Extra Vascular Lung Water and Pulmonary Permeability in Critically Ill Patients With SARS-CoV-2...
COVID-19Pneumonia1 moreAcute respiratory distress syndrome (ARDS) is a syndromic definition of an acute lung injury with alteration of biomechanics (lower respiratory system compliance) mostly associated with increased lesional edema. Increase in Pulmonary Vascular Permeability Index (PVPI) accompanied with accumulation of excess Extravascular Lung Water (EVLW) is the hallmark of ARDS. In routine clinical practice, the investigators measure the EVLW and PVPI in ARDS patients, as suggested by expert's recommendations, using a transpulmonary thermodilution (TPTD) technique. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a newly recognized illness that has spread rapidly throughout Wuhan (Hubei province) to other provinces in China and around the world. Most critically ill patients with SARS-CoV-2 will present the criteria for the definition of ARDS. However, many of these patients have a particular form of ARDS with severe hypoxemia often associated with near normal respiratory system compliance. This combination is almost never seen in severe ARDS. Thus other mechanisms (including probably vascular mechanisms), that are still poorly described, have to be involved in SARS-CoV-2. EVLW and PVPI have never been assessed in SARS-CoV-2 mechanically ventilated patients. The aim of this study is to evaluate these two parameters in order to best characterize and understand the mechanisms related to SARS-CoV-2. Based on observation of several cases in intensive care units (ICU), the investigators hypothesize that there are following different SARS-CoV-2 patterns: Nearly normal compliance, low lung recruitability, normal EVLW and low PVPI. Low compliance due to increased edema, high lung recruitability, high EVLW and high PVPI.
Wide Scale Monitoring for Acute Respiratory Infection Using a Mobile-Based Study Platform
Covid19Influenza3 moreThis is a prospective observational study using a mobile study platform (app) that is designed for use on Android phones. Study participants will provide baseline demographic and medical information and report symptoms of respiratory infection on a weekly basis using the app. Participants will also report use of prevention techniques on the weekly survey. Mobility data will be collected passively using the sensors on the participant's smartphone, if the participant has granted the proper device permissions. The overall goals of the study are to track spread of coronavirus-like illness (CLI), influenza-like illness (ILI) and non-specific respiratory illness (NSRI) on a near-real time basis and identify specific behaviors associated with an increased or decreased risk of developing these conditions.
Impact of Different Modes of Noninvasive Ventilation on Regional Oximetry and Hemodynamics in Premature...
Respiratory Distress SyndromeThe purpose of this study is to examine the blood flow and the delivery of oxygen to the brain and gut in preterm babies while they are supported with two modes of breathing machine and compare these two methods to see if one allows for better blood flow to the brain and gut.
Practice of Ventilation in Critically Ill Patients Without ARDS
Mechanical VentilationThe purpose of this international, multicenter study is to determine ventilation practice and outcomes of intubated and ventilated intensive care unit (ICU) patients. Ventilation characteristics and outcomes will be compared between patients without the acute respiratory distress syndrome (ARDS), patients at risk for ARDS, and patients with mild, moderate or severe ARDS. Participating centres worldwide will include adult patients undergoing mechanical ventilation in the ICU during a 7-day period. Patients data will be collected during the first 7 days in the ICU, or until ICU discharge. Follow up is until day 90. Primary endpoint is the tidal volume size used during mechanical ventilation. Secondary endpoints are development of ARDS in patients without ARDS at the onset of mechanical ventilation, worsening of ARDS in patients with ARDS at the onset of mechanical ventilation, pulmonary infection, other pulmonary complications, need for tracheostomy, extra-pulmonary complications, duration of ventilation, length of ICU and hospital stay, and ICU, hospital and 90-day mortality.
Energy Load in Patients With Acute Respiratory Distress Syndrome (ARDS)
Acute Respiratory Distress Syndrome (ARDS)The investigator would assess if there is an incremental energy load during mechanical ventilation in Acute Respiratory Distress Syndrome (ARDS) patients.
The Role of Circulating Soluble CD74 in Acute Lung Injury
Acute Lung InjuryAcute Respiratory Distress SyndromeEfforts to identify circulating factors that predict severity of acute lung injury/acute respiratory distress syndrome(ALI/ARDS) patients is unrevealing. The primary purpose of this study is to verify our hypothesis that soluble CD74 might be a potential novel ALI/ARDS biomarker.
Effects of PEEP and FIO2 in ALI and ARDS
Acute Respiratory Distress SyndromeAcute Lung Injury1 moreCurrent American-European Consensus Conference (AECC) definitions for ALI and ARDS are inadequate for inclusion into clinical trials due to the lack of standardization for measuring the oxygenation defect. We questioned whether an early assessment of oxygenation on specific ventilator settings would identify patients with established ARDS (persisting over 24h).
Timing and Intensity of the Exposures and Attributable Burden of Acute Lung Injury
Acute Lung InjuryAcute Respiratory Distress SyndromeThe purpose of the study is to identify the patients at high risk of developing Acute Lung Injury (ALI) at the time of hospital admission, and before intensive care unit admission. Aim 1- To validate the prediction model (Lung Injury Prediction Score) in a population based sample of hospitalized patients. Aim 2- To determine the significance of health-care related ALI risk modifiers in a population based sample. Aim 3- To compare the short and long term outcomes between patients at high risk who do, and do not develop ALI.

Ventilation's Parameters Applied in Emergency Medicine. A Prospective Observational Study
Mechanical VentilationAcute Respiratory Distress Syndrome2 moreTo prospectively assess the mechanical ventilation management when its provided by Emergency Physicians in French Hospital, and to assess complications and outcome of these patients. The study could be measure the proportion of patients developing an Acute Respiratory Failure Distress after a take care of by French Emergency Departments.
