Abstract
Background. Cardiopulmonary resuscitation (CPR) is the most critical life-saving measure, especially when performed immediately after cardiac arrest. This study aimed to investigate the factors affecting the success of CPR in Maragheh city in 2023-2024.
Methods. This retrospective descriptive-analytical study was conducted on 300 CPR cases. Samples were randomly selected proportionally from each hospital. Categorical data were described using frequency and percentage, and continuous data were described using mean and standard deviation. Associations between variables were assessed using Chi-square test, Fisher’s exact test, Mann–Whitney U test, and logistic regression.
Results. The study population included 197 men (65.7%) and 103 women (34.3%) with a mean age of 61.4±22.1 years. Return of spontaneous circulation (ROSC) was achieved in 39 patients (13%). Based on the results of logistic regression analysis, there was a statistically significant association between the duration of CPR and clinical outcomes. No significant association was observed between CPR success and other demographic or clinical variables.
Conclusion. CPR outcomes are influenced by various factors. A significant relationship was observed between CPR duration and its success, while other demographic and clinical variables showed no significant association.
Practical Implications. Based on the findings of the study, implementing structured timekeeping protocols to reduce CPR duration, developing rhythm-specific response protocols with emphasis on shockable rhythms, and providing specialized training for managing non-shockable rhythms (particularly asystole, which accounted for 65.1% of cases) represent targeted strategies for improving the success rate of CPR.
