Overview
Established by the ARDS Definition Task Force in 2012, the Berlin Definition is the most current set of diagnostic criteria for ARDS.
Diagnostic criteria
The diagnosis of ARDS is made when the following diagnostic criteria are met:[1]
| Acute Respiratory Distress Syndrome – The Berlin Definition (2012) | |
|---|---|
| Timing | ❑ Within 1 week of a known clinical insult or new or worsening respiratory symptoms |
| Chest imaging a | ❑ Bilateral opacities – not fully explained by effusions, lobar/lung collapse, or nodule |
| Origin of edema | ❑ Respiratory failure not fully explained by cardiac failure or fluid overload b |
| Oxygenation c | |
|
❑ 200 mm Hg < PaO2/FIO2 ≤ 300 mmHg with PEEP or CPAP > 5 cm H2O d |
|
❑ 100 mm Hg < PaO2/FIO2 ≤ 200 mm Hg with PEEP ≥ 5 cm H2O |
|
❑ PaO2/FiO2 ≤ 100 mm Hg with PEEP ≥ 5 cm H2O |
