The definition of modified Clinical Pulmonary Infection Score (mCPIS)
| Items | CPIS Points | ||
| 0 | 1 | 2 | |
| Tracheal secretions | Rare | Abundant | Abundant + purulent |
| Chest X-ray infiltrates | No infiltrate | Diffused | Localised |
| Temperature (°C) | 36.5–38.4 | 38.5–38.9 | ≤36.5 or ≥39.0 |
| Leucocytes count (per mm3) | 4000–11 000 | <4000 or >11 000 | <4000 or >11 000 + band forms ≥500 |
| PaO2/FiO2,(mm Hg) | >240 or ARDS | ≤240 and no evidence of ARDS | |
| Microbiology | Negative | Positive | |
ARDS, acute respiratory distress syndrome; FiO2, fraction of inspired oxygen; PaO2, partial pressure of arterial oxygen.
