Abstract: Obstructive Sleep Apnea (OSA) is a prevalent respiratory disorder, often diagnosed through polysomnography. Moderate-severe OSA significantly raises morbidity and mortality. However, patients commonly encounter accessibility challenges and prolonged waiting times. The STOP-BANG score, while sensitive, has low specificity. Studies using pulse oximeters, particularly with the oxygen desaturation index (ODI) as the diagnostic threshold, have been conducted. In an effort to enhance screening precision and accessibility, we utilized the Wellue O2 ring, a commercial pulse oximeter ring, for screening moderate-severe OSA. This prospective pilot study, conducted at the Thammasat Sleep Center, enrolled patients aged ≥ 15 years. Patients wore the O2 ring on their thumb during polysomnography, and the O2 ring data were compared with polysomnography data post-examination. Among the 192 participants, 53.1% were male, with an average age of 49 years. 15.1% exhibited normal or mild OSA, while 84.9% had moderate-severe OSA. The Wellue O2 ring demonstrated high accuracy in screening moderate-severe OSA, with a sensitivity and specificity of 86.5% and 86.2%, respectively, using an ODI of 15 for 20 seconds. The test's area under the curve was 0.92. The Wellue O2 ring emerges as a promising alternative for screening moderate-severe OSA. This pilot study suggests its high sensitivity and specificity, positioning it as a convenient and accessible substitute for in-laboratory polysomnography. However, larger studies with diverse populations are essential to validate results and establish the device's clinical utility in OSA diagnosis.
