Calculate the Clinical Pulmonary Infection Score (CPIS) for a patient with the following assess-ments: 56-year-old female, post motor vehicle accident, intubated, and mechanically ventilated for 4 days
Static compliance is 42 cm H2O/L. Tracheobronchial suctioning reveals a moderate amount of yellow secretions; culture and sensitivity are pending. Breath sounds reveal bilateral lower lobe coarse rhonchi. Chest radiograph shows diffuse infiltrates. Partial pressure of oxygen in the ar-teries (PaO2) is 72 mm Hg on 40% supplemental oxygen. Patient has a temperature of 39.2° C, and white blood cell count (WBC) is 12,800 ?L.
a. CPIS = 5
b. CPIS = 6
c. CPIS = 7
d. CPIS = 8
ANS: C
Using the CPIS criteria found in Table 14-2, the score is calculated as follows: Temperature of 39.2° C = 2 points; white blood cell (WBC) is 12,800 ?L = 1 point; secretions are present and nonpurulent = 1 point; partial pressure of oxygen in the arteries/fractional inspired oxygen (PaO2/FIO2) = 72/0.4 = 180 with no acute respiratory distress syndrome (ARDS) = 2 points; chest radiograph shows diffuse infiltrates = 1 point; and compliance and saturation in the blood phase (C & S) is pending = 0 point, for a total of 7 points.
