Children will be recruited from each site's sleep clinics and laboratories, Down syndrome clinics and otolaryngology clinics. Community recruitment will be coordinated with local Down Syndrome Associations.\n\nChildren who agree to participate in the study will be screened for eligibility based on history, physical examination, and review of medical records including history of congenital heart disease and Pulmonary Hypertension (PHTN), and use of Continuous Positive Airway Pressure (CPAP). Children eligible for the study are those with persistent obstructive apnea after adenotonsillectomy or children with obstructive sleep apnea without adenotonsillar hypertrophy or in situations when parents refuse adenotonsillectomy.. The enrollment PSG eligibility will be determined by central scoring of either a research Polysomnography (PSG). In addition to an oxygen titration PSG, which determines responsiveness to oxygen, participants will be asked to wear a wrist actigraph and undergo neurocognitive testing, echocardiography, physical examination, anthropometry, and venipuncture. Caregivers will complete questionnaires to assess their child's emotional, physical, social, and school functioning, sleep quality; child's behavior and cognitive function, and will complete a sleep diary that is used concurrently with their child's use of a wrist actigraph. The latter includes caregiver completion of the \"Behavior Rating Inventory of Executive Function\" (BRIEF2), a co-primary outcome.\n\nAt 3 months, caregivers will complete the BRIEF2. At 6 months, all baseline studies and a PSG will be repeated.\n\nAt baseline, demographic data will be collected, including information on residential address (for use in geocoding).",[151,157],{"label":152,"type":153,"description":154,"interventionNames":155},"Oxygen plus supportive care (OXT)","ACTIVE_COMPARATOR","Nocturnal oxygen therapy plus providing patient with
