Pneumonia that develops within 48 hours after intubation?
Risk factor for MDR: Hospitalization for greater than 2 days in the past _____ days
Risk factor for MDR: ABX use in the past ______ days
Risk factors for MDR pathogens is the main risk factor for which type of pneumonia?
For diagnosis: Criteria #1
For diagnosis: Fever greater than _____˚F
For diagnosis: Leukocytosis or _______
For diagnosis: _________ pulmonary secretions
A score greater than ________ on the Clinical Pulmonary Infection Score (CPIS) is suggestive of pneumonia?
Endotracheal aspirate threshold = 10^___ cfu/mL
Bronchoalveolar lavage threshold = 10^___ cfu/mL
