Cardiopulmonary resuscitation (CPR) is a life-saving procedure that should be able to perform by everyone. It is the only critical rescue procedure that can be done during a sudden cardiac arrest event. There are various technology-based training methods designed to ensure the procedures are well grasped by the public, such as virtual reality (VR), augmented reality (AR), and smartphone-based training. Those efficacies of technology-based CPR training and content remain divisive, leading to CPR success far below expectations. This initial study is to explore effective operative ways of CPR training using a technology approach through a systematic review. The entire search of information was guided by keywords related to technology-based CPR training, ‘cardiopulmonary resuscitation’ OR ‘training’ OR ‘community CPR training’ OR ‘CPR’ OR ‘cardiac resuscitation’ OR ‘technology-based’ OR ‘virtual reality’ OR ‘smartphone.’ The protocol used based Systematic Reviews Protocols (PRISMA). Data synthesis was analyzed using the Microsoft Excel format. The thematic analysis showed three important points, 1) Smartphone-based as a CPR training instrument, 2) Effective content for CPR training 3). Technology-based CPR training uses a smartphone as a key instrument. Three important things to consider before conducting training in this era of high technology are the ‘Training Instrument’, Training Intervention, and Intervention Outcome. The training instrument should explain the instrument to be used as key technology-based CPR training. The training Intervention will focus on the dynamic contents of intervention processes, and the ‘Intervention Outcome’ will measure the success of the entire training based on the system invented. We cannot run away from the participation of advanced technology in our lives, including daily tasks and training that have been proven effective. The possibility of CPR training conducted through face-to-face may be one of the causes of the failure of the given training due to time, frequency, distance, staff selection, and unchanged program. This study will be conducted in the future and will give a positive sign.
