Key Factors Determining the Success of Cardiopulmonary Resuscitation: A Multi-center Study Investigating Survival Rates and Predictors.

Introduction Cardiac arrest can be fatal if not addressed quickly, and cardiopulmonary resuscitation (CPR) is a critical intervention to sustain life in cases of cardiac arrest. Multiple factors affect the mortality of patients who had cardiac arrest and subsequently CPR, such as the timing at which CPR is started. Due to the scarcity of local evidence regarding cardiac arrest in Saudi Arabia, this study aims to identify the predictors of CPR success and survival rate, namely, return of spontaneous circulation (ROSC).
