The pathogenesis of VAP involves:
1)colonization of the aerodigestive tract.
2)aspiration of contaminated secretions into the lower airways.
3)increased use of silver-coated endotracheal tubes.
4)colonization of lower airways and lung parenchyma.

The pathogenesis of VAP most often involves colonization of the aerodigestive tract with pathogenic bacteria,aspiration of contaminated secretions into the lower airways,followed by colonization of the normally sterile lower airways and lung parenchyma with these infectious microorganisms.Recent studies have demonstrated that antimicrobial-coated ET tubes can reduce the incidence of VAP by delaying bacterial colonization and biofilm formation on the tube's inner lining.Laboratory studies have suggested that silver is an ideal coating because it is nontoxic,antimicrobial,and has anti-adhesive properties.
