Publisher's Synopsis
Obstructive Sleep Apnea Hypopnea Syndrome (OSAHS) is a common condition affecting 5-14% of adults aged between 30 and 70, characterized by recurrent episodes of more or less complete obstruction of the upper airway (UAS) during sleep. SAHOS leads to iterative desaturations and micro-arousals, with a destructuring of sleep architecture, resulting in the cardiovascular and metabolic complications that make this pathology so serious.Although the definition, classification of severity and therapeutic approach to OSAH are mainly based on the apnea-hypopnea index (AHI), it is now well established that OSAH is not a single entity, but a complex, heterogeneous disease that encompasses many very different phenotypes. This heterogeneity stems from the multiplicity of risk factors, pathophysiological mechanisms, clinical presentations and the cardiovascular and metabolic consequences of obstructive events.
