Filter by:Patients who have Obstructive Sleep Apnea (OSA) may have different Continuous Positive Airway Pressure (CPAP)when titrated with different levels of humidification. It is hypothesised that patients with ThermoSmart® technology (heated breathing tube technology) will have lower titrated pressures than those who are titrated using conventional humidification (non heated breathing tube).
This study is looking at the prevalence of sleep apnea in a wound center population. It uses both screening surveys and take home devices. Some measures of wound healing ability are being looked at as well.
This study will evaluate whether treating sleep apnea while in the hospital would help heart failure, and assist recovery from the worsening of the heart function more than the current clinical standard of waiting for treatment until the subject have left the hospital. Heart failure affects more than 2% of the US population and is the only cardiovascular disorder with rising incidence. The annual cost of CHF in 2005 was $ 27.9 billion, large percentage of which is the cost of hospitalizations for exacerbation of CHF. Half of patients with CHF have some form of sleep apnea, and most of them go undiagnosed. Patients with CHF and OSA benefit from treatment with CPAP as an outpatient. The society can benefit from developing recommendations for approaching sleep apnea in the hospitalized CHF patient, which may shorten length of stay, improve functional status of discharged patient, and reduce rehospitalizations.
We hypothesize the width air-colum of retropalatal region and tongue voulme by ultrsound through submental area is different between normal control with those with obstructive sleep apnea syndrome who was comfirmed by polysomography.
The purpose of this study is to assess the safety of ramelteon, once daily (QD), in individuals with obstructive sleep apnea.
1. CPAP compliance will be significantly higher in both the heated humidity with Thermosmart™ and the nasal steroid phases compared to the double placebo phase. 2. CPAP compliance will be comparably improved in the heated humidity with Thermosmart™ phase versus the nasal steroid phase. 3. Improvement in nasal symptoms in using CPAP will be significantly improved in both the heated humidity with Thermosmart™ and the nasal steroid phases compared to the double placebo phase, and comparable between the heated humidity with Thermosmart™ phase versus the nasal steroid phase. 4. Secondary to improvements in CPAP compliance, measures of daytime functioning and quality of life will improve in the heated humidity with Thermosmart™ versus double placebo.
Background: Upper airway muscle weakness plays an important role in the genesis of obstructive sleep apnea (OSA). Oropharyngeal exercises are derived from speech therapy consisting of isometric and isotonic exercises directed to tongue, soft palate and lateral pharyngeal wall. We hypothesized that oropharyngeal exercises will attenuate OSA severity. We will include 30 moderate OSA patients (apnea-hypopnea index (AHI), between 15 and 30 events/hour) that will randomize to 3 months of general measurements and daily nasal lavage (n=15, control) or daily oropharyngeal exercises (~30 min) plus nasal lavage (n=16). Full polysomnography, anthropometric measurements, questionnaires derived from Berlin, Epworth and Pittsburgh evaluating quantitatively (range) snoring frequency (0-4) and intensity (1-3), daytime sleepiness (0-24) and sleep quality (0-21), respectively will be performed at baseline and study end.
The purpose of this study is to compare the accuracy of EtPCO2 measurements taken with a nasal cannula using the Microcap (Oridion Capnography Inc., Needham, MA) micro-stream device and the TG-920 main-stream device (Nihon Kohden, Tokyo, Japan). Three groups of non-intubated, spontaneously breathing patients will be included: 1) lean patients without obstructive sleep apnea (OSA); 2) obese patients without OSA; and 3) obese patients diagnosed with OSA. This latter group has a higher prevalence of oral breathing. Additionally, to test the efficacy of oral guides, we propose to compare the accuracy of EtPCO2 measurements from the Microcap with two different nasal cannulas, one with (Smart CapnoLine PlusTM, Oridion Medical, Jerusalem, Israel) and one without (CapnoLineTM H, Oridion Medical) an oral guide to trap gas expired from the mouth. The TG-920 main-stream system requires its purpose-designed YG-122T cannula so that is the only one that will be tested with the Nihon-Kohden product.
This multi-site project compares compares the efficiency of a home-based portable monitoring strategy to a standard of care sleep laboratory-based strategy for the diagnosis and positive airway pressure treatment of obstructive sleep apnea in adults.
The purpose of this study is to determine the structural and functional cardiac alterations in obstructive sleep apne (OSA) independent from systemic and pulmonary arterial hypertension and their correlation to the severity of OSA.
