Figure 1 Schematic diagram of an intubated patient with an ETT in the trachea, emphasizing the high concentrations of bacteria in the oropharynx and the presence of bacteria above the ETT cuff that can be removed by CASS. Note the number of bacteria isolated by semiquantiative endotracheal aspiration (SQ-ETA) and quantitative endotracheal aspiration (Q-ETA) aspirates needed for a microbiological diagnosis of VAT and VAP. Also shown are the quantitative levels of bacteria needed for the microbiological diagnosis of VAP by distal lung samples obtained by BAL or protected specimen brush. NG = nasogastric (tube).
