Utility of A Type Ⅲ Portable Monitor for Diagnosis of OSA

Study Objectives:This study aims to compare NOX T3 study at-home to in-lab polysomnogram and simultaneous NOX T3 study.Secondly,we aim to compare the diagnostic accuracy of the NOX T3 portable sleep monitor to that of simultaneously recorded in-lab polysomnogram(PSG) in adults being evaluated for obstructive sleep apnea(OSA).Methods:A total of 81 participants were recruited following face-to-face evaluation at PKU People's hospital'ssleep center.All participants initially performed an overnight HST using the Nox-T3 portable monitor.Within 2 weeks of the HST,participants performed an in-laboratory PSG with a simultaneous Nox-T3 portable monitor recording.PSG records were manually scored using the American Academy of Sleep Medicine(AASM) criteria,and PM records were double-scored using the device's autoscore algorithm as well as manual scoring.Two separate manually edited scorings were performed using different definitions for hypopnea in both HST and PSG,1) events with ≥ 30%reduction in airflow from baseline f...Study Objectives:This study aims to compare NOX T3 study at-home to in-lab polysomnogram and simultaneous NOX T3 study.Secondly,we aim to compare the diagnostic accuracy of the NOX T3 portable sleep monitor to that of simultaneously recorded in-lab polysomnogram(PSG) in adults being evaluated for obstructive sleep apnea(OSA).Methods:A total of 81 participants were recruited following face-to-face evaluation at PKU People's hospital'ssleep center.All participants initially performed an overnight HST using t中国睡眠研究会
