Comparative Study[Comparison of diagnosis and localization methods in obstructive sleep apnea syndrome: apneagraph vs polysomnography and apneagraph vs endoscopy].
ApneaGragh is a new device for simultaneous determination of obstructive sleep apnoeic events and continuous pressure measurements for localization of upper airway obstructive site. This study is to evaluate the clinical value of it. ⋯ ApneaGraph can identify the level of upper airway obstruction more accurate than fiberoptic pharyngoscopy. In the meantime, it also can serve as a portable PSG to diagnose sleep disordered breathing qualitatively.
