Simplified Clinical Pulmonary Infection Score (CPIS)
| Component | Value | Points |
|---|---|---|
| Temperature (Centigrade, degrees) | ≥ 36.5 and ≤ 38.4 | 0 |
| ≥ 38.5 and ≤ 38.9 | 1 | |
| ≥ 39.9 and ≤ 36.0 | 2 | |
| Blood leukocytes per mm3 | ≥ 4,000 and ≤ 11,000 | 0 |
| < 4,000 or > 11,000 | 1 | |
| Tracheal secretions | Few | 0 |
| Moderate | 1 | |
| Large | 2 | |
| Purulent | +1 | |
| Oxygenation (PaO2/FiO2 mm Hg) | > 240 or presence of ARDS | 0 |
| ≤ 240 and absence of ARDS | 2 | |
| Chest radiograph | No infiltrate | 0 |
| Patchy or diffuse infiltrate | 1 | |
| Localized infiltrate | 2 |
Note. ARDS = Acute respiratory distress syndrome; CPIS = Clinical Pulmonary Infection Score
