Community-Wide Dissemination of Bystander Cardiopulmonary Resuscitation and Automated External Defibrillator Use Using a 45-Minute Chest Compression-Only Cardiopulmonary Resuscitation Training.

Background Little is known about whether cardiopulmonary resuscitation ( CPR ) training can increase bystander CPR in the community or the appropriate target number of CPR trainings. Herein, we aimed to demonstrate community-wide aggressive dissemination of CPR training and evaluate temporal trends in bystander CPR . Methods and Results We provided CPR training (45-minute chest compression-only CPR plus automated external defibrillator use training or the conventional CPR training), targeting 16% of residents.
