The sensors on the Samsung Galaxy Watch4 are quite comparable to medical instruments

According to a study published in the Sleep Health journal, Samsung Galaxy Watch4 sensors for SpO2 are comparable to actual medical instruments when measuring OSA or Obstructive Sleep Apnea. Readings taken simultaneously with the wearable and the conventional medical equipment were aligned according to the research.

Samsung Electronics researchers conducted the research, which included seven medical professionals from Samsung Electronics. The study took place at Samsung Medical Center, which paid for it, so we should take its findings with a grain of salt.

The blood oxygen sensor on the Galaxy Watch4's back was found to provide a genuine insight into a user's health, and it complies with FDA and ISO standards when the mean error in data is less than 4%.

The researchers discovered that the wearable sensor is more trustworthy than a medical device worn on the wrist since it takes oxygen data differently - whereas Samsung's technique relies on pulse oximetry (readings of the pulse through the skin), and conventional instruments employ CO-oximeter (readings of oxygen through the skin).

According to a recent research, 38% of individuals experience some sort of OSA sleep disruption, including 50% of all adult males and 25% of all adult females.
