Active clinical trials for "Respiratory Insufficiency"

The effectiveness of NIV is clearly demonstrated but no recent studies describe the prescription based on clinical data and the conditions of using NIV at home according the various respiratory diseases. The investigators' purpose is that a better knowledge of NIV practices could improve both the quality to support patients at home and the efficacy of the treatment. The main objective of this study is to analyze the clinical data justifying the prescription of NIV advice according respiratory disease. The secondary objectives are to study comorbidities, treatment failures, survival rate during the study period.

A randomized, double-Blind, placebo-controlled trial aimed to investigate the safety and efficacy of sivelestat on treating adult patients with COVID-19-related acute respiratory distress syndrome (ARDS)

Despite almost universal usage of supplemental oxygen therapy in patients presenting in the emergency department with traumatic brain injury (TBI), optimal oxygen levels are unclear. The investigators propose a pilot multi-center randomized controlled trial to test the hypothesis that maintaining intermediate normal as opposed to high normal oxygen levels in patients presenting in the emergency department with TBI is feasible, and to obtain preliminary data on the efficacy of the two approaches to oxygen therapy. The aim is that the investigators produce pilot data, which could inform the design of potential subsequent larger clinical trials.

Current evidence suggests a mechanistic and physiological rationale for the use of high flow nasal cannula (HFNC) in acute respiratory hypoxemic failure (AHRF) based on physiological studies in airway models, healthy volunteers and patients with Chronic Obstructive Respiratory Disease (COPD). This is supported by observational studies in patients with AHRF with reductions in a range of respiratory and other physiological parameters. Observational studies also suggest similar intubation rates and lower failure rates with HFNC when compared to non-invasive ventilation (NIV) with improved patient acceptance and tolerance for HFNC. The role of HFNC is less clear in acute hypercapnic respiratory failure. Although non-invasive ventilation is the recommended treatment, it is associated with discomfort, and a significant proportion (up to 25% in some reports) cannot tolerate non-invasive ventilation. Observational reports and limited data from randomized controlled trials suggests that HFNC is effective in treating patients with hypercapnic respiratory failure. We designed this trial to assess whether early application of HFNC in patients with non-severe hypercapnic respiratory failure can correct barometric abnormalities, and prevent progression to non-invasive ventilation or tracheal intubation and mechanical ventilation.

There is a drug-related death crisis in Scotland. The majority of these deaths have involved the misuse of opiates (e.g. heroin) and benzodiazepines (e.g. valium) which cause an individual to stop breathing. The Advanced Respiratory Monitoring Events in Drug Toxicity (ARM-ED) study is a study investigating whether a wearable sensor can help detect problems with breathing in patients who have had drugs or medications that may cause this effect. The study will span a year and will study two groups of patients - those who attend with actual or expected respiratory depression secondary to acute drug toxicity and individuals who have undergone procedural sedation and analgaesia in the Emergency Department.

ARDS is an acutely induced respiratory failure characterized by the appearance of bilateral alveolar opacities on imaging and hypoxemia Etiologies are divided into two classes: pulmonary, including all infectious pathologies, aspiration pneumonia, and drowning, and extra-pulmonary, induced by sepsis or acute pancreatitis. The mortality rate of ARDS remains high in unselected patient populations Among strategies that have proven beneficial in terms of patient outcome, prone positioning (PP) is associated with the greatest impact in terms of reduction in mortality. PP is currently recommended in the European guidelines for ARDS associated with a PaO2/FiO2 ratio < 150 mmHg in patients in whom ventilatory settings have been optimized beforehand, The failure of early PP studies to demonstrate a survival benefit in ARDS was attributed to insufficient session duration. The PROSEVA study was the first to demonstrate that a PP duration of 17 h is associated with a reduction in mortality During the COVID-19 pandemic, several centers have reported the implementation of longer PP sessions. Two strategies have emerged from these studies. In one case, the patient was left in the prone position until the criteria for stopping PP were met. Thus, the PP/supine position alternation was completely suppressed. In another published strategy, PP sessions were maintained for a period covering two nights. Furthermore, in a multicenter retrospective study, PP sessions were maintained until clinical improvement was associated with reduced mortality. In this study of 263 patients, the median duration of PP in the extended duration group was 40 h, and 75% of the sessions lasted 48 h or less. Using a propensity score, the authors showed that patients treated with an extended PP duration had a lower 3-month mortality rate than patients in the standard duration group . This protocol was also associated with a 29% cumulative incidence of pressure sores, similar to the 25% cumulative incidence reported in the PROSEVA study Other data published on pressure sores and PP of duration > 24 hours are also reassuring. Finally, a recent review recently reported that an extended PP session of > 24 h had also been used before the COVID-19 pandemic. PP sessions had a median duration of 47-78 hours and were applied mainly to ARDS secondary to community-acquired pneumonia. All pre-COVID studies were retrospective, monocentric, without a control group.

