Nosocomial pneumonia is the most deadly of all hospital-acquired infections. Ventilator-associated pneumonia (VAP) refers to a subset of nosocomial pneumonia that develops in patients receiving mechanical ventilation. The rate of VAP has been estimated to be increased 6- to 20-fold over the rate for nosocomial pneumonia in patients not receiving mechanical ventilation. 17 Celis R.A., Torres A., Gatell J.M. , y al.

Haga clic aquí para ir a la sección de Referencias Because of the high risk for pneumonia and attendant mortality, many studies have been done to determine the best measures for preventing pneumonia in patients receiving mechanical ventilation. This article reviews preventive measures, the organisms associated with VAP, and issues related to selecting appropriate antibiotic therapy.
