Background: Oximetry was proposed as an abbreviated exam, easily accepted by the child, for the diagnosis of obstructive sleep apnea (OSA) for children located in regions where access to pediatric sleep labs is limited. The objective of this study was to determine the diagnostic value of the oxygen desaturation index (ODI), the number of ≥ 3% oxygen desaturations per hour of recording, obtained by portable oximetry performed in parallel with video-polysomnography (PSG), in a cohort of children, with and without comorbidities, referred for OSA.
Methods: Data from portable oximetry performed in parallel with PSG were prospectively collected.
Polysomnography (PSG) is the gold standard for diagnosing obstructive sleep apnea (OSA) in children but not always available. Abbreviated exams exist, such as respiratory polygraphy (RP), but are less accurate for OSA diagnosis. Video recording (video-RP) may provide a more precise estimation of the total sleep time (TST) compared to RP alone.
