Background:The study aimed to determine the average chest compression fraction (CCF) and its correlation with influencing factors to optimize blood flow during resuscitation, aiming for a minimum of 60%.Materials and Methods:Prospective observational study on 50 cardiac arrest patients, analyzing chest compression fraction (CCF) and identifying associations using Spearman's correlation coefficient and individual student t-tests.Results:The study revealed a satisfactory average Chest Compression Fraction (CCF) of 71.66 +/- 7.79, with diabetes mellitus being the most prevalent medical condition, and no significant correlation between compression depth, rate, and recoil.Conclusion:The average cardiac arrest (CCF) in ED patients decreased with longer code durations, daytime events, defibrillator use, increased team members, male providers, and chest compressions.
