Smartwatches have come a long, long way, however, you need to understand that they are still not full replacements for other more robust health & medical monitoring tools. It has been some time since the smartwatches started offering sensors such as SpO2 but every time we see a smartwatch come with such as sensor, we are informed that the sensors on these watches are not actual replacements for medical-grade tools or sensors that are used in medical industry. Now, a latest report shows that the Galaxy Watch 4 could become a really useful tool for medical purposes. Based on the report, the Galaxy Watch 4 could become an important tool for accurate measurement of OSA (Obstructive Sleep Apnea) shows a study conducted by Samsung Medical Center and Samsung Electronics. The study was published by National Sleep Foundation medical journal "Sleep Health," monitored 97 adults with sleep disturbances and concluded that the Galaxy Watch 4 could potentially help overcome the high cost associated with the traditional tools that are used for measurement. The Galaxy Watch 4 is equipped with a reflectance pulse oximeter module that stays in touch with the skin of the wearer when they are wearing the watch. The SpO2 sensor also brings 8 photodiodes that manage to sense the reflected light and captures PPG signals at a sampling frequency of 25Hz. For those who do not know, Obstructive Sleep Apnea is a common sleep disorder and an estimated of 38% adults actually suffer from this disorder. Up to 50% of men and 25% women in the middle-age populace actually face severe to moderate OSA. The researchers also discovered that the readings captured with the Samsung smartwatch and the traditional medical device simultaneously were aligned, and it proved that the Galaxy Watch 4 can actually take accurate measurements of oxygen saturation during sleep. This could help the Galaxy Watch 4 customer along with the future smartwatches cut down on medical bills as well as all the costs associated with in-hospital procedures.
