Acute Respiratory Distress Syndrome (ARDS) - Berlin Definition
Acute Respiratory Distress Syndrome (ARDS): Berlin Definition
In 2011 an initiative of the European Society of Intensive Care Medicine endorsed by the American Thoracic Society and the Society of Critical Care Medicine, developed the Berlin Definition of ARDS. It was subsequently empirically evaluated using patient-level meta-analysis of over 4,000 patients.

|Oxygenation (PaO2/FiO2)*||MILD: 201-300 mmHg
MODERATE: 101-200 mmHg
SEVERE: ≤ 100 mmHg
*With PEEP (or CPAP) ≥ 5 cmH2O
|ARDS Severity||Median duration of mechanical ventilation||Mortality|
