HYPOXIA

This study tests whether virtual reality (VR) can train new doctors as well as high-fidelity mannequins for handling emergencies like severe allergic reactions and low oxygen levels. 124 medical interns will be randomly assigned to either VR or mannequin training, then tested on …

This study is testing two new types of pulse oximeters—simple devices that measure oxygen levels—for babies and toddlers with pneumonia in Cape Town, South Africa. Researchers want to see if these devices help healthcare workers correctly identify children with low oxygen and ref…

This study was designed to see if a new type of airway device can prevent dangerous drops in oxygen levels during anesthesia in patients who are at high risk, such as those with obesity or sleep apnea. Researchers planned to compare the new device with standard ones in adults und…

This study aimed to compare a new oxygen mask (Oxy2mask) with an older version (Oxymask) to see if they work equally well at delivering oxygen. Researchers planned to measure the oxygen flow needed to keep adult patients' oxygen levels stable. However, the study was withdrawn bef…

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 special tent at home for eight weeks to get used to lower oxygen levels. Then, a team monitors their lung function, oxyge…

This study checks how accurately a pulse oximeter (a device that shines light through skin to measure blood oxygen) works during controlled low-oxygen breathing. About 48 healthy volunteers aged 18-50 will breathe a special gas mixture to safely lower their oxygen levels. Researc…

This study tests whether a drug can help red blood cells work better in low-oxygen (hypoxia) and cold (hypothermia) conditions, which are common in high-altitude or military environments. Researchers will measure how the drug affects red blood cell energy and antioxidant defenses…

This study aims to create a single, standardized test to measure how well people tolerate low oxygen (hypoxia) during exercise. Researchers will study 50 physically active adults to see why some handle it better than others, looking at factors like breathing, heart rate, and lung…

This study checks how accurately a new pulse oximeter (a device that measures blood oxygen through the skin) works when oxygen levels are dangerously low. Twelve healthy volunteers will have their oxygen temporarily lowered in a controlled setting while the device's readings are …
