Obstructive sleep apnoea hypopnoea syndrome (OSAHS) is a common cause of breathing-related sleep disorder, causing excessive daytime sleepiness. Common clinical features of OSAHS include snoring, fragmented sleep, daytime somnolence and fatigue. This article aims to provide a comprehensive review of the condition, including its management.

Sleep apnea-hypopnea syndrome (SAHS) is associated with an increased risk of cardiovascular disease.1-4 The pathogenic bases for this association are unknown, but one of the possible mechanisms involved is oxidative stress.5 It has been suggested that the intermittent hypoxia and episodes of hypoxia/reoxygenation that accompany apneas may lead to increased vascular release of free radicals, fav...

Detection of desaturations on the pulse oximetry signal is of great importance for the diagnosis of sleep apneas. Using the counting of desaturations, an index can be built to help in the diagnosis of severe cases of obstructive sleep apnea-hypopnea syndrome. It is important to have automatic detection methods that allows the screening for this syndrome, reducing the need of the expensive polys...

Objective: To investigate the curative effect of the plasma low-temperature radiofrequency ablation (RFA) on ineffective obstructive sleep apnea hypopnea syndrome (OSAHS) after uvulopalatopharyngoplasty (UPPP). Method: 39 cases of OSAHS which were ineffective after UPPP were chosen to accept RFA. Preoperative apnea hypopnea index (AHI), lowest saturation of blood oxygen (LSaO2), snoring scale a...
