Obstructive Sleep Apnea Hypopnea Syndrome

Obstructive sleep apnea hypopnea syndrome (OSAHS) is an important medical condition which is on the increase in the past 50 years. It causes significant morbidity and mortality in both developed and developing nations of the world. To review the relevant literature on obstructive sleep apnea. Literature review was carried out on the pathophysiology, clinical presentation, complications, diagnos...

Mean apnea–hypopnea duration (but not apnea–hypopnea index) is associated with worse hypertension in patients with obstructive sleep apnea

To determine which polysomnography parameters are associated with severity of hypertension.This retrospective study collected data on all patients admitted to our urban, academic center in Beijing with hypertension who had undergone polysomnograms (PSG) and were diagnosed with obstructive sleep apnea (OSA) (apnea-hyponea index [AHI] ≥5/hour). We then compared polysomnographic parameters (AHI, o...

Is Apnea-Hypopnea Index a proper measure for Obstructive Sleep Apnea severity?

Sleep Architecture in Patients With Primary Snoring and Obstructive Sleep Apnea

Introduction: This study aimed to investigate sleep architecture in patients with primary snoring and obstructive sleep apnea. Methods: In this study, we analyzed polysomnographic data of 391 clients who referred to Sleep Disorders Research Center (SDRS). These people were classified into three groups based on their Apnea-Hypopnea Index (AHI) and snoring; control, Primary Snoring (PS), and Obs...

Physiopathology of obstructive sleep apnea-hypopnea syndrome.

The physiopathology of obstructive sleep apnea syndrome is multifactorial. Gender and obesity status, as well as genetic, anatomic, and hormonal factors, together with ventilatory drive, interact in a diverse manner in the physiopathology and clinical expression of the disease. Obesity is the main risk factor, since increases in body mass index, visceral fat, and neck circumference are strong p...
