NCT Number: NCT04121923
The purpose of this study is to evaluate the sensitivity and specificity of the Belun Ring Pulse Oximetry system for screening of obstructive sleep apnea (OSA) in adults during standard polysomnography sleep study conditions. The primary outcome metric is the Apnea-Hypopnea Index (AHI).
The goal, in its entirety, is to evaluate the performance of the Belun Ring Pulse Oximeter during a standard polysomnography sleep study and its ability to compare to the determined Apnea-Hypopnea Index (AHI) of the subjects. It is expected that the Belun Ring Pulse Oximeter will adequately record SpO2, pulse rate, body position and heart rate variability throughout the duration of the study.

Inclusion criteria
Exclusion criteria
Belun Ring Pulse Oximeter allows measurement and analysis of oximetry, pulse rate, photo-plethysmography (PPG), and accelerometer signals from the proximal phalanx of index finger. Total sleep time (Ring-TST) and respiratory event index (Ring-REI) are estimated
Time frame: 1 overnight sleep study (1 Day)
Apnea-Hypopnea Index (AHI) is defined as the total number of apnea and hypopnea events per hour of sleep, where higher values indicate more severe sleep-disordered breathing. In this study, standard overnight polysomnography(PSG) and Belun Ring pulse oximeter were simultaneously measured. The AHI derived from PSG data was served as the reference.
The primary outcome evaluates the accuracy of the Belun Ring by calculating the difference in Ring-REI by the Belun Ring compared with AHI derived from PSG recordings for each participant. The difference was calculated as:
Ring-REI (Belun Ring) - AHI (PSG).
Negative values indicate that the Belun Ring estimated a lower AHI than PSG, while positive values indicate that the Belun Ring estimated a higher AHI than PSG.
Summary statistics of these differences were used to assess agreement between the Belun Ring device and PSG in measuring sleep apnea severity.
