View clinical trials related to Sleep Apnea, Central.
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).
The Center for Autonomic Medicine in Pediatrics (CAMP) has built the first International CCHS (Congenital Central Hypoventilation Syndrome REDCap (Research Electronic Data Capture) Registry. This registry is an international collaboration with CCHS patients and their physicians recruited from around the world. The purpose of this IRB-approved research study is to gain a better understanding of the various clinical manifestations of CCHS with advancing age, and as related to each patient's specific PHOX2B mutation. With a better understanding of specific CCHS PHOX2B mutations and associated disease manifestations, we will be able to better anticipate healthcare needs and to provide more accurate guidelines to healthcare providers world-wide in caring for patients with CCHS. The study aims to obtain detailed phenotypic information (information about health and well-being) on patients with CCHS. Participation would require filling out a confidential survey that asks questions regarding phenotype and past medical history. Involvement in the project is completely voluntary and there is no compensation for taking part. However, this project will help us learn more about this devastating disease, with the goal of advancing treatment.
To investigate whether nHFT is an effective treatment for patients with Chronic Heart Failure (CHF) and central sleep apnea (CSA). This study is a prospective one armed uncontrolled intervention pilot study investigating 4 weeks of nHFT at home in 10 patients with CHF and 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).
Telemonitoring for Positive Airway Pressure (PAP) therapy might help to establish and maintain long-term therapy adherence and thus support the beneficial effects of PAP therapy on long-term outcomes.
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.
The aim of this study is to determine if treatment with Medical Air (21% oxygen in room air) compared to supplemental oxygen (100% oxygen) will lead to similar improvements in the central apnea-hypopnea index (CAHI) for infants with Prader-Willi Syndrome. Despite the vast amount of research investigating the cause of central sleep apnea, there remain gaps in knowledge, lending to further research efforts. The decision to compare oxygen to medical air is based on several theorized mechanisms. The first of which is the supposition that provision of medical air may act as an arousal stimulus for the hypothalamus, thereby preventing sleep disordered breathing. Secondly, the hypercapnic challenge performed by Livingston et al demonstrated a delayed hypercapneic arousal response in PWS subjects despite simultaneous hyperoxia, leading us to question if therapeutic oxygen really plays a significant role in treating CSA. Lastly, the delivery of medical air via nasal prongs may provide sufficient arousal to terminate the cycle of events leading to central apnea, as described by Urquhart et al. A deeper understanding of central sleep apnea is essential to ameliorating its adverse sequelae, which include symptoms of ADHD, impaired attention, behavioral problems, and academic difficulties.
The purpose of this study is to compare the effects of nasal and oronasal interfaces during ASV treatment on sleep efficiency and sleep architecture. Therefore, patients starting treatment with ASV, will be randomized between two groups. In the first group, patients will use a nasal interface during the first night and an oronasal interface during the second night. In the second group, patients will use an oronasal mask first and a nasal mask during the second night. The results of this trial will have major impact on future clinical practice as it would deliver prediction rules to choose the correct interface immediately.
The main goal of this French multicenter observational cohort study is to prospectively collect data assessing the impact of the Adaptative Servo-Ventilation treatment on the quality of sleep of patients with central or combined sleep apnea syndrome (SAS) out of Heart Failure (HF) with altered ejection fraction, with a predominant central SAS.
