At 2:50 pm, the boy's heart completely stopped beating while the ECMO machine was still on the way. From this moment on, continuous chest compression was needed to keep him alive.

For such an emergency, the hospital organized 30-odd professionals to perform the task. To guarantee the efficacy of the action, relays were set up, with each person performing the chest compressions for one to two minutes and then resting while another did a set of compressions. Otherwise, a person would tire and the compressions would not be powerful enough.

In this way, the 30-odd professionals tried hard to save the boy until the machine arrived and started working.

By the time the machine was operable at 7:30 pm, health workers had performed over 30,000 chest compressions.

"We are desperate to save every young life that is at risk with all our efforts. The world is not that terrible because we love you in silence," one staff member who participated in the relay posted on WeChat, a popular social networking platform in China.

The boy's heart started beating again in a very weak way and he is still under treatment at the time of this writing.
