Abstract

Objective: To assess obstructive sleep apnea syndrome (OSAS) severity among pediatric patients. Design. A retrospective review of charts and polysomnography (PSG) results.

Measurements and main results: Apnea-hypopnea index (AHI) and the cumulative duration of sleep while O(2)SAT was <91% were determined in 389 patients with OSAS. Patients with AHI ranging <5, 5 to 15, 16 to 30, and >30, had mean lowest observed O(2)SAT values of 88% +/- 8%, 85% +/- 9%, 78% +/- 12%, and 69% +/- 13%, respectively. The patients spent a mean of 3.5% +/- 9.2 % of their sleep time with O(2)SAT < 91%. AHI values showed a poor linear correlation with the lowest measured O(2)SAT values. Body mass index percentiles showed no significant linear correlation with AHI values or with the lowest measured values of O(2)SAT.

Conclusion: Values of AHI cannot accurately predict severity of oxyhemoglobin desaturation in pediatric OSAS and vice versa. No significant correlation between body mass index percentiles and severity of OSAS was established.
