Belun Ring Validation Study for Assessment of Obstructive Sleep Apnea

This study aims to determine the overall accuracy, sensitivity, and specificity of the Belun Ring device in evaluating obstructive sleep apnea by comparing the device to the attended overnight in-lab polysomnography which is the gold standard for diagnosis of obstructive sleep apnea. Our hypothesis is that the Belun-Ring, a type 4 portable monitoring device, is overall sensitive and specific for evaluation of obstructive sleep apnea when compared to the attended overnight in-lab polysomnography.
