Berlin ARDS Severity Definition

Classify ARDS severity (mild, moderate, severe) using the 2012 Berlin Definition based on onset timing, oxygenation, PEEP requirements, bilateral infiltrates, and exclusion of cardiac origin.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Classify ARDS severity (mild, moderate, severe) using the 2012 Berlin Definition based on onset timing, oxygenation, PEEP requirements, bilateral infiltrates, and exclusion of cardiac origin

Each component has a specific meaning:

  • 2012 Berlin Definition based on onset timing — The 2012 berlin definition based on onset timing recorded for the scenario being assessed.
  • Oxygenation — The oxygenation recorded for the scenario being assessed.
  • PEEP requirements — The peep requirements recorded for the scenario being assessed.
  • Bilateral infiltrates — The bilateral infiltrates recorded for the scenario being assessed.
  • Exclusion of cardiac origin — The exclusion of cardiac origin recorded for the scenario being assessed.

Note: Interpret the berlin ards result against the thresholds and context described above.

How to Use

Enter the 2012 Berlin Definition based on onset timing, oxygenation, PEEP requirements, bilateral infiltrates, exclusion of cardiac origin for the scenario you are assessing. Classify ARDS severity (mild, moderate, severe) using the 2012 Berlin Definition based on onset timing, oxygenation, PEEP requirements, bilateral infiltrates, and exclusion of cardiac origin. Use the berlin ards result to inform your calculation.
