Pugin J et al. Diagnosis of ventilator-associated pneumonia by bacteriologic analysis of bronchoscopic and nonbronchoscopic blind bronchoalveolar lavage fluid. Am Rev Respir Dis. DOI: 10.1164/ajrccm/143.5_Pt_1.1055. PMID: 2024824. Scope: CPIS combines temperature, leukocytes, secretions, PaO2/FiO2, radiograph, and culture (0–2 each; total 0–12); a total above 6 is the threshold used for ventilator-associated pneumonia. (1991)
