This completed study tested how accurately a new pulse oximeter (a device that clips onto a finger to measure blood oxygen) works in healthy volunteers whose oxygen levels were temporarily lowered in a controlled setting. Researchers compared the device's readings to actual blood…

This study tested a pulse oximeter device that measures blood oxygen and pulse rate without needles. Eleven healthy volunteers had their oxygen levels temporarily lowered in a controlled way to see how accurate the device was compared to blood samples. The goal was to check if th…

This study tested how accurately a new pulse oximeter (a device that shines light through the skin to measure blood oxygen) works in 13 healthy adults whose oxygen levels were temporarily lowered. The device's readings were compared to actual blood samples and heart monitors. The…

This study checked how well a pulse oximeter (a device that shines light through the skin to measure blood oxygen) works when people are moving and have very low oxygen levels. Five healthy adults had their oxygen levels temporarily lowered while using the device. The goal was to…

This study checked how well a specific pulse oximeter (a device that clips onto a finger to measure blood oxygen) works in healthy volunteers whose oxygen levels were deliberately lowered to very low levels. Eleven adults took part. The goal was to see if the device's readings ma…
