To study the risk factors and pathogens of ventilator-associated pneumonia (VAP) and to discuss the treatment and preventive measures. Methods: The clinical data of 28 cases of VAP and the results of bacterial culture of respiratory secretions were analyzed. Results: Coma, application of MV time greater than 7d is a risk factor for VAP; Pseudomonas aeruginosa, Acinetobacter baumannii and Escherichia coli are the main pathogens of VAP. Conclusion: According to the risk factors of VAP and the main pathogenic bacteria, the mechanism of its occurrence is analyzed and the treatment and preventive measures are put forward
