Impact of Cardiopulmonary Resuscitation Duration on Survival of Out-of-Hospital Cardiac Arrest

Abstract

Background: Patients experiencing cardiac arrest outside medical facilities are at greater risk of death and might have negative outcomes. Cardiopulmonary resuscitation duration affects survival of such patients, which suggests that duration of CPR may be vital to patient outcomes.Objectives: The study aims to evaluate the impact of cardiopulmonary resuscitation duration on survival of patients who have suffered out-of-hospital cardiac arrest.Methods: Data were collected from emergency cases handled by a secondary hospital in industrial Jubail, Saudi Arabia, between 2015 and 2020. There were 257 out-of-hospital cardiac arrest cases, 236 of which resulted in death.Results: Bivariate analysis showed no significant association between duration of CPR, gender, and cause of death whereas there is statistically significant between duration of CPR and age (p = 0.014). Hence, the results revealed that death was more likely in elderly patients. The mean and standard deviation for the duration of emergency CPR procedures specifically in surviving patients were 26.5 ± 7.20 min, whereas in patients who died after the procedure, the mean and standard deviation for the duration of CPR were 29.6 ± 9.15 min. The mean age and standard deviation in surviving patients were found to be 38 ± 18.59 years, and 49.4 ± 23.39 years for those who died.Conclusion: Cardiopulmonary Resuscitation Duration out-of-hospital cardiac arrest does not significantly influence the patient survival in the current study hospital. Other variables may have a more significant effect.
