Gurugram, India – July 29, 2022: Galaxy Watch4 Series, which comes with a pulse oximeter module, could potentially help measure Obstructive Sleep Apnea, according to a study published by Sleep Health journal. Obstructive Sleep Apnea is a common sleep disorder, estimated to affect up to 38% of the general adult population.
The disorder is generally characterized by repetitive upper airway obstruction during sleep, resulting in oxygen desaturation, frequent arousals, and increased sympathetic activity.
The study found that wrist-worn trackers, like the Galaxy Watch4, were accurate in continuously measuring oxygen levels in trial patients, enabling researchers to screen for OSA by analyzing data collected by the wearable. Sleep Health is the journal of the National Sleep Foundation.
Samsung’s Galaxy Watch4 comes with a reflectance pulse oximeter module – located on the underside of the wearable and directly touching the skin – to measure oxygen saturation levels in peripheral blood (SpO2).
