A Comparative Study of Hands - Only CPR between Counting out loud Method and Soundless Method

Objective: This paper compares the accuracy of Hands-only CPR by counting methods and is targeting middle aged women, the age group which has the highest chance of witnessing cardiac arrest. With these comparison results, this study aims to provide the basic data to prepare the First Responder courses covering CPR.
Methods: The subjects for this study are the sophomore Social Welfare Administration students at D University which is located in G city. First, the entire 145 students received three hours of the basic life support training, and then 90 study participants who met the study conditions were selected. Then, the probability assignment was used to assign 45 students into two experimental groups -Group A used the Count out loud method and group B used the Soundless method. Each group performed 2-minute dummy experiment and there were no dropouts.
Results: In the 2-minute experiment, the total hands-off time and the average hands-off time was significantly different between two groups consecutively (p=0.015), (p=0.020). There was a similar rate of change of chest compression depth rate during the periods of 61∼75seconds(p=0.018), 76∼90seconds(p=0.005), 91∼105 seconds (p=0.005), and 106∼120seconds(p=0.010). There was also a big differences between two groups in the subjective fatigue(p<0.001). There was no significant difference between two groups about the accuracy of the chest compressions and average chest compression depth, but in the chest compression depth variability, which was tested every 12 seconds to find the timely variation of compression depth, three was a significant difference(p=0.011).
Conclusion: In this study, which involved middle-aged women conducting Hands only CPR dummy experiment for 2 minutes, the Soundless method(counting numbers in mind without sound) reduced the Hands-off time which made no significant difference for the accuracy of chest compressions compared to the Counting out loud method. The Soundless method also showed significantly lower rate of subjective fatigue which participants feel during CPR and the frequency of chest compression depth as time went by. If additional researches are done, and more effective chest compression methods are figured out, even the public will be able to provide better quality CPR.
