Toddler practices CPR on a doll

A 2-year-old boy named Yiyi has become famous on the internet due to a video clip that records him performing cardiopulmonary resuscitation.

The video shows the little boy kneeling on the ground in front of a toy baby. When the photographer - his mother Wang Zhijuan - prompted him with the command, "wake up", he put his right middle finger and index finger to the doll's neck to check what in a human would be the pulse on the carotid artery.

When he heard the words "the patient has no spontaneous breathing, no aortic pulse, now start chest compression immediately", the boy's hands overlapped each other on the doll's chest, and he compressed downward as his mother counted compressions.

The boy also skillfully mimicked artificial respiration when his mother said, "open the airway, give artificial ventilation", and had a sense of relief when he heard her say, "the patient's spontaneous breathing restored; the aortic pulse restored".

Yiyi then patted the doll on the shoulders and told it to "wake up".

Wang Zhijuan is a nurse with Dalian Maternity Hospital. Since the hospital is going to hold a competition on first aid skills, Wang practices performing CPR on the doll at home every day.

"One day when I came back from work, I was surprised to find that Yiyi was performing CPR on the doll too," she recalled.
