A watch Galaxy Watch4 could potentially become a tool for accurate measurements of obstructive sleep apnea. This was shown by a study conducted by Samsung Medical Center Hospital and Samsung Electronics. A study that was published in a medical journal Sleep health, followed dozens of adults with sleep disorders and concluded that Galaxy Watch4 could help overcome the high costs associated with traditional measuring instruments.

Galaxy Watch4 are equipped with a reflective pulse oximeter module that remains in contact with the user's skin while worn. The SpO2 sensor also consists of eight photodiodes that sense reflected light and capture PPG (photoplethysmography) signals with a sampling rate of 25 Hz. In the study, researchers simultaneously measured 97 adults suffering from sleep disorders using Galaxy Watch4 and the traditional medical system. They found that the values captured by the Samsung watch and traditional medical equipment corresponded, proving that Galaxy Watch4 are actually capable of accurately measuring oxygen saturation during sleep. This could users Galaxy Watch4 to help reduce medical bills and costs associated with hospital procedures.

Obstructive sleep apnea (OSA) is a common sleep disorder. It is estimated that up to 38% of adults suffer from it. In middle age, up to 50% of men and 25% of women struggle with moderate and severe OSA. It looks like Samsung's smartwatches are getting better and better at health monitoring devices with each passing generation. Samsung is now apparently working on a sensor that allows body measurements temperature, which could already be available in his next watch Galaxy Watch5.
