  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 O2SAT 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 O2SAT 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 O2SAT < 91%. AHI values showed a poor linear correlation with the lowest measured O2SAT values. Body mass index percentiles showed no significant linear correlation with AHI values or with the lowest measured values of O2SAT. 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.
