Summary

OSA is commonly diagnosed with either attended in-lab polysomnography (PSG) or unattended home sleep apnea testing (HSAT). The BLS-100 (Belun Technology Company Limited, Hong Kong) is a novel neural network-based HSAT platform consists of a ring shape pulse oximeter sensor, a cradle, and an improved proprietary analytic algorithm. This study investigates the hypothesis that the BLS-100 is a reasonable HSAT device for OSA assessment.

Interventions

DEVICE

Belun Ring

The Belun Ring sensor will be applied to the proximal phalanx of the index finger in the non-dominant hand of the participating individuals prior to their sleep onset in the sleep lab and will be removed upon awakening at the end of the sleep period on the following morning. The attended in-lab sleep study will be performed simultaneously in a standard fashion.

DIAGNOSTIC_TEST

PSG

All patients scheduled for attended overnight in-lab polysomnography (PSG) in our 2 sleep labs will undergo PSG testing. On the same night of the PSG testing, these same patients will also wear the Belun Ring device. After the study, we will compare results of the Belun Ring device vis-à-vis with the results of the PSG on the same patient.
