Definition sampling method originally described by Wimberley et al. based on the combination of 4 different techniques: (1) the use of fiberoptic bronchoscopy to directly sample the site of inflammation in the lung, (2) the use of a double-lumen catheter brush system with a distal occluding plug to prevent secretions from entering the catheter during passage through the bronchoscope channel, (3) the use of a brush to calibrate the volume of secretions retrieved, and (4) the use of quantitative culture techniques to aid in distinguishing between airway colonization and serious underlying infection, with a cutoff point of 103 colony-forming units (CFU)/mL for making this distinction Reference "Jean Chastre, Alain Combes, and Charles-Edouard Luyt.
