WebUpper airway resistance syndrome (UARS) is a condition that was first identified and described at Stanford University. It is very similar to obstructive sleep apnea (OSA) in that the soft tissue of the throat relaxes, reduces the size of the airway, and results in disturbed sleep and consequent daytime impairment, including excessive daytime sleepiness.
