Abstract: Cardiopulmonary resuscitation (CPR) guidelines recommend target values for compressions, ventilations, and CPR-free intervals allowed for rhythm analysis and defibrillation. Compression fraction is defined as the proportion of CPR time spent providing chest compressions. Studies evaluated the incremental benefit of higher chest compression fraction on survival to hospital discharge. From the literature available so far, it is almost found that there is a positive association between increased chest compression fraction and ROSC. And there are studies that show negative correlation of chest compression with ROSC. So the present study conducted by us(where the study population is the patients in Emergency Department and the in patients in KimsHealth hospital who were in cardiac arrest) would be helpful to validate the association of CCF in attaining ROSC. In our study, we were trying to find a correlation between chest compression fraction and survival of the patients. Aim: To find the independent association between chest compression fraction during cardiac arrest and the outcome in patients in KIMS HEALTH by evaluating return of spontaneous circulation and percentage of survival of the patients at the time of their hospital discharge by observation and analysis. Primary Objective: To determine the independent association of chest compression fraction and outcome in patients by evaluating the return of spontaneous circulation in them as well as percentage of survival of the patients at the time of their hospital discharge by observation and analysis. Design, Setting and Participants: The study was done on the patients in emergency department and In-patients in KimsHealth who were in cardiac arrest in the year 2020-2022. Study Population: Patients who were in the emergency department and In ? patients (who were admitted in the hospital) with cardiac arrest in the age group above 18 yrs in KimsHealth. We excluded all out of hospital cardiac arrest patients, patients with Unwitnessed cardiac arrest and we also excluded patients whose bystanders refused for the participation in the study. Method of Study: For our study, a stopwatch was switched on when the code blue was announced and chest compression is initiated. For each time of interruption of CPR, the stopwatch was paused and was resumed when CPR is started again. As a part of the study, the total time for CPR and time taken for chest compression was noted. Results: In our study, out 0f 96 patients, 56 % (majority) patients were in chest compression category81 - 100 % .50 % of the patient?s attained ROSC. Out of the people who attained ROSC, 74 % people were in chest compression fraction category 81% -100 % and only 33.33% of patients were in the category 41-60 %. People who attained ROSC were followed up till they got discharged from the hospital. Among the patients who improved at the time of their discharge, majority (57 %) received CPR with chest compression fraction 81-100 % and 33.3 % people had received chest compression with CCF of 41-60 percentage and the rest received CPR with CCF of around 23.6 %. Conclusion: Thus, this study was really helpful to find the validate the association between chest compression fraction with ROSC and survival to hospital discharge. We conclude that even though the quality of CPR depends on various factors, monitoring and improving chest compression fraction of patients in cardiac arrest in a hospital would bring better clinical outcome in them.
