Cardiopulmonary resuscitation affects the survival rates of such patients, which suggests that response time may be vital to patient outcomes.Objective: The aim of this study was to investigate the role of response time, whether more or less than 8 minutes, on the survival of patients who have suffered out-of-hospital cardiac arrest.Methods: Data were collected from emergency cases handled by a secondary hospital in Jubail, Saudi Arabia, between January 2017 and October 2019. There were 108 out-of-hospital cardiac arrest cases, 85 of which resulted in death.Results: Bivariate analysis showed no significant association between response time and patient outcomes; however, the odds of having a negative outcome (death) if the response time is more than 8 minutes is double the odds of dying if the response time is less than 8 minutes.Conclusion: Ambulance response time to out-of-hospital cardiac arrest does not significantly influence the patient survival rate in the current study hospital. Other variables may have a more significant effect.Keywords: cardiac arrest, patient outcomes, response time
