Background: Weaning from mechanical ventilation is one of the main stages of treatment as well as applying a tool that can predict the success in weaning is very important. This study aimed to evaluate the success rate of weaning from ventilator in patients admitted at the Intensive Care Unit (ICU) using Burn’s Wean Assessment Program (BWAP) checklist.

Methods: The present analytical cross-sectional study was carried out on 100 mechanical ventilation-dependent patients connected to the ventilator for more than 72 hours. All patients were selected by simple available sampling based on purposive sampling method and examined by BWAP checklist and were weaned from ventilator by obtaining scores over 18.

Results: The total number of patients participating in the study was 100, 71 males and 29 females. There was no significant relationship between gender and success or failure of weaning process based on chi-square test (p<0.784). There was no relationship between weight and the result of weaning according to t-test. T-test showed a relationship between the number of hospitalization days with the result of weaning (P<0.001). Mann-Whitney test showed a significant relationship between age and the result of weaning according to which higher age leads to less success (p<0.001). Logistic regression indicated that age and airway could predict the result of weaning up to 78%.

Conclusion: Investigating preparation for weaning using Burn’s Scale is more useful for patients who had no prolonged hospitalization at ICU and ventilated through an endotracheal tube.
