Active clinical trials for "Sleep Apnea, Obstructive"

This study is a prospective, multi-center, randomized crossover of the NightBalance SPT compared to APAP for the treatment of Positional Obstructive Sleep Apnea (POSA).

Introduction: Obstructive sleep apnea (OSA) is characterized as a disorder that causes recurrent episodes of partial or complete obstruction of the upper airways during sleep. Objectives: In this way, the study will investigate the efficacy of inspiratory muscle training in improving the severity of obstructive sleep apnea and sleep quality of the research participants. Methods: The investigators will invite individuals of both sexes diagnosed with obstructive sleep apnea moderate and / or severe, arising from the Sleep Laboratory of the Hospital PROCAPE, located in Recife. This is a randomized-controlled trial, double-blind to be held in two groups: A) Individuals with OSA (moderate or severe) - Experimental Group: The components of this group hold the IMT with load of 75% of Pimáx. ( assessed weekly) for eight weeks. B) Individuals with OSA (moderate or severe) -Group control: This group will simulate training, performing no-load training for the same period the intervention group. All guidance on training and weekly evaluations will be made by the responsible for the research physiotherapist in Cardiopulmonary Physiotherapy Laboratory (LACAP - UFPE). Before and after the eight weeks, the groups will be evaluated by polysomnography, acoustic pharyngometry, tests for respiratory muscle strength (Manovacuometry) and lung function (spirometry). Expected results: Improvement of severity of OSA and sleep quality of research subjects after the completion of eight weeks of TMI when compared to the control group.

The purpose of this study is to assess the effect of continuous positive airway pressure (CPAP) on functional outcome in patients with acute stroke, the investigators conducted a sham-controlled, double-blind pilot trial during inpatient rehabilitation. Patients with acute stroke were recruited and randomly assigned to auto-titrating or sham-CPAP during their rehabilitation stay.

Obstructive sleep apnea (OSA) is a common disorder characterized by recurrent collapse of the upper airway during sleep. OSA patients have a small upper airway that is kept patent during wakefulness by a compensatory increase in upper airway (UA) dilator muscle (e.g. genioglossus) activity. At sleep onset this compensation is reduced or lost, resulting in upper airway narrowing or collapse. Previous studies of upper airway muscle training showed variable results on OSA, but so far there has not been any practical, long-term, systematic upper airway muscle training developed or studied as the treatment of OSA. In theory, strengthening the upper airway muscle with exercise training in theory helps maintain a patent airway during sleep. Therefore, investigators aim to test the hypothesis: 1) UA muscle training can improve sleep apnea in some patients with OSA, including those already receiving treatment with PAP or oral appliance therapy. 2) Muscle training is a viable therapy for a definable subset of OSA patients. Investigators hypothesize that patients with OSA who have mild or moderately compromised upper airway anatomy will benefit the most. 3)There will be a positive association between the changes in muscle function and improvement in OSA severity.

Adaptive Servo-Ventilation (ASV) treatment is routinely prescribed in France. In order to be reimbursed according to the French Social Security rules, the patient treated with an ASV needs to be examined each year. In this observational transversal single-visit study, the investigators aim to describe the clinical characteristics of patients treated with ASV and the associated device settings.

The study will evaluate the post-operative morphine-sparing effect, pain reduction, and side effects of a continuous ketamine infusion after tonsillectomy in pediatric patients.

The study aims to compare the efficacy of Nasal High Flow Therapy (NHF) with low-flow oxygen supplementation in improving postoperative intermittent desaturations. If so, this mode of therapy would provide a cost effective, relatively easy to implement, and better tolerated treatment to Continuous Positive Airway Pressure (CPAP) for oxygen stabilization.

Study objetives : The aim of this study is to assess the impact of a combined therapy treatment (physical exercise, oropharyngeal exercises and dietary recommendations) on symptoms and quality of life in patients with OSAS, as an alternative or addition to therapeutic treatment with nocturnal CPAP.

The overall goal of the study is to evaluate the safety, efficacy and therapy settings of the HGNS System for stimulating the hypoglossal nerve to help maintain an open airway in subjects with obstructive sleep apnea (OSA).

The purpose of this study is to determine whether respiratory muscle training by means of normocapnic hyperpnea leads to clinical and polysomnographical improvements in patients with mild to intermediate sleep apnea syndrome.
