View clinical trials related to ARDS.
Filter by:Acute respiratory distress syndrome (ARDS) is a severe form of acute respiratory failure with mortality rates reaching as high as 35%. Management of ARDS is based on the treatment (if possible) of the underlying cause of ARDS and on invasive mechanical ventilation with positive expiratory pressure (PEEP). Another strategy of invasive ventilation, Time-Controlled Adaptative Ventilation (TCAV), is the application of specific settings to the airway pressure release ventilation (APRV) mode. TCAV is based on a prolonged time at plateau pressure, creating a phase of continuous positive pressure, associated with brief release phases allowing the elimination of carbon dioxide. In prospective and retrospective clinical reviews, as well as in experimental animal studies, TCAV has demonstrated improvements in oxygenation and lung function, with the ability to prevent ARDS. The thoracic computed tomography (CT) scan evaluates lung recruitment (re-aeration by positive pressure of non-ventilated lung territories) and the adverse effects of positive pressure on the parenchyma (hyperinflation). The objective of this study is to evaluate, with CT scans performed to assess lungs of patients with ARDS, the effects of TCAV compared to a standard volumetric controlled ventilation, by measuring alveolar recruitment and over-distension.
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.
More than 2 million patients worldwide receive heart surgery every year, majority of these surgical patients will undergo cardiopulmonary bypass. However, the incidence of postoperative acute lung injury due to cardiopulmonary bypass is still as high as 20% to 35%. According to clinical experience, the earlier lung damage is detected, the more successful the treatment will be. On the basis of traditional detection, the investigators found a new indicator, serum soluble vascular endothelial-cadherin, which are easy to obtain and have certain specificity. Importantly, they can predict postoperative acute lung injury within 1 hour after cardiac surgery. It is meaningful that this indicator can provide clinicians with early decision-making advice and immediate treatment for patients who may be at risk.
Advanced stages of the response to life-threatening infection, severe trauma, or other physiological insults often lead to exhaustion of the homeostatic mechanisms that sustain normal blood pressure and oxygenation. These syndromic presentations often meet the diagnostic criteria of sepsis and/or the acute respiratory distress syndrome (ARDS), the two most common syndromes encountered in the intensive care unit (ICU). Although critical illness syndromes, such as sepsis and ARDS, have separate clinical definitions, they often overlap clinically and share several common injury mechanisms. Moreover, there are no specific therapies for critically ill patients, and as a consequence, approximately 1 in 4 patients admitted to the ICU will not survive. The purpose of this observational study is to identify early patient biologic factors that are present at the time of ICU admission that will help diagnose critical illness syndromes earlier, identify who could benefit most from specific therapies, and enable the discovery of new treatments for syndromes such as sepsis and ARDS.
This study aim to compare the effect of Positive End Expiratory Pressure (PEEP) on ventilation/perfusion mismatch in two phenotypes of patients with moderate-to-severe Acute Respiratory Distress Syndrome (ARDS), characterized by their respiratory system elastance (Ers). Ventilation/perfusion mismatch will be assessed by Electrical Impedance Tomography (EIT).
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.
