Clinical takeaway

Onset within 1 week, bilateral opacities, non-cardiogenic, PEEP ≥5.

When to use

ARDS diagnosis and severity grading.

How it works

On PEEP/CPAP ≥5 cmH₂O: mild 200<P/F≤300, moderate 100<P/F≤200, severe P/F≤100.

Key points

  • Onset within 1 week, bilateral opacities, non-cardiogenic, PEEP ≥5.
  • Graded by P/F.
  • The 2024 global definition adds SpO₂/FiO₂ and ultrasound.

Worked calculation

The values below come from this tool's own example placeholders and are computed server-side with the formula shown on this page, so the arithmetic can be checked quickly. It demonstrates how to substitute values only — it is not clinical advice and not a real case.

PaO₂/FiO₂ (with PEEP/CPAP ≥ 5)150 mmHg

→ClassModerate ARDS

  • P/F：150 mmHg
  • Mortality (Berlin 2012 pooled)：32%
  • 2024 global definition：The 2024 global definition (Matthay) adds high-flow oxygen ≥30 L/min, SpO₂/FiO₂ ≤315 and ultrasound imaging; this tool uses Berlin 2012.

FAQ

Frequently asked questions

Does Berlin ARDS Severity Classification upload patient data? Where is it calculated?
Calculation runs locally in the browser; inputs and results are not uploaded. For licensed clinicians only; interpret with history, investigations and local protocols — not a diagnosis or prescription.
How is Berlin ARDS Severity Classification calculated in practice? Can you show a worked example?
Inputs: PaO₂/FiO₂ (with PEEP/CPAP ≥ 5) 150 mmHg → Result: Class Moderate ARDS（P/F: 150 mmHg, Mortality (Berlin 2012 pooled): 32%, 2024 global definition: The 2024 global definition (Matthay) adds high-flow oxygen ≥30 L/min, SpO₂/FiO₂ ≤315 and ultrasound imaging; this tool uses Berlin 2012.）
