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

ABSTRACT:

Study objectives

Optimal cutoff values of oximetry indices that differentiate obstructive sleep apnea (OSA) from primary snoring (PS) are 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, in children with suspected OSA.

Methods

This was a retrospective study of children (1-18 years of age) with snoring who underwent polysomnography. Patients with Down syndrome, craniofacial anomalies, known genetic syndromes, neuromuscular conditions, or a central apnea index ≥ 5 were excluded. Demographic data, polysomnography variables, and oximetry indices (eg, oxygen desaturation index [ODI₃, defined as number of ≥ 3% desaturation episodes/h of artifa
