Ventilator-Associated Pneumonia

  • Paul Ellis Marik


Ventilator-associated pneumonia (VAP) is defined as a pneumonia which develops after 48 h of mechanical ventilation. VAP is the commonest nosocomial infection in the ICU and an important cause of morbidity. While the incidence varies according to the diagnostic criteria used and the patient population, it complicates the hospital course of about 20% of patients receiving mechanical ventilation or about five episodes per 1,000 ventilator days.1 VAP increases the number of days requiring mechanical ventilation as well as ICU and hospital length of stay; however, it is unclear if VAP independently increases mortality.
