Pneumonia, Ventilator-Associated

The grounding supports bacterial cross-infection in hospitals as the usual cause. No additional specific etiologies are supported here.

The disease involves inflammatory lung injury occurring in the setting of pulmonary ventilation. The literature also links ventilator-associated pneumonia to acute respiratory failure syndromes and to the broader mechanisms of lung injury seen in ARDS, but the supplied grounding does not support a more specific mechanism for VAP itself.

Requiring mechanical ventilation is the defining risk context for this disease. The literature also indicates that prolonged exposure to mechanical ventilation increases risk, and that ICU-acquired infection is a common setting for occurrence.

Management is described at the level of diagnosis and drug therapy in the supplied grounding, with guideline-based care focused on diagnosis and treatment of hospital-acquired and ventilator-associated pneumonia. The literature supports microbiological confirmation when possible and treatment with antibiotic drug therapy, but does not provide specific drug classes in the supplied grounding.
