Actual (reported)The purpose of this research study is to develop a way of predicting with computers how surgery on the airway will affect night time breathing called Obstructive Sleep Apnea (OSA) in children with Down Syndrome. A research measurement for airway resistance will also be done during the clinical sleep MRI. The airway resistance measurement will take about 10 minutes and is done during sleep. The airway resistance measurement is called critical closing pressure (Pcrit).
