Evaluation of Efficacy of Online Real-time Home CPR Training Program

The purpose of this study is to evaluate the effectiveness of a real-time home CPR(cardiopulmonary resuscitation) training program. The study participants will be allocated to two different CPR training programs. The intervention group will participate in the real-time home CPR training program while the control group will participate in the conventional CPR training program. The investigators will compare the quality of chest compression between the two study groups. The investigators hypothesize that the new real-time home CPR training program is non-inferior to the preexisting conventional CPR training program.
