Utility of overnight oximetry indices in the evaluation of children with snoring and suspected obstructive sleep apnea.

Study Objectives: Optimal cutoff values of oximetry indices that differentiate obstructive sleep apnea (OSA) from primary snoring (PS) is not well established. Our study aimed to assess the utility of overnight oximetry indices in differentiating PS from OSA and assessing OSA severity, compared to polysomnography (PSG), in children with suspected OSA.

Methods: This was a retrospective study of children (1-18 years) with snoring who underwent PSG.
