Obstructive sleep apnea: an experience

International Journal of Medical Science and Public Health, 2016

Background: Obstructive sleep apnea (OSA) is a common disorder of repetitive pharyngeal collapse during sleep. It is more common among middle-aged adults. Obesity leads to and intensifies OSA. Epidemiologic studies have recorded relations of OSA with hypertension. The Berlin Questionnaire may find persons at high possibility for OSA and hence can evade costly polysomnography (PSG) studies, especially in resource-limited settings. This study is about our experience of Berlin Questionnaire and clinical characteristics of patients with OSA. Objective: To reveal our experience of OSA in terms of (i) age/sex distribution; (ii) Berlin Questionnaire utility; (iii) clinical features; (iv) polysomnograhic findings; and (v) association with obesity and hypertension.

Obstructive Sleep Apnea: A Review Article

2021

Obstructive sleep apnea is characterized by repetitive episodes of complete or partial collapse of the upper airway during sleep. Prevalence of obstructive sleep apnea is favored in men more than woman with a ratio of 2-4:1. Risk factors include nasal obstruction, obesity, gender, craniofacial anatomy, and smoking. Reoccurring symptoms, such as daytime sleepiness and irregular snoring have lead scientists and doctors to further find appropriate means of diagnosis. Polysomnography is proved to be the golden-standard method for diagnosing obstructive sleep apnea. Other diagnostic tools include taking a home apnea test. Positive airway pressure and oral appliances are the two most common noninvasive devices used to treat obstructive sleep apnea. Surgical procedures, like uvulopalatopharyngoplasty and maxillomandibular advancement are the most effective surgeries, especially in severe cases. Obstructive sleep apnea also arises complications and side effects that do not only affect the p...

Analysis of Comparative Studies on Obstructive Sleep Apnea and Different Modes of Management

https://www.ijrrjournal.com/IJRR\_Vol.7\_Issue.9\_Sep2020/Abstract\_IJRR0046.html, 2020

Obstructive Sleep Apnea (OSA) is a common disorder with episodes of recurrent and intermittent cessation of breathing due to collapse of upper airway during sleep. This phenomenon happens because of abnormality in the neurological coordination in sleep leading to upper airways musculature instability. OSA Syndrome presents mostly in obese individual with snoring, recurrent intermittent hypoxia, sleep fragmentation leading to excessive daytime somnolence. It is associated with increased cardiovascular morbidity and mortality. Different treatment options are now available for effective management. However, even after four decades, Continuous positive airway pressure (CPAP) is still considered the gold standard treatment. Regular usage of CPAP is effective in improving the quality of life and reducing the clinical sequelae of obstructive sleep apnea.

Obstructive Sleep Apnea An Emerging Problem

Heal Talk, 2020

Obstructive sleep apnea is potentially sleep disorder with multiple of negative consequences on patients health and society .OSA Symptoms include loud snoring, daytime sleepiness and restless sleep. The ''gold standard'' of detection is by polysomnography, a detailed history and physical examination may help uncover previously undiagnosed cases. Under diagnosed obstructive sleep apnea can cause heart disease, hypertension, depression, and even death. Several other modalities exist for treating obstructive sleep apnea, including continuous positive airway pressure (CPAP), oral appliances and several surgical procedures. Conservative approaches like weight loss, alcohol and tobacco cessation are also strongly encouraged in the patient with obstructive sleep apnea. With increased awareness a multidisciplinary approach is necessary for an accurate management of the disease.

Obstructive Sleep Apnea -A Review Review Article

SciDoc Publishers, 2020

Obstructive sleep apnea (OSA) is a common sleeping disorder. As the name suggests, it is associated with apneic and hypopneic breathing due to some kind of obstruction in the respiratory passage and thereby interferes with sleep. This review aims to give a concise overview on the disease, its pathophysiology, clinical presentation, diagnosis and various methods of management.

Study of obstructive sleep apnea in respiratory disorders

100 patients having respiratory complaints were selected randomly from OPD and were screened for by symptomatology, history, clinical examination, Chest X ray & spirometry and were analyzed for various respiratory diseases. The youngest subject was 30 yrs old and the oldest 75 years. In the study, 75% were males and 25% were females. Polysomnography was performed in these subjects. Patients were distributed as regards the severity of Obstructive Sleep Apnea (OSA).OSA was detected in 45, of these 45% had mild, 35% moderate and 20% had severe OSA. A linear relationship was found between Body Mass Index (BMI) and severity of OSA as also between neck circumference and severity of OSA. No correlation was detected between Diabetes Mellitus and OSA. Whereas, there was a significant impact of systemic hypertension on OSA.

Obstructive sleep apnea syndrome: a literature review

Minerva stomatologica, 2015

Obstructive sleep apnea syndrome (OSAS) is a complete or partial airway obstruction that can cause significant physiologic disturbance with various clinical impacts. The etiology is multifactorial and its clinical manifestations are night snoring, headache when patient wakes up, day-time sleepiness and degrease of cognitive performance. Some recent international studies suggest that the OSAS prevalence is 2-4% in men and 1-2% in women of average age. The aim of this work was presenting a literature review in Medline concerning Obstructive sleep apnea syndrome. A review of the articles ranging from 1980 to 2014 has been done. Over 2000 articles were found and those which give useful information about etiology, diagnosis, therapy and found results after the study were selected and evaluated. In literature there is no unanimous opinion on the treatment of OSAS. According to the majority of the authors it should be multidisciplinary. The choice of therapy is predicated on the etiology, ...

Obstructive Sleep Apnea (OSA) as a Cause of Sleep Disorders

eScientific, 2021

Introduction: OSA is a medical disorder characterized by repeated episodes of the upper airway closure during sleep. The correct diagnosis of OSA is essential, through a complete clinical history and thorough evaluation of the anatomical area of the upper airway. Literature Review: The inability to recognize OSA can adversely affect health conditions, as this disease is associated with significant morbidity and mortality. Obesity is a major risk factor for the incidence of OSA. Surgical management was considered in patients with AHI> 15 events / hour and unable to tolerate or reject CPAP. Conclusion: Identifying the pattern and pathophysiology of airway obstruction in OSA is essential. The gold standard examination for OSA is polysomnography. An initial oropharyngeal anatomical evaluation to predict success management of OSA patients is necessary.