This study will determine if NIV using the Vela investigational mask with expiratory washout of the upper airway more effectively reduces respiratory rate in acute patients with hypercapnic respiratory failure. Patients admitted to hospital with acute respiratory failure (ARF) will be assessed for hypercapnic ARF by normal hospital protocols. Patients requiring noninvasive ventilation (NIV) will be set up on NIV as prescribed per standard of care. Enrollment onto the investigation will occur after the patient has been allowed to stabilize on NIV . Patients that meet the inclusion/exclusion criteria will be approached for consent. Investigation participants will receive two masks in random order; NIV for one hour with the investigational mask (Vela) NIV for one hour with the standard mask (Nivairo). Participants will have their physiological respiratory parameters recorded.

A single center, observational, prospective study to improve knowledge about non-invasive ventilation, obtaining data about compliance, efficacy, imaging in patients who already receive non-invasive ventilation as standard of care.

A reduction of peripheral oxygen saturation (SpO2) commonly occurs during bronchoscopy and may be associated with both respiratory and cardiac adverse events. The type of breathing assistance that should be delivered to patients, in order to treat and/or to prevent acute respiratory failure, during or after bronchoscopy, is not universally standardized; studies comparing the impact of different respiratory supports on patient's outcome and on hospital resource use are very few. the risk of respiratory failure rises according to the type of procedure (i.e., increased risk with broncho-alveolar lavage and trans-bronchial lung biopsy) and to the use of sedative drugs. Conventional oxygen therapy with nasal cannula, continuous positive airway pressure and non-invasive ventilation are commonly applied during endoscopic procedures. High flow oxygen therapy (HFOT) is a relatively novel device, still under-used in the context of interventional pulmonology, providing an humidified air-oxygen blend up to 60 L/min. HFOT has been reported to be effective for the treatment of both hypoxemic and hypercapnic respiratory failure. The investigators hypothesize that HFOT could be feasible and safe in patients undergoing bronchoscopy under moderate sedation, affected by or at risk of hypoxemic and/or hypercapnic respiratory failure.

The goal of this observational study is to establish an intelligent early warning system for acute and critical complications of the respiratory system such as pulmonary embolism and respiratory failure. Based on the electronic case database of the biomedical big data research center and the clinical real-world vital signs big data collected by wearable devices, the hybrid model architecture with multi-channel gated circulation unit neural network and deep neural network as the core is adopted, Mining the time series trends of multiple vital signs and their linkage change characteristics, integrating the structural nursing observation, laboratory examination and other multimodal clinical information to establish a prediction model, so as to improve patient safety, and lay the foundation for the later establishment of a higher-level and more comprehensive artificial intelligence clinical nursing decision support system. Issues addressed in this study The big data of vital signs of patients collected in real-time by wearable devices were used to explore the internal relationship between the change trend of vital signs and postoperative complications (mainly including infection complications, respiratory failure, pulmonary embolism, cardiac arrest). Supplemented with necessary nursing observation, laboratory examination and other information, and use machine learning technology to build a prediction model of postoperative complications. Develop the prediction model into software to provide auxiliary decision support for clinical medical staff, and lay the foundation for the later establishment of a higher-level and more comprehensive AI clinical decision support system.
