Introduction: Mechanical ventilation has been one of the most common forms of patients’ medical treatment in intensive care unit    and several factors affect the preparation of patients for weaning the mechanical ventilation. This study aimed at determining factors that have an impact on the duration of mechanical ventilation weaning.  
Methods: In this sectional -analytical study, 65 ICU patients who required mechanical ventilation for more than 72 hours were selected by convenience sampling. Patients with Burns Wean Assessment Program tools were studied in three shifts. Patient's age, sex, the reason for connecting them to mechanical ventilation, the level of consciousness based on the Ramsay sedation scale, and duration of mechanical ventilation were recorded before weaning.  The results were analyze through descriptive statistics and an independent t-test using SPSS 22.
 Findings: The average duration of weaning the mechanical ventilation using Burns Wean Assessment Program was 111/75±33/46.  The results, in addition, showed that confounding factors of sex (P=0/03) and Ramsay sedation scale score (P=0/0001) had a significant effect on the duration of mechanical ventilation, but age (p=0/2) and the reason for connecting them to mechanical ventilation (P=0/319) had no significant effect on the duration of mechanical ventilation.
Conclusion:  To wean the mechanical ventilation from the patients, some factors such as age and the level of consciousness – also in applying measurement devises for these variables- should be considered.
