Active clinical trials for "Sleep Apnea, Obstructive"

Sustainable Methods, Algorithms, and Research Tools for Delivering Optimal Care Study (SMART DOCS) was designed to develop and evaluate a new approach (patient-centered outcomes and coordinated-care management [PCCM]) for the diagnosis and treatment of sleep disorders. Specialized and pertinent information and resources regarding sleep disorder management were developed and made available through an online portal, allowing patients to make informed health care decisions, and providers to assist patients in achieving what they feel are the most important goals regarding their care. Half of participants were randomized into the conventional diagnosis and treatment (CONV) arm and the other half into the patient-centered outcomes and coordinated-care management (PCCM) arm. Validated objective and subjective assessment measures were administered at intervals throughout a 13 month participation period in both the CONV and PCCM arms to determine whether the new PCCM approach for sleep medicine results in increased patient satisfaction, quality of care, and improved health outcomes. Qualifying participants were 18 years of age or older and presenting with a new sleep disorder. Patients received no monetary compensation.

Our group has recently found that the choice of positive airway pressure mask can significantly affect the pressure required to adequately treat sleep disordered breathing. The goal of this study is to visualize the upper airway in the retropalatal and retroglossal region while using both oronasal and nasal masks with CPAP in order to investigate differences in upper airway dynamics that may occur between these two mask types.

Driving simulator programmes are used under a wide range of conditions, and a correlation of driving performance and real accident risks in patients with obstructive sleep apnoea syndrome(OSAS)could be shown. The most frequently used driving simulator is the Divided Attention Steering Simulator (DASS) of Stowood Scientific Instruments Ltd. (SSI). Until today there are no reference levels with regards to sex and age in existence. To define the boundaries of normality age and sex reference values are to be generated and compared to values of patients with OSAS. 50 male and 50 female healthy subjects (10 of each age decade between 20 and 70 years) will perform the DASS for 30 minutes. In the other arm 100 OSAS Patients will perform the test as well. A better differentiation of pathologic driving performance and response times of OSAS patients should be possible with new reference levels.

BACKGROUND AND AIMS Continuous positive airway pressure (CPAP) is an effective therapy to treat sleep apnea. Sleep apnea is a condition where the airways collapse when the patient is asleep. CPAP treats sleep apnea by delivering an air pressure to the airways, splinting the airways open. CPAP is a device that sits besides the bed and is applied to the patient using a face mask. The development of new CPAP masks is an on-going focus at ResMed Ltd in a bid to improve comfort and user compliance. ResMed are developing a new mask and investigations are required to evaluate mask performance over time. ResMed Ltd design and manufacturer CPAP masks. The revision and development of masks is an on-going focus of the company in a bid to improve usability and patient compliance while maintaining optimum treatment. ResMed is developing a new mask. Investigations are therefore required to determine how much matter is built-up on the mask over time and to evaluate mask performance (including comfort and seal) and efficacy. AIMS The aims of the study are: To measure and compare the change in the abundance of microbes on the new mask over a period of 8 weeks To measure and compare the change in comfort, seal, stability, efficacy, leak and user compliance of this new mask over a period of 8 weeks To measure and compare the change in comfort, seal, stability, efficacy, leak and user compliance of this new mask versus an available mask It is hypothesised that: The new mask acquires microbes from the user but there is no difference in the abundance of microorganisms between 2 and 8 weeks. The new mask maintains the same degree of comfort, seal, stability, efficacy, leak and compliance between 2 and 8 weeks. Compared to the existing mask, the new mask provides a higher degree of comfort, seal and stability and improves user compliance. The new mask also maintains efficacy, and maintains or reduces leak compared to the current masks.

The purpose of this study is to find out whether taking eszopiclone (Lunesta) changes the breathing effort required to briefly wake people with obstructive sleep apnea from sleep (respiratory arousal threshold). We would like to see if taking eszopiclone can reduce the severity of obstructive sleep apnea in some people (those that have a low respiratory arousal threshold; i.e. wake up easily to respiratory stimuli).

The purpose of this research is to find out how a nasal spray (fluticasone furoate), sometimes given to children with obstructive sleep apnea syndrome (OSAS), works on certain cells within a child's adenoids. We hypothesize that intranasal steroids lead to an upregulation of T regulatory cells in the adenoid tissues of children with OSAS. This will result in a local reduction in inflammation and edema explaining the improvement in OSAS.

The purpose of this study is to assess the efficacy of Eszopiclone in improving short and intermediate-term compliance with continuous positive airway pressure (CPAP) in patients newly diagnosed with obstructive sleep apnea (OSA).

Assessment of the performance of the Salt Lake mask system acting as a patient interface in the provision of PAP therapy. This study will assess the suitability of this mask system in its current form for use.

The study has been designed to assess the effect of cyclooxygenase inhibition on blood pressure, cerebral blood flow, ventilation and renal hemodynamics following chronic intermittent hypoxia exposure.

Context: Obstructive sleep apnea syndrome (OSAS) is associated with cardiovascular morbidity. Recurrent episodes of occlusion of upper airways during sleep result in hormonal changes that may predispose to high cardiovascular risk.These risks can rapidly be reduced by effective nasal continuous positive airway pressure (nCPAP) therapy Objective: To evaluate hypothalamic pituitary adrenal axis, insulin resistance, blood pressure values and adipokines in severe obese patients with and without OSAS and to determine if continuous positive airway pressure therapy (nCPAP) influenced responses.
