Active clinical trials for "Sleep Apnea, Obstructive"

The purpose of the study is to compare the relative contribution of systemic inflammation vs. Obstructive Sleep Apnea (OSA) severity (as measured by Apnea Hypopnea Index) in predicting cardiovascular and metabolic aberrations associated with mild-to-moderate obstructive sleep apnea.

The purpose of this research study is to develop a way of predicting with computers how surgery on the airway will affect night time breathing called Obstructive Sleep Apnea (OSA) in children with Down Syndrome. A research measurement for airway resistance will also be done during the clinical sleep MRI. The airway resistance measurement will take about 10 minutes and is done during sleep. The airway resistance measurement is called critical closing pressure (Pcrit).

the study aims to evaluate the accuracy correlation between subjective perception of the air flow through airways from patients and survey and/or polysomnography they spent, using a brief clinical protocol they answered with a manual therapist

The role of control of peri-pharyngeal muscle tone in the pathogenesis of obstructive sleep apnea (OSA) is obvious: pharyngeal obstruction occurs only during sleep; and pharyngeal collapse occurs in almost all healthy subjects during anesthesia. Better understanding of these control mechanisms may help identifying the central components of the pathogenesis of OSA.

Uncontrolled hypertension is associated with an increased risk of heart disease, stroke, and mortality. Obstructive sleep apnea (OSA) is common in hypertension and treatment using continuous positive airway pressure (CPAP) has been shown to effectively lower blood pressure. Despite its clinical significance, OSA remains underdiagnosed in patients with hypertension, because the current standard of care to diagnose OSA is in-laboratory polysomnography, which is inconvenient and often inaccessible for high-risk populations. An alternative to in-laboratory polysomnography is home sleep apnea testing, which has been validated against in-laboratory polysomnography and may be more convenient, accessible, and potentially cost-effective. The objective of this study is to compare home sleep apnea testing to in-laboratory polysomnography in a randomized controlled trial. The investigators will assess whether the use of home sleep apnea testing, compared to use of in-laboratory polysomnography, leads to higher rates of OSA diagnosis and treatment using CPAP, a reduction in blood pressure, improved sleep-related outcomes, and greater patient satisfaction among patients with hypertension at 6 months. The investigators will also assess whether home testing is cost-effective.

Despite the advances in the treatment of acute cardiogenic pulmonary edema (ACPE), the readmissions rates and cardiovascular events remain very high. In this context, it is possible that other potential risk factors may influence the poor prognosis of the ACPE. One of these potential candidates is Obstructive Sleep Apnea(OSA). This study was designed to evaluate the impact of OSA treatment with CPAP in consecutive patients with ACPE. The primary outcome will be to evaluate the impact of CPAP on the recurrence of ACPE in the 1-year follow-up.

Obesity is a common risk factor for the development of obstructive sleep apnea. However, not all subjects with obesity develop obstructive sleep apnea. This study will attempt to determine the mechanistic drivers between obesity and obstructive sleep apnea.

Prospective, interventional cohort study of drug-induced sleep endoscopy (DISE) to evaluate the upper airway in a cohort of obstructive sleep apnea (OSA) surgical patients. This study has investigated the reliability of this technique, demonstrating moderate-substantial interrater and test-retest reliability. This research has also compared DISE findings to those of the lateral cephalogram X-ray and examined DISE findings in individuals who have not responded to previous sleep apnea surgery. These papers have been published and available through PubMed. Additional research is ongoing, with examination of DISE findings, comparison to other evaluation techniques, and the association between DISE findings and surgical outcomes.

Comparison of the NightBalance Sleep Position Trainer (SPT) to Positive Airway Pressure (PAP) for the Treatment of Positional Obstructive Sleep Apnea (POSA). Primary Objective: Efficacy and Adherence of the SPT over 3 months of use compared to PAP for the treatment of POSA. The study is run from centers in France, the UK and Germany.

The aim of this study is to compare the preoperative and postoperative ultrasonographic measurements of patients undergoing in the prone position and the change in upper airway edema. The secondary aim of the study is to investigate the relationship between OSAS risk levels determined by the STOP-BANG score in the preoperative period of the patients participating in the study, and airway ultrasound measurements and postoperative critical respiratory events in the preoperative and postoperative period.
