Active clinical trials for "Respiratory Insufficiency"

the purpose of this study to evaluate the effect of early awake PP (prone position)application on oxygenation and intubation requirement in patients with acute respiratory failure due to coronavirus disease 2019 pneumonia.

To determine whether the use of oxygen hoods as compared to conventional high-flow oxygen delivery systems, and the effects on oxygenation, mechanical ventilation and mortality rates in hypoxic patients with COVID-19.

The investigators evaluate the effects of High-flow nasal cannula (HFNC) in association with prone in patients with Covid-19 severe ARF.

Pacients who use mechanical ventilation (MV) need to pass weaning, a interruption process of ventilatory support. To predict this outcome, several scores have been developed, however, fail index in weaning and extubation remains high. The objective of this study is to evaluate the effect of ExPreS - Extubation Predictive Score - on rates of successful extubation. By a randomized clinical trial, this reseach will take place in ICUs of several hospitals. Therefore, it is expected that a difference between devices to predict extubation sucess exists and, because ExPreS is a protocol that evaluates different parameters related to many organs and systems, it presents a better capacity of predicting extubation sucess in MV patients.

Physical inactivity is the leading cause of preventable death in developed countries, ahead of smoking. It is responsible for 5.3 million (9%) of the 57 million deaths worldwide in 2008 and 10% of deaths in Europe. Encouraging regular physical activity in the general population is a public health priority. Cardiorespiratory capacity, measured during an exercise test, expressed as maximal oxygen consumption (VO2 max) or Metabolic Equivalent Task (MET) = oxygen consumption at rest [3.5 ml/kg/min], is an excellent indicator of individual exercise capacity and is increased by regular physical activity (PA). Any gain in cardiorespiratory capacity of 1 MET is accompanied by a 12% reduction in mortality whether the subjects are free of any cardiovascular pathology or have a chronic pathology, regardless of their age. As physical activity is an integral part of the management of many diseases, it seems essential to evaluate specific protocols oriented towards the maintenance or development of strength or endurance, or even mixed protocols. The PAPS 53 (Physical Activity and Health Pathway), set up in Mayenne, responds to the demand for prescription of adapted physical activity. It is a 3-month program with 2 one-hour sports sessions per week (30 minutes of endurance and 30 minutes of muscle strengthening). The National Sport and Health Strategy 2019-2024 expert group recommends better defining the characteristics of physical activity (intensity, frequency, etc.) to determine the effect (dose-response) on different at-risk populations and according to the type of pathology. Investigators proposed to study by comparison the VO2 max values obtained during the two exercise tests (at inclusion and after 3 months of physical activity program). The hypothesis is that, after completion of the PAPS program, the VO2 max value of a patient will be significantly increased. The control group is represented by the patients who have not yet followed the adapted physical activity program. The intervention group is therefore composed of the same patients. The aim is to compare the same group of eligible patients, before and after having followed the "PAPS 53" protocol

COVID-19 pandemic has presented the global health care systems with unprecedented and unexpected challenges. The clinical spectrum of COVID-19 disease varies from mild, at times asymptomatic, to severe life-threatening multiple organ dysfunction and shock. The latter group, albeit represent less than 10% of all SARS-CoV-2 infections will require ICU admission, multi-modal organ support including Extracorporeal Membrane Oxygenation (ECMO) for severe refractory cardiac and/or pulmonary failure. Prolonged mechanical ventilation is a typical indication for tracheostomy. Percutaneous tracheostomy at the bedside has several advantages over surgical tracheostomy. However, with the emerging pandemic, there is a lack of literature regarding the safety of percutaneous bedside tracheostomy for patients with COVID-19 supported by ECMO. Our study aims to describe the safety of bedside percutaneous dilatational tracheostomy of confirmed COVID-19 positive patients supported on ECMO.

Paediatric intensive care units support the complex medical needs of children with life threatening conditions. There are 20000 admissions annually within the United Kingdom and 65% require life support through a breathing machine. Chest physiotherapy is considered part of routine care for these patients. There is a small amount of evidence providing support for the effectiveness of chest physiotherapy however it has been associated with instability and adverse events. At present the risks and benefits of chest physiotherapy in ventilated children are unknown. It is important to identify which patients are likely to benefit most and in which situations chest physiotherapy may present a significant risk. Aim: To identify and understand the risk factors for instability and harmful events which may occur due to chest physiotherapy in children on intensive care. Design/Methods Work Package 1 Phase 1 - An anonymous, electronic survey will be sent to all UK physiotherapists who work in paediatric critical care. Information will be collected about physiotherapy practice, referrals, and risk factors assessed and monitored. Phase 2 - Interviews with 18-27 physiotherapists will take place. The findings from phase 1 will guide the questions. Phase 2 will provide a more in-depth understanding about physiotherapy decision making and management of risks. Work Package 2 This part of the study will quantitatively assess the effects of chest physiotherapy and identify risk factors for instability. Routinely collected data from the three intensive care units at Great Ormond Street Hospital will be used. No contact with patients/families will be required, and no change to care will occur. Data from approximately 1000 patients will be collected over one year. Health related measures (e.g. oxygen levels) will be recorded before and after chest physiotherapy.

Noninvasive ventilation (NIV) is essential to treat acute hypercapnic respiratory failure. However, facial pressure ulcers appearing during facemask-delivered noninvasive ventilation are a source of NIV failure by interface intolerance. A Philips facemask (model : AF541 SE Oro-Nasal mask) has the particularity to display two options for its positioning : a usually used "over-the-nose" positioning or an "under-the-nose" positioning that is supposed to reduce the incidence of facial pressure ulcers while keeping in the same time the qualities of a standard facemask. The goal of this controlled randomized trial is to test the hypothesis that the "under-the-nose" positioning actually reduces the incidence of facial pressure ulcers, compared to the usually used "over-the-nose" positioning. Results of this trial should lead to the proposition of a new interface strategy to prevent facial pressure ulcers and therefore to improve the tolerance of NIV via the use of facemasks displaying an "under-the-nose" positioning.

BACKGROUND: Adaptation to noninvasive ventilation (NIV) is a critical step for acceptability and efficacy of this treatment during sleep in patients with chronic respiratory failure. AIM: To study the variability of patient-ventilator interactions during the first nights after initiation to NIV. Recorded data will be analyzed in part by dedicated tools from the non-linear dynamics theory. PATIENTS AND METHODS: Patients with chronic respiratory failure at stable state and indicated to home NIV will be included. All patients will perform three polysomnographies (under spontaneous breathing at D1 and under NIV at D2 and D15 after NIV initiation). All ventilatory physiological data (pressure, flow, patient-ventilator interactions, oxygen saturation, non intentional leaks) will be recorded during sleep under NIV in the Sleep Laboratory of the Department and secondarily related to sleep architecture and quality of sleep. EXPECTED RESULTS: This study will identify objective parameters that are associated to a satisfactory adaptation to nocturnal NIV.

To compare the rapid shallow breathing index (RSBI) values, the incidence of adverse reactions, and the predictive accuracy measured under 5 different ventilator strategies in the same patient group.
