Sponsor's own description

This study focuses on a comprehensive examination of obese patients with sleep-related breathing disorders including patients with OSA, sleep hypoventilation and OHS. The aim of this study is to (1) evaluate characteristics of and differences between severity levels of obesity-related breathing disorders, (2) discuss pathophysiological variables associated with hypoventilation during sleep or at daytime and (3) find functional parameters indicating sleep hypoventilation.
