Clinical Pulmonary Infection Score (CPIS)
Clinical Pulmonary Infection Score (Pugin 1991): temperature, leukocyte count and bands, tracheal secretions, oxygenation, chest radiograph, and tracheal-aspirate culture.

Example
- Temperature
- 39 degrees C
- Leukocyte count
- 12000 per mm^3
- Tracheal secretions
- Purulent (2)
- Oxygenation
- <= 240 mmHg and no ARDS (2)
- Chest radiograph infiltrate
- Diffuse / patchy infiltrate (1)
- Tracheal-aspirate culture
- No or light growth (0)
Result: CPIS 8/12: greater than 6 -- suggests ventilator-associated pneumonia.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Threshold
- the six components sum to 0-12; a total greater than 6 suggests ventilator-associated pneumonia.
What you enter
- Temperature
- Leukocyte count
- Band forms >= 50%
- Tracheal secretions
- Oxygenation (PaO2/FiO2)
- Chest radiograph infiltrate
- Tracheal-aspirate culture
- Same organism on Gram stain
How this is calculated
- Components
- temperature, leukocytes (+1 if band forms >= 50%), tracheal secretions, oxygenation with the ARDS exclusion, chest radiograph, and culture (+1 if the same organism on Gram stain), each 0/1/2.
