Filter by:The purpose of the study is to measure the negative cognitive consequences of the ventilation under pathological or experimental cortical drive to breath.
This study aims to investigate the influence of a potential leg fluid shift (LFS) in patients with chronic heart failure (CHF) and obstructive sleep apnea (OSA) or central sleep apnea (CSA).
As part of developing a relay alarm project, the aim of the study is to test a sleeper's capability to wake up via a vibrating alarm around the wrist (vibrating bracelet).
Phase 1: The European ASV Registry (short name) will investigate the use of Adaptive Servo-Ventilation in non-heart failure conditions. The purpose is to examine the effects of ASV on quality of life, daytime symptoms and sleep, to describe usage patterns of ASV with regards to patient characteristics and to document adverse events related to therapy for a therapy safety analysis. A pilot phase will enrol at least 200 patients to test the feasibility of the registry. After the pilot phase will be completed and an intermediate data analysis had been performed, the registry will be expanded over several countries across Europe with the goal of enrolling up to 800 patients over a period of 5 years. Phase 2: The READ-ASV Registry (short name) will investigate the use of Adaptive Servo-Ventilation in non-heart failure conditions. The purpose is to examine the effects of ASV on quality of life, daytime symptoms and sleep, to describe usage patterns of ASV with regards to patient characteristics and to document adverse events related to therapy for a therapy safety analysis.
Sudden unexpected death in epilepsy (SUDEP) is a tragic outcome of seizure disorders that primarily affect young adults suffering from refractory epilepsy. In this population, SUDEP incidence is estimated at 0.5%. While the mechanisms of SUDEP are not completely understood, it appears that the majority of such death occurs in the immediate aftermath of a general tonic-clonic seizure. There is currently no validated preventive treatment for SUDEP. Some evidence suggest that modulation of the serotoninergic tone, and more specifically selective serotonin recapture inhibitor (SSRI) such as fluoxetine, might prevent SUDEP. Indeed, fluoxetine prevents seizure-induced lethal central apneas in DBA/2 and DBA/1 mice, one of the few animal models of SUDEP. Furthermore, serotoninergic bulbar nuclei are known to play a major role in the control of breathing, especially during sleep and in response to repeated hypoxia. In patients with epilepsy undergoing in-hospital video-EEG monitoring, about one third of seizures are associated with decrease in SpO2 <90%, an abnormality suspected to represent a risk factor of SUDEP. In a retrospective uncontrolled study, patients treated with SSRIs displayed less frequent ictal/post-ictal hypoxemia than patients not taking SSRIs. The investigators project aimed at testing whether fluoxetine can reduce the risk of ictal/post-ictal hypoxemia by performing a double-blind, randomized, placebo-controlled trial in patients undergoing video-EEG monitoring as part of the pre-surgical evaluation of their focal drug-resistant epilepsy.
Adaptive Servo-Ventilation (ASV) treatment is routinely prescribed in France. In order to be reimbursed according to the French Social Security rules, the patient treated with an ASV needs to be examined each year. In this observational transversal single-visit study, the investigators aim to describe the clinical characteristics of patients treated with ASV and the associated device settings.
Fluid retention in the legs due to chronic heart failure (CHF) during the daytime may redistribute to neck when with supine positioning at night. A portion of the shifted fluid accumulates in the neck, and narrows the upper airway, predisposing the patient to obstructive sleep apnea (OSA) and central sleep apnea (CSA). However, the mechanism of overnight fluid shift on OSA and CSA remains unclear. The investigators pre-experiment demonstrated there may be a different mechanism of overnight fluid shift on OSA and CSA. The accumulation of water content in neck soft tissue increases neck circumference and leads to pharyngeal resistance, upper airway collapse and causes OSA. The effect of nocturnal fluid shift on CSA may be because of increasing of chemosensitivity (fluctuation of PaCO2), circulation delay and hemodynamic disordered. This study is aimed to explore the different mechanism of overnight fluid shift on OSA and CSA by comparing the changes of upper airway (inside diameter, water content, and pharyngeal resistance), PaCO2, circulation delay (lung-to-finger circulation time) and hemodynamic (loop gain).
The investigators propose to test the hypothesis that Seattle bubble nasal continuous positive airway pressure (Seattle-PAP) supports respiratory physiology in very low birth weight (VLBW) infants more effectively than standard bubble nasal continuous positive airway pressure.
The purpose of this study is to evaluate the accuracy of Somnarus diagnostic technology for diagnosis of sleep apnea in human subjects. This includes evaluation of Somnarus technology in Obstructive Sleep Apnea (OSA) and Central Sleep Apnea (CSA), including Cheyne - Stokes respiration (CSR).
The purpose of FACE study is to provide in routine practice complementary long-term data on the mortality and morbidity of Chronic Heart Failure (CHF) patients with Central Sleep Apnea eligible for Adaptative Servo-Ventilation (ASV) treatment (PaceWave, AutoSet CS; ResMed).
