This study tested how accurately a Samsung Galaxy smartwatch can measure blood pressure over time. Researchers compared the watch's readings to those from a standard medical device used in clinics. The goal was to see if the smartwatch could be a reliable tool for people to monit…

This study aimed to find out if the finger you choose to place a pulse oximeter sensor on affects the oxygen level reading it gives. Researchers tested 24 healthy volunteers by having them briefly breathe air with low oxygen and high carbon dioxide while measuring oxygen levels f…

This study aimed to understand how breathing different gas mixtures—some with low oxygen or high carbon dioxide—affects basic body functions in healthy people. Fifteen volunteers breathed different gas combinations while researchers measured their heart function and blood flow. T…

This study tested how accurately three different smartwatches measure blood oxygen levels compared to a standard medical device. Eighteen healthy volunteers wore the watches while their oxygen levels were gradually lowered in a controlled setting. The goal was to see if consumer …

This study tested how different brands of pulse oximeters measure blood flow in healthy volunteers. Researchers compared readings from various devices while participants were at rest, moving, and with restricted circulation. The goal was to understand if these medical devices pro…
