Abstract
Objective: A novel ring-worn oximeter (Circul) uses reflective photoplethysmography and automated signal processing to calculate oxygen desaturations. We evaluated the ability of Circul to detect obstructive sleep apnea in Chinese adults. Methods: We recruited 207 Chinese Han subjects: 70% males, mean age 48.2[+ or -]14.7 years, mean BMI 27.6[+ or -]4.8 kg/m2 and mean AHI 28.6[+ or -]25.2 events/h. All participants underwent simultaneous polysomnography (PSG) and Circul testing in a sleep laboratory. Oxygen desaturation index (ODI), mean oxygen saturation (MSp[O.sub.2]), cumulative time at SpO2 Results: The ODI was 25.3[+ or -]24.5 events/h using PSG and 22.2[+ or -]24.5 events/h using Circul (P Conclusion: Circul ring pulse oximetry can detect OSA with reasonable reliability. The Circul system is a reliable and comfortable choice for OSA assessment. Keywords: obstructive sleep apnea, reflective photoplethysmography, pulse oximetry, polysomnography
