HYPOXIA

This study is testing how well a new type of pulse oximeter works. Pulse oximeters are the small devices that clip on your finger to measure blood oxygen levels without a needle. Researchers are checking the device's accuracy by having healthy volunteers breathe different air mix…

This study aims to check how accurately pulse oximeters measure blood oxygen levels when they are intentionally lowered. Healthy adult volunteers will have their oxygen levels carefully reduced while researchers compare the pulse oximeter readings to direct blood measurements. Th…

This study is testing whether existing, approved drugs can help red blood cells work better under extreme stress from cold temperatures and low oxygen, like those found at high altitudes. Researchers will take blood samples from 50 healthy adults to see how the drugs affect the c…

This study aims to understand how people who have received a lung transplant adapt to very high altitudes, compared to healthy people. Thirty participants, including lung transplant recipients and healthy volunteers, will undergo home-based altitude training and then attempt to c…

This study aims to create a single, standard test to understand why some physically active people handle exercise in low-oxygen conditions better than others. Researchers will measure factors like breathing, heart rate, and blood chemistry in 50 participants during a stepwise exe…
