The information indicates that the patient has ventilator-associated pneumonia; ventila-tor-associated pneumonia must be suspected anytime intubation develops shortly after endotra-cheal intubation. There are many actions that can be taken to prevent its development. Current standards state that the ventilator circuit should be changed only when it is grossly contaminated.
