Table 1 CPIS score parameters (Schurink et al., 2004)

1. Body temperature ≥ 36.5 or ≤ 38.4 = 0 point ≥ 38.5 or ≤ 38.9 = 1 point ≥ 39 or < 36.5 = 2 points 2. Total leucocytic count ≥ 4000 or ≤ 11.000 = 0 point < 4000 or > 11.000 = 1 point Rod form ≥ 50% = add 1 point 3. Tracheal secretion Tracheal secretion (−) = 0 point Tracheal secretion with less purulence = 1 point Abundant purulent secretion = 2 points 4. Oxygenization Pa02/Fi02, mmHg >240 or ARDS (ARDS: Pa02/Fi02 < 200, Pa02/Fi02 < 200, PAWP ≤ 18 mmHg and bilateral acute infiltration) = 0 point Pa02/Fi02, mmHg ≤ 240 or ARDS = 2 points |
5. Pulmonary infiltration in chest X-ray No infiltration = 0 point Diffuse infiltration = 1 point Localized infiltration = 1 point 6. Progression in pulmonary infiltration Radiographic progression (−) = 0 point Radiographic progression (+) (after the exclusion of HF and ARDS) = 2 points 7. Pathogenic bacteria in tracheal aspirate culture No or few pathogenic bacteria = 0 point Moderate or high levels of pathogenic bacteria = 1 point Pathogenic bacteria to be seen in Gram staining, add 1 point |
