VAP

Pronunciation: vap

Also written as: VAP — Ventilator-Associated Pneumonia

Healthcare-associated pneumonia that develops 48 hours after mechanical ventilation initiation.

Full Definition

Ventilator-Associated Pneumonia (VAP) is a serious nosocomial infection that occurs in mechanically ventilated patients, typically developing 48-72 hours after intubation. In surgical critical care, VAP represents a major complication that increases mortality, length of stay, and healthcare costs. Risk factors include prolonged ventilation, aspiration, immunosuppression, and poor oral hygiene. Prevention strategies include head-of-bed elevation, oral care protocols, sedation interruption, and spontaneous breathing trials. VAP is distinguished from hospital-acquired pneumonia by the presence of mechanical ventilation and has specific diagnostic criteria involving clinical, radiographic, and microbiologic findings.

Usage

Usage note: Pronounced 'vap' as a word, commonly used in verbal communication.
