Obstructive sleep apnea (OSA) is caused by repetitive partial or complete obstruction of the upper airway, characterized by episodes of breathing cessation during sleep, which last 10 or more seconds. The prevalence of OSA varies widely depending on the demographics of the population studied, the definition of the disorder and the methods of diagnosis. Patients with obstructive sleep apnea can ...

Background: Obstructive Sleep Apnea (OSA) is the most prevalent form of sleep disordered breathing and could become an important public health issue in India. Patients with OSA have high levels of sympathetic nerve activity during sleep. The autonomic alterations persist during wakefulness and are considered to contribute to the cardiovascular disorders associated with OSA. Aims & Objective: Th...

Sleep apnea is a common disorder in which breathing is briefly and repeatedly interrupted during sleep. There are three types of sleep apnea; Central sleep apnea, Obstructive sleep apnea, and Mixed or Complex sleep apnea. Obstructive sleep apnea (OSA) being more common, is characterized by obstruction of the upper airway and subsequently cessation of breathing during sleep. Various epidemiologi...

UNLABELLED Obstructive sleep apnea (OSA) has high prevalence and may cause serious comorbidities. The aim of this trial was to show if simple noninvasive methods such as gag reflex and palatal reflex are prospective multivariate assessments of predictor variables for OSA. METHOD We evaluate gag reflex and palatal reflex, of fifty-five adult patients, and their subsequent overnight polysomnogr...

Sleep apnea is defined as repetitive episodes of decreased or total cessation of respiratory airflow during sleep, leading to a fall in oxygen saturation of 4% and sleep fragmentation. Sleep apnea can be central or obstructive. Central sleep apnea (CSA) is characterized by apneas secondary to diminution or cessation of thoraco-abdominal respiratory movements (due to dysfunction of central respi...

background and objective: sleepiness is one of the important factors in motor vehicle accidents, especially in commercial drivers (cds). obstructive sleep apnea (osa) has an important role in developing sleepiness. the stop-bang questionnaire is used in medical examinations of commercial drivers in iran by law. this study aimed to investigate the judgment that drivers prefer not to report their...

www.thoracic.org C LI P A N D C O P Y What is Sleep Disordered Breathing (SDB)? SDB is a general term used to describe various different abnormalities in breathing pattern which occur during sleep, including obstructive and central sleep apnea. Obstructive sleep apnea (OSA) is a common disorder which affects roughly 10% of the US population and approximately 1/3 of people with congestive heart ...

Patel, Sanjay R. Shared genetic risk factors for obstructive sleep apnea and obesity. J Appl Physiol 99: 1600–1606, 2005; 10.1152/japplphysiol.00501.2005.—Both obesity and obstructive sleep apnea (OSA) are complex disorders with multiple risk factors, which interact in a complicated fashion to determine the overall phenotype. In addition to environmental risk factors, each disorder has a strong...

obstructive sleep apnea (osa) together with metabolic disorders is common in severely obese patients. weight reduction is considered as a treatment modality in these cases while few of them can succeed in considerable weight loss. here, we present a severely obese man with body mass index of 54 suffered from osa, type 2 diabetes, hypothyroidism, and hypertension. he intentionally lost 80 kilogr...

Abstract
 Background
 Chronic hypoxia may lead to auditory dysfunction in patients with obstructive sleep apnea (OSA), and this worsen OSA, creating a vicious circle. The aim of study was investigate tinnitus hearing loss OSA patients.
 Methods
 A total 147 were included the study. After polysomnography (PSG), an apnea-hypopnea index (AHI) ≥ 5 group, ones AHI
