Assess the success rate of pre-Hospital cardiopulmonary resuscitation and related factors.

Backgrounds and Objectives: Cardio-pulmonary resuscitation (CPR) is performed to restore life after clinical death that is expanding in prehospital care. Therefore this study was conducted to assess the success rate of pre-Hospital cardiopulmonary resuscitation and related factors in Emergency Centers of Ardebil. Materials and Methods: This was a cross-sectional descreptive study. during the study, studied 272 cases related to cardiopulmonary resuscitation during the two years. The tool of data gathering was two-part questionnaire that first part included demographic information and second part included questions about the arrival time of the incident, the success of CPR and place of CPR.The data were analyzed using SPSS ver 16 and descriptive and analytical (chi-square) methods . Results: Statistical findings showed that the mean age of the study sample was 60/79 ± 19/74 years. the majority of participants 180 person(66/2%) were male. in 57% of cases the arrival time of emergency team to place has been between 4 to 8 minutes. cardiopulmonary resuscitation in 148 patients (54/4 %) has failed. the results indicated that there was no statistically significant relationship between cardiopulmonary resuscitation success with age, sex and time of arrival of the emergency team to place but there was statistically significant relationship between cardiopulmonary resuscitation success with basic disease. Conclusion: the present study showed that the success rate in the pre-hospital cardiopulmonary resuscitation is low, that is need to further study about related factors
