Sleep-disordered breathing (SDB), which includes obstructive sleep apnea (OSA) as its most extreme variant, is characterized by intermittent episodes of partial or complete obstruction of the upper airway during sleep that disrupts normal ventilation and sleep architecture and is typically associated with snoring and daytime sleepiness. SDB is common, with an incidence in middle-aged men and wo...

OBJECTIVE Sleep-disordered breathing (SDB) is among the most common diseases and includes a group of pathological conditions that form a severity continuum from primary snoring (PS) to obstructive sleep apnea (OSA). SDB presents a multifactorial etiology and in children, it is often linked to adenotonsillar hypertrophy, which may lead to an alteration of the breathing pattern. Therefore, severa...

INTRODUCTION: It is well known that obesity is a risk factor for sleep-disordered breathing (SDB). However, whether SDB predicts increase in BMI is not well defined. Data from the Sleep Heart Health Study (SHHS) were analyzed to determine whether SDB predicts longitudinal increase in BMI, adjusted for confounding factors. METHODS: A full-montage unattended home polysomnogram (PSG) and body ant...

To investigate the associations between amount of habitual alcohol consumption (HAC) and prevalence of metabolic syndrome (MetS), sleep, and sleep-disordered breathing (SDB). We enrolled 683 untreated SDB male patients (age: 54.4 ± 7.80 y, apnea-hypopnea index (AHI): 29.0 ± 21.53/h). HAC was assessed as the average number of drinks consumed per week during the past 12 months. Anthropometric and...

Sleep-disordered breathing (SDB) in children is assessed by quantification of hypopnea and apnea events. Little is known, however, about respiratory timing and breath-to-breath variability during sleep. The aim of this study was to investigate respiratory parameters across sleep stages in children with SDB before and after treatment compared with healthy children. Overnight polysomnography (PSG...

Sleep-disordered breathing (SDB) has a close relation to heart failure (HF), the incidence of fatal cardiovascular events, and mortality.1 Adaptive servo-ventilation (ASV) therapy has been shown to be effective for central sleep apnea (CSA) and Cheyne–Stokes respiration (CSR).2,3 Recently, ASV therapy has also been used to treat patients with HF who also have CSA and CSR2,4,5 as well as patient...

BACKGROUND Obstructive sleep apnea is a clinical disorder characterized by loud snoring, apneic episodes, and chronic sleep disruption. Collegiate football players exhibit several risk factors for OSA, including large neck circumference and high body mass index, although the prevalence of OSA in this cohort is unknown. METHODS The STOP-BANG questionnaire was administered at random to members ...

Obstructive sleep apnea/hypopnea syndrome (OSA/HS) is the basis of the spectrum of sleep-disordered breathing (SDB) and is a condition characterized by the presence of snoring, repetitive partial upper airway obstruction (hypopnea) and/or intermittent complete obstruction (apnea), long enough to cause reduce the level of oxygen in the blood (desaturation), fragmented sleep and excessive daytime...

Sleep disordered breathing (SDB) consists of snoring, upper airway resistance syndrome and obstructive sleep apnea.OSA is characterized by repeated pharyngeal collapse pharynx (partial or complete) in sleep resulting in cyclical hypoxemia. A combination of anatomical factors and muscular hypotonia of pharyngeal muscles is often responsible for this closure during inspiration. Sympathetic stimul...
