Also written as: VAP — ventilator-associated pneumonia
Nosocomial pneumonia occurring in mechanically ventilated patients 48 hours or more after intubation.
Full Definition
Ventilator-associated pneumonia (VAP) is a type of healthcare-associated pneumonia that develops in patients who have been mechanically ventilated for at least 48 hours. VAP results from bacterial colonization of the endotracheal tube and subsequent aspiration of contaminated secretions into the lower respiratory tract. Prevention strategies include elevation of the head of bed, oral care with chlorhexidine, subglottic secretion drainage, and daily sedation vacations. Respiratory therapists play a key role in VAP prevention through proper ventilator circuit management and adherence to evidence-based protocols.
Usage
Usage note: Can be abbreviated as VAP in clinical contexts; hyphenate when spelled out.
