Ventilator associated pneumonia
Ventilator-associated pneumonia (VAP) is a form of hospital acquired pneumonia (considered the commonest form 3).
It is sometimes defined as as a pneumonia occurring more than 48 hours after patients have been intubated and received mechanical ventilation 5.
It is usually suspected when the patient develops a new or progressive infiltrates on chest radiograph, leukocytosis and/or purulent tracheobronchial secretions whilst being on mechanical ventilation.
It may complicate the course of 8 to 28% of patients receiving mechanical ventilation.
Plain film features are non specific and it is impossible to differentiate from other forms of pneumonia and its the clinical setting what's useful here.
