra oxygen and those who don't. Researchers will measure heart rate variability and other ECG readings to understand the connection. The goal is to learn mor…
