Filter by:The purpose of this study is to evaluate new iterations/generations of the ApniCure sleep therapy device.
The objective of this study is to assess the feasibility and safety of tongue suspension using the Siesta Medical Encore Tongue Suspension System for the treatment of obstructive sleep apnea (OSA).
Subjects with Obstructive Sleep Apnea (OSA) are at increased risk of developing cardiometabolic complications, and effective long-term nCPAP treatment significantly reduces the risk of cardiovascular morbidity and mortality.
The purpose of this study is to develop the hypoxemia prediction model during fiberoptic bronchoscopy under MAC(monitored anesthesia care) anesthesia.
Background: The oral appliances have been increasingly used in the treatment of primary snoring and in patients with mild obstructive sleep apnea syndrome besides being treatment options in adults with moderate to severe sleep apnea who did not accept or adapt to continuous positive airway pressure (CPAP). It is not well established yet in the literature, which patients with mild to moderate OSA will present a good response to treatment with oral appliances. Objective: To determine a value of CPAP pressure that correlates with a favorable response to the use of oral appliance in patients with mild to moderate sleep apnea. Patients and Methods: Two groups of 30 male patients (25-65 years, body mass index < 35 kg/m2) will be selected: the first group with an apnea-hypopnea index (AHI) between 5 and 15 events per hour of sleep and the second one with an AHI between 15 and 30 events per hour of sleep. Each patient will undergo three polysomnographic recordings (baseline, CPAP titration, after two months of treatment with oral appliance). Subjective (sleep disorders questionnaire, the Epworth Sleepiness Scale, and sleep diaries) and objective (polysomnography) parameters of sleep will be evaluated, besides the quality of life (SF-36), mood (POMS), and anthropometric measurements (neck circumference and craniofacial characteristic). Good response to treatment with the AIO will be considered as a 50% reduction in the baseline AHI index or AHI after treatment less than 5 events per hour of sleep.
Obstructive sleep apnoea (OSA) is a serious and common disorder affecting one in twenty-five men and one in fifty women over the age of 30. This breathing abnormality occurs during sleep and is characterised by snoring and episodes of sleep disturbances. The symptoms of untreated OSA (e.g. excessive daytime sleepiness), can result in significant reductions in the patients' quality of life. The key treatment modalities today include Continuous Positive Air Pressure (CPAP), surgery and the use of oral appliances (OAs). Increasingly, OAs have been advocated in the treatment of the symptoms of OSA since they offer a non-invasive form of treatment and also because patients often prefer this treatment to other treatment modalities. There is increasing evidence to support the effectiveness of OAs in the management of OSA, at least as a short term measure. What is still unclear is which types of OA are most effective and whether OAs are effective in the long term management of OSA. This randomized clinical trial aims to evaluate two differently designed OAs in terms of their effect on patients' quality of life and on the physiological symptoms of OSA (apnoea/hypopnoea index AHI). Around 45 patients with OSA will be recruited from a pool of patients referred to the dental hospital for treatment from the medical faculty. The treatment with OAs will commence after randomization to two treatment groups; follow-up examinations will take place over a period of 12 months. The results of this study will help inform practitioners and patients of the feasibility of using OAs in the long term management of OSA and help determine the most appropriate type of OAs for the management of OSA and improvement in quality of life.
CPAP, the standard treatment for Obstructive sleep apnea syndrome (OSAS) that reduces sleep fragmentations and neurocognitive deficit in OSAS may also have a key role in reduction of cardiovascular, mortality risks in the same patients.
Continuous positive airway pressure (CPAP) is the most commonly used treatment for obstructive sleep apnea. Nasal symptoms such as dryness, itching and congestion are common in CPAP users. Nasal and sinus saline irrigation has been shown to improve these symptoms in individuals with chronic nasal congestion and sinusitis. This is an 8 week study that investigates whether daily saline nasal and sinus irrigation reduces nasal symptoms in patients using CPAP, improves quality of life and CPAP compliance.
The purpose of this study is to evaluate the upper airway collapsibility by sleep endoscopy in different sedative levels. Propofol pump infusion will be used to achieve conscious sedation. Bispectral Index monitor will be applied to the monitor the conscious level. Two different sedative levels (BIS 65-75, 50-60) will be achieved for upper airway evaluation. The severities of upper airway obstruction will be evaluated the correlation to the disease severities. Mandible advancement will be done to evaluate the response for oral appliance.
