Filter by:The aim of this study is to describe the effects of different levels of pressure support on ventilation-perfusion matching in patients recovering from ARDS, using electrical impedance tomography.
The goal of this observational study is to learn about the influence of mechanical ventilation on the right ventricular (RV) function. The primary focus is on methods which are routinely used to improve gas exchange in ventilated patients (positive end expiratory pressure [PEEP], inhalation of NO, prone positioning). The main questions it aims to answer are: - Effects of prone positioning, PEEP and inhalation of NO on RV-function - Are there determinants (clinical, laboratory, demographic, echocardiographic) for the right ventricular response to the above? RV-Function will be assessed with right ventricular pressure-volume loops recorded with a conductance catheter at - each PEEP-Level during titration of the best PEEP - before and every 5 minutes (for max. 45 minutes) after rotation to prone position - before and under continuous inhalation of NO (if required based on clinical grounds)
The goal of this pilot clinical trial is to test if ICU level ventilator protocols are appropriate interventions to study differences in ventilator strategies for patients with acute respiratory failure supported by VV-ECMO. The main questions it aims to answer are: - will clinicians closely follow different ICU ventilator protocols - will different ICU ventilator protocols change the way that patients are treated. Participants will be assigned to one of two ventilator protocols based on the month that they are first started on ECMO. Researchers will compare standard lung-protective ventilation to ultra-lung protective ventilation protocols to see how this changes how the ventilator is set for patients.
We intend to prospectively investigate physical and mental state (HRQOL) by means of quantitative telephone interviews after hospital discharge in patients surviving COVID-19 ARDS and ECMO therapy.
ARDS is frequent in ICU and may lead to many complications and to death. Prone position is widely used in ADRS patients and demonstrated to decrease mortality. Regarding the chest wall compliance data are missing but the theorical response is that this compliance is decreased in a prone position mainly due to anterior chest and abdomen compression in this position which are more compliant that dorsal part of the body. As well prone position could be associated with complications as pressure ulcers. Because prone position is associated with complications, air bag were developped to decrease pressure on the chest and abdomen and to decrease pressure ulcers. Then, trying to improve chest compliance in prone position and reducing the risk of pressures ulcers could be a challenge with this system in comparison with standard care.
Patients on mechanical ventilation (MV) following SARS-CoV-2 pneumonia frequently develop ventilator-associated pneumonia (VAP). The incidence of MVAP during SARS-CoV-2 infections ranges from 50 to nearly 90%. In addition, up to 80% of recurrences of VAP (a new episode, most often attributable to the same bacteria) have been described, reflecting the failure of the initial antibiotic therapy. This incidence is much higher than that described for other etiologies of acute respiratory distress syndrome (ARDS). The investigators hypothesize that during VAP, there is an alteration of the diffusion of intravenous antibiotics in the lung parenchyma in COVID-19 patients in relation to several factors characteristic of SARS-CoV-2 infection. This altered diffusion may explain the high number of recurrences of MVAP compared to non-COVID-19 patients.
Effects of APRV on right ventricular function in patients with acute respiratory distress syndrome by transthoracic echocardiography
The relationship between the presence or absence of endothelial dysfunction and changes in pulmonary perfusion will be evaluated, to then determine if there is any association between changes in the V / Q ratio and tolerance to the supine position after a prone cycle in patients with acute respiratory distress syndrome on mechanical ventilation.
Effects of airway pressure release ventilation on pulmonary ventilation, shunt and perfusion in patients with ARDS
To evaluate the safety and efficacy of intravenous (IV) administration of bone marrow mesenchymal stem cell derived extracellular vesicles (EVs), ExoFlo, versus placebo for the treatment of hospitalized patients with moderate-to-severe Acute Respiratory Distress Syndrome (ARDS).
