Filter by:This study is to evaluate the efficacy of a new therapy (Automatic Expiratory Positive Airway Pressure with intelligent Volume Assured Pressure Support (AutoEPAP iVAPS)) designed to treat respiratory insufficiency, respiratory failure and/or nocturnal hypoventilation with upper airway obstruction. The study will be performed in two phases: In a sleep unit and in the home environment. The new therapy will be compared against two existing ventilator therapies: "Spontaneous Timed (ST) mode" and "Intelligent Volume Assured Pressure Support (iVAPS)".
The European Home Mechanical Ventilation Registry (EHMVR) will enable a thorough evaluation of HMV by documenting the characteristics of HMV patients and their treatment. This will facilitate a prospective, observational study to identify the primary indications for HMV, describe patterns of HMV use in European countries, and characterize changes in the initiation and utilization of HMV over time. The registry will target all adult individuals who have an indication for HMV. In the EHMVR, patient data from routine clinical care will be documented using an electronic case report form (eCRF). The eCRF will record: patient demographic data; diagnostic information (including primary diagnosis, 6-minute walk time, the presence of depression, and quality of life); blood gases; ventilation treatment (including type of ventilator, modes and settings, interfaces used); follow-up data (including failure rates, side effects, technical issues). An initial Pilot Phase will be launched with the aim to enrol at least 200 patients over a 6-month period to determine the feasibility of the registry. Steering committee members and their institutions will be the main participants in the Pilot Phase. After completion of the Pilot Phase, the registry will be expanded across Europe with the goal of enrolling approximately 10,000 patients over 5 years.
Investigate whether the course of an isolated nocturnal alveolar hypoventilation can predict the future occurrence of obesity-hypoventilation syndrome (OHS) in obese subjects
The purpose of this study is to determine whether breathing pattern (specifically the inspiratory time/total respiratory cycle value) has an influence over the response to the noninvasive mechanical ventilation.
This is an observational study to characterize the prevalence of Obesity Hypoventilation Syndrome in patients referred to the sleep lab.
Rationale of the "BIO-OHS" study (Prevalence of Obesity Hypoventilation Syndrome): The overall prevalence of Obesity Hypoventilation Syndrome (OHS) has never been directly assessed in the general population. Actually, this prevalence has been assessed in patients referred to sleep clinics with a potential diagnosis of sleep-disordered breathing or in patients already diagnosed with sleep apnea. The purpose of this study is to determine the prevalence of Obesity Hypoventilation syndrome in obese patients referred to clinical laboratories for regular follow-up medical analysis.
In 2012, it has announced the availability of the new ventilator (BiPAP- A40), which could offer potential advantages over fixed level pressure support, in particular, in patients with obesity hypoventilation syndrome (OHS). One of the key benefits of the BiPAP A40 is an innovative ventilation mode called AVAPS-AE, which automatically maintains airway patency while delivering the correct level of ventilation each user requires, whatever their body position or sleep stage. AVAPS-AE mode is also aimed to help the clinicians during the initial titration of therapy, while providing long term comfort and assuring therapy compliance. However, studies on the physiologic and clinical effects have not yet been performed. The aim of our singled-blind randomised multicentre controlled trial is to prospectively investigate the effects of BiPAP with the spontaneous/timed (S/T) or the AVAPS-AE ventilation mode over 8 weeks on sleep quality, ventilation pattern, gas exchange, symptoms, body composition, level of physical activity and health-related quality of life in OHS patients.
Patients with OHS are efficiently managed with long term home-based nocturnal noninvasive positive pressure ventilation (NIPPV). Several NIPPV devices offer the feature of automatically adjusting pressure support (and/or respiratory back-up rate) on the basis of a pre-determined "ideal tidal volume" or "ideal ventilation". However algorithms used to achieve these ideal targets are different among different commercialized devices and the relative efficacy from an algorithm compared to another remains unknown. The main objective is this study is to compare two commercialized NIPPV that have this option
The aim of this study is to determine whether respiratory disease exacerbations (a sudden worsening of symptoms) can be predicted by variables that are monitored by non-invasive ventilators (small machines that assist breathing) in patients requiring long term home ventilation. The investigators hypothesise that acute exacerbations of patients with respiratory disease and ventilatory failure will be predicted by changes in the respiratory variables monitored and stored by ventilators during chronic home ventilator use.
The critical nature of respiratory diseases, the continuously increasing prevalence of these conditions, and the subjective perception of patients vis-à-vis their pulmonary function and health status underscore the importance of home telemonitoring. These conditions are critical and necessitate close and regular monitoring that may be achieved at distance using telemonitoring. This study will assess a number of measures both at baseline and post-intervention from a number of domains, including Arterial Blood Gases (ABG), BiPAP-related data, chronic respiratory failure symptoms, health-related quality of life, patients satisfaction and utilization of healthcare resources.
