Samsung Galaxy Watch 4 study shows its SpO2 blood oxygen sensor to be impressively accurate

Samsung Galaxy Watch 4 study shows that its SpO2 blood oxygen sensor is accurate enough to compare to medical tools.

The days when watches were just time counters are over, thanks to the innovation of smartwatches, which have introduced various fancy features and handy health capabilities.

And as such, smart wearables these days have evolved intricately into reliable health trackers, which include monitoring physical activities, real-time heart rate, and sleep patterns of their users.

But are these health monitoring features really that accurate? Well, the latest study from no less than Samsung shows us that.

Samsung Galaxy Watch 4 SpO2 Blood Oxygen Sensor Study

According to a report by WCCFTech, the Samsung Galaxy Watch, especially the Series 4, accurately measures Obstructive Sleep Apnea (OSA).

South Korean tech giant Samsung Electronics and its Samsung Medical Center conducted a study on the effectiveness of the Galaxy Watch 4’s SpO2 or blood oxygen sensor.

Samsung’s study primarily checked the accuracy of its smartwatch’s blood oxygen sensor in detecting any symptoms of OSA.

To do this, researchers from the folks at Samsung used a Galaxy Watch 4 to track the blood oxygen levels of a total of 97 adults with various sleep disorders.

Galaxy Watch 4 blood oxygen sensor: how accurate is it?

The study monitored the blood oxygen of the 97 adults using the Galaxy Watch 4’s health sensors, along with medical equipment that also tracked their oxygen levels to do a side-by-side comparison.

According to a recent report by android Font, The researchers then monitored the participants’ peripheral oxygen saturation in two ways: via the smart wearable and traditional medical equipment.

Samsung published its study in the National Sleep Foundation’s Sleep Health Journal, showing impressive results in favor of the Galaxy Watch 4.

Research shows that the readings from the medical equipment and the smartwatch are incredibly parallel.

This basically means that the Galaxy Watch 4 could accurately monitor the oxygen saturation of its users while they doze off.

Android Police notes that the study further pointed out that OSA disorder is quite common these days. In fact, research has dropped some numbers, confirming that around 38% of adults currently struggle with the sleep disorder.

To be more specific, about 25% of middle-aged women suffer from moderate to severe OSA, while 50% of middle-aged men also suffer from sleep disorders.
