VAP has been recently re-defined by Centre for Disease Control and Prevention (CDC) The newly defined conditions VAC and IVAC are not much known among health care professionals. In this study, the concept of VAE (VAC, IVAC, and PP) was clarified and VAE proportion among ICU patients is calculated. Objective: This study identified the proportion of VAE among ICU patients along with the association between VAE and other variables (Specify). Methods: A series study design was used to carry out a retrospective study by reviewing 172 files of ICU patients admitted to ICU and were on ventilator for minimum of four days in the Aga Khan University Hospital in Karachi- Pakistan. The proportions of VAE were calculated and the association between VACs from one side and complications and co-morbids on the other side were calculated. Conclusion: Among 98 male 74 female participants, 23 VAC cases were detected; this means 17.85 cases per 1000 days. VAE was uncommon in our study (VAC, 13.4% and 1VAC, 8.1%). Statistics showed association between VAC event development and age of the patients along with significance relationship between mortality and VAE but, there was no association found between VAE and other variables.
