Table 1.

Berlin criteria for acute respiratory distress syndrome (ARDS) [3]. PEEP: positive end-expiratory pressure, PaO2: arterial oxygen tension, FiO2: inspiratory oxygen fraction, CT: computed tomography.

BERLIN CRITERIA
TIMING Within 1 week of a known clinical insult or new or worsening respiratory symptoms
OXYGENATION Mild: PaO2/FiO2 > 200 mmHg but ≤ 300 mmHg
Moderate: PaO2/FiO2 > 100 mmHg but ≤ 200 mmHg
Severe: PaO2/FiO2 ≤ 100 mmHg
PEEP REQUIREMENT Minimum 5 cm H2O PEEP required by invasive mechanical ventilation (noninvasive acceptable for mild ARDS)
CHEST IMAGING Bilateral opacities not fully explained by effusions, lobar/lung collapse or nodules by chest radiograph or CT
ORIGIN OF OEDEMA Respiratory failure not fully explained by cardiac failure or fluid overload (need objective assessment, such as echocardiography, to exclude hydrostatic oedema if no risk factor present)
