Active clinical trials for "Sleep Apnea, Obstructive"

This study has been developed in order to demonstrate the validity of the DreamKit respiratory effort signal.

It is proposed to induce in a obstructive sleep apnea syndrome patient, a hypnotic trance leading to intense muscle relaxation, capable of reproducing in the upper airways (VAS) the muscle relaxation observed in sleep, at the origin of obstructive apnea and snoring. The collapsibility type obtained, classified according to Kezirian, will allow specific management by OAM in the event of predominant anteroposterior stenosis. There are no risks fort the patient. The Drug Induce Sleep endoscopy (DISE) is a fibroscopy of upper aerodigestive tract.

The purpose of this study is to investigate the following topics: Determine the accuracy of ApneaLink Plus in separating Apneas into Obstructive Apneas, Mixed Apneas and Central Apneas. Determine the accuracy of ApneaLink Plus in scoring Hypopneas according to the 2008 guidelines of the AASM = American Academy of Sleep Medcine. Determine whether patients can start and stop the recorder and are able to attach the additional effort sensor by themselves using the patient instruction sheet

The mechanisms involved in development and maintenance of hypertension in obstructive sleep apnea are not clarified. We hypothesize that patients with obstructive sleep apnea have an abnormal level of some vasoactive hormones during apneic events during sleep.

The high prevalence (9% in men and 4% in women) of sleep apnea / hypopnea syndrome (SAHS) in adults is now well documented as well as its cardiovascular repercussions. Previous studies showed a conclusive link between SAHS and severe cardiovascular diseases such as hypertension, myocardial infarction, heart failure and stroke.Then, SAHS is a public health issue in adults. In this context, early detection of such a disease is crucial if the management is tailored to the patient, the practitioner's choice of therapy moving towards continuous positive airway pressure (CPAP) or mandibular advancement device. The detection is based on full nocturnal polysomnography or polygraphic recordings. Polysomnography remains the gold standard but it is a time consuming and costly examination. Polygraphic recording is a test that allows simplified the diagnosis of severe patients, but may not be sufficient for mild form of SAHS. Thus, the SAHS is a pathology under-diagnosed and under-treated. The validation of a technique for identifying patients most at risk to either limit the number of polysomnographic examination is requested.

In this randomised controlled cross-over study we will investigate whether intrathoracic pressure changes induced by simulated obstructive apnoea and hypopnoea trigger premature supraventricular and ventricular contractions as well as atrial fibrillation in patients with paroxysmal atrial fibrillation.

Sleep Apnea Syndrome (SAS) is a serious health issue that should be managed in order to limit its adverse health consequences. SAS is known to induce cardiovascular diseases, diabetes and depression. The prevalence of SAS is still growing with social and economic repercussion. Today, polysomnography (PSG) is the gold standard reference method for SAS diagnosis. However, it is a constraining and expensive technology. In order to improve patients' life quality, many new technologies have been developed for the SAS diagnosis. The aim of this study is to evaluate the Sunrise®, a new medical integrated solution for SAS diagnosis, in comparison with PSG. This solution consists in a chin sensor recording mandibular movements and measuring the respiratory event index (ERI) through an artificial intelligence algorithm analysis.

This study compares a volume targeted pressure support non-invasive ventilation with an automatic PEP regulation (AVAPS-AE mode) to a pressure support non-invasive ventilation (S/T mode) in patients with acute hypercapnic respiratory failure with acidosis. This study focuses on patients at risk of obstructive apneas or obesity-hypoventilation syndrom (BMI≥30 kg/m²). Half of participants (33 patients) will receive non invasive ventilation with AVAPS-AE mode, the other half will receive non-invasive ventilation with S/T mode.

The aim of the study is to find, using validated and efficient tools, a laryngopharyngeal reflux in patients receiving polysomnography for suspected obstructive sleep apnea syndrome. It is proposed to carry out simultaneously, at the Sleep Center of the Polyclinique of Poitiers (CSPP), a polysomnography, a 24-hour Restech pharyngeal pH-metry (day and night), a Peptest (in the evening and in the morning of the polysomnography), with the RSS-12 questionnaire and the RSA score.

Aim of the study To determine the exact role of hyoid bone suspension surgery in splinting lateral pharyngeal wall in the era of the lateral pharyngoplasty
