HeartSaver is a South Korean manufacturer focused on accessible CPR education and emergency-readiness products. Its flagship product, HeartPush, is a compact, portable training device that helps users practice chest compressions wherever they are. Weighing 86 grams, it provides an audible click when compressions reach the indicated depth of 5 cm and rhythm of 100–120 compressions per minute. A built-in whistle rated above 100 dB can also be used to signal for help in an emergency.

Alongside its training device, HeartSaver offers hands-on CPR education for schools, businesses, public organizations, and community groups. Programs include on-site workshops, hybrid sessions, instructor-led courses, group classes, train-the-trainer options, and certification packages. Sessions can be tailored for audiences such as students, educators, employees, and caregivers, with guided practice, demonstrations, and take-home materials.

HeartSaver serves retailers and distributors through bulk pricing, product and training support, marketing assets, custom packaging options, and fulfillment services. Its products are positioned for medical supply, education, outdoor safety, lifestyle, and online retail channels, helping partners bring practical CPR training tools to a broad audience.
