Bystander CPR research focuses on studying strategies to increase the number of people who are willing and able to provide cardiopulmonary resuscitation (CPR) to individuals experiencing sudden cardiac arrest in a public setting. This research area examines factors that influence bystander response to cardiac emergencies, such as knowledge, training, fear of legal implications, and social norms. The goal of bystander CPR research is to improve survival rates following cardiac arrest by empowering more individuals to take action in these critical situations.
