Study claims Samsung Galaxy Watch4 sensors closely comparable to medical tools

Research published in the Sleep Health journal claimed that Samsung Galaxy Watch4 sensors for SpO2 are comparable to actual medical tools when measuring OSA, or obstructive sleep apnea. According to the study, readings taken simultaneously with the wearable and traditional medical equipment were adjusted.

The study was conducted by seven doctors, six of whom are affiliated with Samsung Electronics. It took place at Samsung Medical Center, which also paid for the research, so perhaps we should take its findings with a healthy dose of salt.

During the research, it was determined that the blood oxygen sensor on the back of the Galaxy Watch4 can provide real insight into the user’s health, and it complies with FDA and ISO standards when the average error in data is less than 4%.

The researchers found that the wearable sensor is slightly more reliable than standard wrist-worn medical instruments because they collect oxygen data differently—the Samsung device relies on pulse oximetry (readings of the pulse through the skin), while medical instruments rely of CO oximeter (readings of oxygen through the skin).

Research into OSA is important because, according to the study, 38% of adults suffer from some kind of sleep disorder, including 50% of all adult men and 25% of all adult women.
