Therefore, immediate treatment is needed by people around the victim (bystanders). Early cardiopulmonary resuscitation (CPR) provided by bystanders reduces death rate associated with OHCA. However many bystanders can not do CPR and the majority were young people. Objectives: This research aimed to investigate the effect of cardiopulmonary resuscitation (CPR) simulations on (knowledge, attitudes, and skills) of Youth Organization’s members in Candibinangun Village, Pakem District, Sleman.
