Sudden cardiac arrest (SCA) is the most common cause of death in the world. This manuscript highlights the various challenges in prevention and early management of SCA and also discusses the current state of SCA awareness. The manuscript also outlines the various national and international initiatives in improving SCA awareness and their impact on improving outcomes in SCA. Various campaigns have strived for widespread dissemination of cardiopulmonary resuscitation training and advocated for broader public access defibrillator availability. Finally, the manuscript describes future directions including harnessing technology with voice command and artificial intelligence to allow lay person deliver effective CPR, to improve EMS response times, and to allow wider CPR knowledge dissemination in schools and places of employment. Future research should be focused on optimizing SCA outcomes among vulnerable populations and minorities. Advancements in resuscitation science and use of big data for improvement of EMS services will improve outcomes in SCA.
