This is the device that vibrates to stimulate a snorer into shifting positions when it detects a drop of oxygen saturation in the blood. The Snore Reducing Oxygen Level Monitor’s pulse oximeter secures around the thumb and uses a patented sensor to track one’s heart rate and SpO2 levels. When a drop in the amount of oxygen in the blood is detected (a common side effect of snoring), the adjustable wristband silently vibrates to stir the snorer into changing a sleeping position. As a fitness band, it records heart rate, steps, and motion, and it vibrates to remind the wearer when it’s time to walk or exercise.
