Apnoea-hypopnoea indices determined via continuous positive airway pressure (AHI-CPAP) versus those determined by polysomnography (AHI-PSG): a protocol for a systematic review and meta-analysis.

BMJ Open 2021 05 10;11(5):e044499. Epub 2021 May 10.

Department of Respiratory Diseases, Univ Montpellier, CHU Montpellier, Montpellier, France.

Introduction: To date, continuous positive airway pressure (CPAP) remains the cornerstone of obstructive sleep apnoea treatment. CPAP data describing residual sleep-disordered breathing events (ie, the CPAP-measured apnoea-hypopnoea indices (AHI-CPAP)) is difficult to interpret because it is an entirely different metric than the polysomnography (PSG) measured AHI gold standard (AHI-PSG). Moreover, manufacturer definitions for apnoea and hypopnoea are not only different from those recommended for PSG scoring, but also different between manufacturers. Read More

Evaluation and Management of Adults with Obstructive Sleep Apnea Syndrome.

Lung 2021 04 13;199(2):87-101. Epub 2021 Mar 13.

Division of Pulmonary & Critical Care Medicine, University of Utah, 26 N 1900E, Salt Lake City, UT, 84112, USA.

Obstructive sleep apnea syndrome (OSAS) is a common and underdiagnosed medical condition characterized by recurrent sleep-dependent pauses and reductions in airflow. While a narrow, collapsible oropharynx plays a central role in the pathophysiology of OSAS, there are other equally important nonanatomic factors including sleep-stage dependent muscle tone, arousal threshold, and loop gain that drive obstructive apneas and hypopneas. Through mechanisms of intermittent hypoxemia, arousal-related sleep fragmentation, and intrathoracic pressure changes, OSAS impacts multiple organ systems. Read More
