The CPR promotional video featuring 'Cindy,' the pet dog of Shin Dong-gyun, a firefighter at the Gyeonggi Fire and Disaster Headquarters, has garnered significant attention by recording 1.8 million views. The video shows Cindy discovering a cardiac arrest patient and performing chest compressions, along with guidelines on how to respond in a cardiac arrest situation. Cindy, a Jack Russell Terrier, is a small dog with excellent training abilities, quickly learning simple actions and successfully performing CPR maneuvers almost every time. The video won the grand prize at the Ministry of Personnel Management's competition, and the entire prize money was donated to support residents affected by fires. Shin Dong-gyun plans to use Cindy to create various fire safety education content in the future.
