Abstract

Background: Cardio-pulmonary resuscitation (CPR) is a critical life-saving intervention in cases of sudden cardiac arrest or respiratory failure. Despite its widespread use, survival rates after cardiac arrest vary significantly across different populations, largely influenced by factors such as healthcare infrastructure, resource availability, and training, especially when comparing developed and developing countries. Objectives: The aim of our study is to assess the effect of duration of cardiopulmonary resuscitation (CPR) and initial cardiac rhythm in predicting the return of spontaneous circulation (ROSC) in adults of in-hospital cardiac arrest. Methods: We conducted retrospective clinical record audit of 94 adult patients (age ≥18 years) between April 2025 and May 2025 who had cardiac arrest and received CPR in our hospital. Appropriate statistical analysis was conducted with SPSS software version 27 and p-value set significant if less than 0.05. Results: The mean age of patients was 58 ±10 years, male accounted 67.74%. Cardiac arrest is most common in elderly population and outcome is poor. Most common initial cardiac arrest rhythm was asystole (88.29%). We observed that there was no significant association between initial cardiac arrest rhythm and survival outcome (p=0.243). We also observed significant association between shorter duration of CPR in survival group (ROSC) of 21 to 40 years age group. Conclusion: In this study, we observed that there is an association between duration of CPR and return of spontaneous circulation. These findings highlight the importance of prompt and effective resuscitation efforts to optimize survival rates during cardiac arrest management.
