A new approach in the diagnosis of upper airway resistance syndrome (UARS): PAP method

Abstract

Introduction: Upper airway resistance syndrome (UARS) is characterized by repeated number of arousals at night, and excessive daytime sleepiness or somnolence (EDS). It is often missed in classical polysomnographic diagnostic approaches and misdiagnosed as simple snoring or idiopathic hypersomnia, thereby is often left untreated. We propose that positive airway pressure (PAP), which has shown to be effective against UARS, can be used as a diagnostic tool as well. The study designed to test whether patients with high titration pressures can be diagnosed for UARS, and whether this pressure can be used as the treatment pressure in UARS.
