Calc Cpis

x402 APIFailing, checked 4 h ago

Pugin 1991 clinical pulmonary infection score (CPIS, max 12) from temperature, leukocytes and band forms, tracheal secretions, PaO2/FiO2 with ARDS, chest radiograph, and tracheal-aspirate culture. Band CPIS>6 follows the 1991 derivation correlation. Not a VAP diagnosis or Singh modified CPIS.
