The busy summer season can take you almost anywhere — baseball fields, backyard cookouts, long workdays, or road trips across the country. Regardless of where you are, summer is a reminder that emergencies like cardiac arrest can happen anywhere. More than 350,000 out-of-hospital cardiac arrests occur in the United States each year, and 90% of people will not survive, according to the American Heart Association. Sudden cardiac arrest can happen anytime, anywhere. People often hesitate to step in.
