Variable Response to CPAP in a Case of Severe Obstructive Sleep Apnea: An Unusual Cause

摘要

The objective of this report is to present clinical and scientific evidence to support the role of head position in the management of obstructive sleep apnea (OSA) with positive airway pressure. OSA, characterized by repetitive obstruction of the upper is a common medical condition associated with daytime somnolence, morning headaches, mood disturbances, and a variety of cardiopulmonary complications. The role of head position during obstructive respiratory events has been largely overlooked. We present a case where OSA severity decreased significantly with the head rotated in the right lateral position compared to head position in the neutral and left position. This case demonstrates an important influence of head position during continuous positive airway pressure titration, independent of trunk position and sleep stage, in patients with OSA, and highlights the utility of the video polysomnography for identifying the variant.Citation:Gandotra K, May A, Auckley D.
