Purpose: This study compares the chest compression quality, and the willingness and confidence to perform cardiopulmonary resuscitation (CPR) before and after education between the compression only CPR (COCPR) group and the standard CPR (STCPR) group using manikins. Method: This study employs a randomized controlled trial design. A total of 219 and 214 individuals were randomly assigned to the COCPR and STCPR groups, respectively. Both groups were asked to perform CPR for 2 min before and after education. The willingness and confidence to perform CPR were surveyed through a questionnaire. Results: Before education, the STCPR group had a significantly higher mean chest compression depth and accuracy than the COCPR group for the entire 2 min. After education, the STCPR group had a significantly higher mean chest compression depth for 2 min and higher compression accuracy for late 1 min than the COCPR group. However, no significant difference in the willingness and confidence to perform CPR according to the compression method was evident. Conclusion: Repeated training is required to maintain chest compression quality. CPR education improves willingness and confidence to perform CPR.
