Which abbreviation corresponds to Upper Airway Resistance Syndrome?

Abbreviations in sleep medicine map directly to specific disorders, so the best match is the option that names the syndrome itself. Upper Airway Resistance Syndrome is abbreviated UARS, and the choice that presents the syndrome by its full name aligns with the expected abbreviation. The other options point to unrelated concepts: Sinoatrial relates to the heart’s pacemaker system; Sleep Disordered Breathing is a broader category that includes UARS but is not the abbreviation for this specific condition; Oxyhemoglobin saturation refers to blood oxygen levels. Clinically, UARS is a mild form of sleep-disordered breathing with increased upper airway resistance causing arousals and sleep fragmentation, often with little or no apnea on polysomnography.
