JAMA. 2012;307:2526-2533. The acute respiratory distress syndrome (ARDS) was originally defined as a clinical condition in 1967, although it had been recognized for years prior in soldiers dying of wartime injuries. But now it is consistently known as acute respiratory distress syndrome (ARDS), because it is a well-known entity in pediatric population since the first description in 1967. In the last 5 decades, our knowledge and experience has grown substantially and the definition continues to evolve.

Acute respiratory distress syndrome (ARDS) is a medical condition occurring in critically ill patients characterized by widespread inflammation in the lungs. ARDS is not a particular disease, rather it is a clinical phenotype which may be triggered by various pathologies such as trauma, pneumonia and sepsis. In effect, ARDS results in impaired gas exchange within the lungs at the level of the microscopic alveoli. The syndrome is associated with a high mortality rate between 20 and 50%. The mortality rate with ARDS varies widely based on severity, the patient's age, and the presence of other underlying medical conditions. Acute Respiratory Distress Syndrome: the Berlin Definition. Summary. The acute respiratory distress syndrome (ARDS) was originally defined as a clinical condition in 1967, although it had been recognized for years prior in soldiers dying of wartime injuries. Various attempts to better define the condition resulted in the American-European Consensus Conference (AECC) definition, published in 1994. Changes from the 1994 AECC definition. the term acute lung injury was abandoned. measurement of the PaO2/FIO2 ratio was changed to require a specific minimum amount of PEEP. 3 categories of ARDS were proposed (mild, moderate, and severe) based on the PaO2/FIO2 ratio. Radiographic criteria were changed to improve interrater reliability. • Meet the New ARDS: Expert panel announces new definition, severity classes (JAMA): • The panel’s findings, endorsed by the European Society of Intensive Care Medicine, the American. Thoracic Society (ATS) and the Society of Critical Care Medicine (SCCM), emerged from meetings in. Acute lung injury (ALI) Ratio Calculator. Acute lung injury (ALI) is a diffuse heterogeneous lung injury characterized by hypoxemia, non cardiogenic pulmonary edema, low lung compliance and widespread capillary leakage.
