The Effect of Verbal Encouragement in CPR Performance on the Accuracy of CPR Techniques


  • Department of Clinical Exercise Physiology, Seowon University, 377-3 Musimseoro, Heungduk-gu, Cheongju, Chungbuk, 28674, South Korea


Objectives: To investigate the helpful techniques for Cardio Pulmonary Resuscitation by performing a comparative analysis of CPR between an encouragement and a non-encouragement group based on the AHA education program. Methods/ Statistical Analysis: This research was carried out by selecting 42 university students as a test group who had acquired a 2011 Health Care-Provider certificate issued by the AHA while attending Chungbuk University in C city. Informed consent was received from all participants in accordance with legal procedures. An average and standard deviation for each variable was calculated using the SPSS 12.0 version statistical program, and the gap between the averages values of each technique was verified using a Paired Samples Test. Findings: The encouragement language used in this study seems to have a tone of assertive sentences because it was directly quoted from the sentences in AHA education video, and it may have restricted a participant from performing techniques with more tension. Therefore, if the encouragement instructions are written using imperative sentences or suggesting sentences, it can be expected to increase concentration on the accuracy of CPR. Applications: This study provides proof that the verbal encouragement improves the accuracy and the speed of CPR; it is hence suggested to apply in the classroom for more efficient education.
