Respiratory Events with Pediatric Criteria in the Subset of Subjects Aged 13-18 Years (32 Patients)

	Median	Range	Limit of normality
Age (years)	15.8	13.3–18.7
Apnea hypopnea index (N/h)	0.0	0.0–0.9	0.8
Obstructive apnea index (N/h)	0.0	0.0–0.5	0.1
Hypopnea index (N/h)	0.0	0.0–0.9	0.8
Central apnea index (N/h)	0.06	0.0–0.6	0.4
% TST with end-tidal CO2 > 50 torr	0.2	0.0–64.6	24.0
Peak end-tidal CO2 (torr)	50.0	45.0–54.0	53.0
% TST with SpO2 <92%	0.0	0.0–1.5	1.0
SpO2 Nadir (mm Hg)	93.0	88.0–97.0	89.0

TST, total sleep time; SpO₂, oxyhemoglobin saturation.

The limit of normality was calculated as the 95th percentile for all the parameters, except for SpO₂ nadir that was calculated as the 5th percentile.
