HYPOXIA

This study planned to compare a new type of airway device with a standard one to see if it could prevent dangerously low oxygen levels during anesthesia. It was designed for adults at high risk, such as those with obesity or sleep apnea. However, the study was withdrawn before an…

This study checks how accurately pulse oximeters—devices that shine light through skin to measure blood oxygen—work in healthy adults aged 18 to 50. Participants will have their oxygen levels lowered in a controlled way while the device readings are compared to actual blood sampl…

This study aimed to compare a new oxygen mask (Oxy2mask) with an older version (Oxymask) to see if it works as well, better, or worse. Researchers planned to measure the oxygen flow needed to keep oxygen levels stable in adults. However, the study was withdrawn before any partici…

This study checks how accurately pulse oximeters (devices that measure blood oxygen through the skin) work when oxygen levels are very low. Twelve healthy adults will have their oxygen levels carefully lowered while the device readings are compared to blood samples. The goal is t…

This study follows 30 lung transplant recipients and healthy volunteers as they prepare for and climb Mount Aconcagua (6,971 meters). Participants first use a home hypoxic tent for 8 weeks to condition their bodies, then attempt the summit with medical monitoring. The goal is to …

This study tests whether virtual reality (VR) can train new doctors as well as high-fidelity simulation (using lifelike mannequins) for handling emergencies like severe allergic reactions and low oxygen levels. About 124 medical interns will be randomly assigned to one training m…

This study tests three new pulse oximeters (devices that measure oxygen levels) in 936 children under 2 years old with pneumonia in Cape Town, South Africa. The goal is to see if these devices help healthcare workers correctly identify low oxygen levels and refer children for pro…

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

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…
