Active clinical trials for "Apnea"

The purpose of the study is to compare, three months after implantable cardioverter-defibrillator (ICD) or cardiac resynchronization therapy-defibrillator (CRT-D), the apnea-hypopnea index (AHI) obtained from conventional in-lab NPSG/NPG (AHIPSG) with similar indices obtained from autoscoring algorithms of the ApneaScan™, an implantable impedance-based respiration sensor (AHIAS).

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.

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 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

This study aims to evaluate the accuracy of apnea detection and automated sleep analysis by the Dreem dry-EEG headband and deep learning algorithm in comparison to the consensus of 5 sleep technologists' manual scoring of a gold-standard clinical polysomnogram (PSG) record in adults during a physician-referred overnight sleep study due to suspicion of sleep-disordered breathing.

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.

The primary purpose of this study is to demonstrate the equivalence of the new Sleep Strip OTC(TM) compared to the reference method of an in-lab, attended full-night polysomnographic (PSG) study.

This study aims to evaluate the impact of nasal continuous positive airway pressure (nCPAP) treatment on liver enzymes in patients with sleep apnea syndrome and nonalcoholic steatohepatitis. Using a cross over design, the evolution of liver enzymes will be evaluated in 40 patients during a consecutive period of 6 weeks, with and without nCPAP treatment.

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 is to compare a programme of controlled exercises therapy vs a programme of non controlled exercises therapy in patients with sleep apnea
