The Effect of Real-Time Audiovisual Feedback on Seafarers' Cardiopulmonary Resuscitation Training

This study is a quasi-experimental study with a nonequivalent control group pretest-posttest design conducted to compare and verify the effectiveness of Cardiopulmonary Resuscitation (CPR) training using a real-time audiovisual feedback device for seafarers. A total of 170 seafarers were randomly assigned to either the real-time audiovisual feedback (AVF) group or the non-feedback (NF) group in this study. Self-confidence, educational satisfaction, and performance ability were assessed through a questionnaire and equipment measurements. The collected data were analyzed using IBM SPSS Statistics 23, utilizing descriptive statistics, t-tests, chi-square tests, and Pearson correlation analysis. The results indicated that, following the training, AVF group had significantly higher educational satisfaction compared to NF group (p=0.001). However, no significant difference was found in self-confidence. After the training, AVF group demonstrated significant improvements in the rate (p<0.001), depth (p<0.001), recoil (p<0.001), and accuracy (p<0.001) of chest compressions compared to NF group. There was no significant difference in rescue breathing accuracy between the two groups after training. The correlation analysis results indicated a significant relationship among self-confidence, educational satisfaction, and chest compression accuracy within AVF group. Therefore, the use of real-time audiovisual feedback devices is essential in CPR training for seafarers.
