HYPOXIA

This study was designed to see if a new type of breathing tube could help prevent dangerously low oxygen levels during anesthesia in people at high risk, such as those with obesity or sleep apnea. It planned to compare the new device with standard tubes in adults having surgery a…

This study tests three new pulse oximeters (devices that measure oxygen levels) in 936 young children with breathing infections in Cape Town, South Africa. The goal is to see if these devices help healthcare workers correctly identify low oxygen and refer children for proper care…

This study compares virtual reality (VR) training with high-fidelity simulation (HFS) for teaching new doctors how to handle emergencies like severe allergic reactions and low oxygen levels. About 124 medical interns will be randomly assigned to either VR or HFS training, then te…

This study aimed to compare a new oxygen mask (Oxy2mask) with an older version (Oxymask) to see if it works as well or better for adult patients with low oxygen levels. Researchers planned to measure the oxygen flow needed to keep patients' oxygen levels stable. However, the stud…

This study looks at whether a drug can improve how red blood cells work in extreme cold or low-oxygen environments, like high altitudes. Researchers will test the drug on blood samples from 50 healthy adults to see if it boosts the cells' energy and antioxidant defenses. The goal…

This study from Mayo Clinic is creating a single, standard test to see how well people handle low oxygen (hypoxia) while exercising. Researchers will measure things like breathing, heart rate, and blood oxygen levels in 50 physically active adults. The goal is to find out why som…

This study follows 30 lung transplant recipients and healthy volunteers as they prepare for and climb Mount Aconcagua, the highest peak in the Americas. Participants first use a special tent at home to get used to lower oxygen levels, then attempt the summit with medical monitori…

This study checks if pulse oximeters (the devices that clip on your finger to measure blood oxygen) are accurate even when oxygen levels drop very low. Twelve healthy volunteers will have their oxygen temporarily lowered while the device readings are compared to blood samples. Th…

This study checks how accurate pulse oximeters are at measuring blood oxygen levels. Healthy volunteers aged 18 to 50 will have their oxygen lowered in a controlled setting while the device readings are compared to actual blood samples. The goal is to improve device accuracy, not…
