Background: Cardiopulmonary resuscitation is said to a series of measures that by artificial respiration and heart massage a person that is not breathing or has no heart rate is brought back to life. The critical maneuver can be performed without the need for any additional means and if done properly and in a timely manner will save the lives of many people from certain death. Timely and quick CPR in 4-6 minutes after cardiopulmonary arrest is of paramount importance and this time is called golden time. Methods: This is a cross-sectional, retrospective study, which is done in 2016 in Rahnemoon and Afshar hospitals with a sample of 149 people. Checklist was used to collect data. Collected data was analyzed using SPSS statistical software, T-TEST, ANOVA and descriptive tables and charts.Results: In this study, the relationship between the time of resuscitation code and CPR start with its results in Afshar and Rahnemoon hospitals was examined using T-TEST. It was shown that there is a significant correlation between the time of resuscitation code until the resuscitation start time, with patient age (P = 0.04). There is no significant relationship in term of gender, duration of resuscitation, kind of hospital, and underlying disease with result resuscitation.Conclusion: Given that, there was a significant relationship between the intervals of resuscitation code until beginning of resuscitation with age of patient, in strategic management of cardiopulmonary resuscitation, it is better to derive the attention of resuscitation team to reduction of the golden time.
