The most common Gram negative organisms that cause VAP in adults are:

Pseudomonas aeruginosa
Klebsiella pneumoniae
Stenotrophomonas maltophilia
Acinetobacter baumanii
As we have seen in Week 2 empiric antibiotics should have broad spectrum to cover the most likely pathogens.
Vincent’s respiratory culture results confirm:
10,000 CFU Pseudomonas aeruginosa and the following susceptibility test results:

7 Antibiotics listed with their Susceptibilities: Levofloxacin - Resistant; Cefepime - Resistant, Aztreonam - Resistant, Meropenem - Resistant, Piperacillin/Tazobactam - Resistant, Tobramycin -Susceptible, Colistin or poylmicin - Susceptible
