Filter by:The purpose of this study is to determine whether the Transcend Auto is as effective in treating obstructive sleep apnea as another device that is already on the market.
The purpose of this protocol is to improve the current FDA-approved continuous positive pressure auto-titration algorithm, including treatment precision, residual disease detection characteristics and phenotyping with the DeVilbiss brand AutoAdjust CPAP device.
To describe the relationship between OSA and clinical Hypertension (performing ABPM), endothelial dysfunction (performing flowmetry), and its relation at the basic research (determining the β1 subunit in Peripheral Leukocytes in peripheral blood). This relation between OSA and HTA has been evaluated in basal conditions and after modifying the pathophysiological role of OSA applying treatment with positive continues pressure (CPAP) during 3 months.
The goal of this study is to assess the role of battlefield acupuncture in the reduction of pain scores status post adult tonsillectomy. Secondary goals of this study include reduction in narcotic usage, decreased nausea and vomiting, and evaluating patient factors that lend an increased risk of worsening pain or improved response with acupuncture.
Positive airway pressure (PAP) therapy is generally offered to patients with obstructive sleep apnea. The investigators suggest that beneficial effects of PAP therapy is by preventing apneas and therefore reducing cardiac and pulmonary morbidities. The investigators sought to verify this by assessing cardiac and pulmonary function during exercise.
The overall goal of this project is to determine the efficacy of a multidisciplinary treatment model for patients with Obstructive Sleep Apnea (OSA) and comorbid Insomnia. Specific Aim 1: To determine the efficacy of a treatment model combining Cognitive Behavioral Therapy (CBT) and Continued Positive Airway Pressure(CPAP) for individuals with OSA and comorbid insomnia. Specific Aim 2: To determine if there are relative benefits in the sequence of treatment initiation. Specific Aim 3: To examine the mechanisms between insomnia symptoms and CPAP adherence.
The purpose of this study in patients with obstructive sleep apnoea (OSA) and concomitant patent foramen ovale (PFO) is to assess the impact of percutaneous PFO closure on nocturnal hypoxemia and apnea/hypopnea, pulmonary and systemic artery pressure, endothelial function and arterial stiffness.
Reduced plasma nitrate (NOx) levels and increased urinary norepinephrine (U-NE) levels have been described in severe obstructive sleep apnea (OSA), and are reverted by continuous positive airway pressure (CPAP). The investigators wanted to know the effect of CPAP on these biomarkers in mild-moderate OSA.
This RCT explores the efficacy of Zonisamide (Zonegran®)on overweight/obese in patients with moderate to severe obstructive sleep apnea. Patients will be randomized to receive zonisamide, placebo or nasal continuous positive airway pressure (nCPAP) during 4 weeks. A 5 month open extension part will follow when patients in the tablet groups will all receive zonisamide. Patients in the open CPAP group will continue with CPAP treatment. Study hypothesis: Controlled pharmacological weight reduction with Zonisamide will result in elimination of OSA and OSA sequels more effectively than nCPAP due to incomplete compliance with the mechanical treatment and a lack of direct beneficial metabolic effects after nCPAP. Further it is hypothesized that zonisamide has a direct pharmacological effect on respiratory control during sleep by its carbonic anhydrase inhibitory effects and this will result in a reduction of sleep disordered breathing.
The goal of the study is to examine the possible underlying causes of sleep apnea (a disorder in which there are problems with breathing during sleep) in World Trade Center Responders. The study will look at the relationship between sleep apnea and various nose and throat conditions. Specifically, the study will look at upper airway disease (problems with the nose and throat), nasal inflammation, and nasal resistance (the amount of airflow through the nose). Subjects will have a physical exam and answer questions about nasal symptoms and sleeping problems. Nasal lavage (washing the inner nasal passages) will be performed on the subjects and markers of inflammation will be measured in the lavage fluid. Rhinomanometry (measuring the airflow through the nose) will also be performed to measure the degree of airflow obstruction. All subjects will be asked to perform in-home sleep apnea monitoring. Those subjects who are diagnosed with sleep apnea will test two treatment methods. Sleep apnea is treated by using a CPAP (continuous positive airway pressure) device. This device blows air into a mask worn by the patient during sleep. The two treatment methods that will be tested are the fixed pressure CPAP (pressure is constant during use) and CPAP-flex (pressure decreases when the subject exhales). Patients will be randomly assigned to one treatment method for one month then crossed to the other treatment method for the next month. The investigators will determine if patients with certain nasal conditions (high nasal resistance) are more likely to use CPAP-flex rather than CPAP.
