Performance evaluation of a ring-worn pulse oximeter for the identification and monitoring of obstructive sleep apnea.

ABSTRACT:

Introduction

Obstructive sleep apnea (OSA) is a highly prevalent chronic disorder that is challenging to monitor clinically. While single-night laboratory-based polysomnography (PSG) is the current gold standard for OSA assessment, its utility is limited by cost and inaccessibility. Overnight pulse oximetry is a feasible approach for simplified at-home monitoring of OSA. In this study, we evaluate the performance of a modified finger-worn pulse oximetry device ("Ring") for OSA assessment.

Methods

In all, 25 patients with OSA [age: 55.5 ± 7.7 years (mean ± SD), body mass index (BMI): 31.8 ± 5.1 kg/m², 14M:11F, and Fitzpatrick scale score I-II: 15, III-IV: 6, and V-VI: 4] completed up to four in-laboratory PSG studies with simultaneous Ring oximetry measureme
