📋 Case data
- Oxygenation gradeModerate–severe (P/F ≤200, especially <150)
Data is taken from this pathway's reviewed node text. Work through the pathway step by step.
Step 1 / 1 · Oxygenation grade
Meets the Berlin definition? Oxygenation grade (PEEP ≥5)?
💡 Berlin definition: 1) within 1 week of a known insult / new or worsening respiratory symptoms 2) bilateral infiltrates not fully explained by effusion/atelectasis/nodules 3) respiratory failure not fully explained by heart failure/fluid overload (echo to exclude cardiogenic if needed) 4) oxygenation (PEEP/CPAP ≥5): mild P/F 200–300, moderate 100–200, severe ≤100. Causes: pneumonia/sepsis (most common), aspiration, trauma, transfusion, pancreatitis.
