At 9:00 on June 14, 2024, the dispatch and command center of the Beijing Emergency Center received a call claiming that a man suddenly lost consciousness at home and was in critical condition.

While the dispatch doctor sent an ambulance immediately, the family members shouted over the phone: "What should we do! Help me! He is only in his 30s!" The dispatcher learned through questioning that the patient was in an unconscious and non-breathing state and immediate cardiopulmonary resuscitation is necessary. He held on to the call and connected to the Advanced Dispatch Online Life Support System (ADLS) and provided medical guidance to the caller through the phone.

"Is there anyone else around you? Is there an AED in the community? If there is, you can get it." The dispatch doctor calmly instructed: "Please kneel beside the patient, place the base of one hand on the lower middle section of the patient's sternum, which is the midpoint of the line connecting the two nipples, place the other hand on the back of this hand, and press down vertically with force. The pressing depth should be at least 5 cm. Please follow my pace to press, 1234, 1234..." The dispatcher concentrated his energy, listened carefully to every sound coming from the phone, and captured all feedback. While instructing, he encouraged the caller: "After pressing 30 times, perform 2 artificial respirations. Don't give up. Hang in there. The ambulance will be here soon."

On the other side of the phone, the caller followed the instructions and tried his best to rescue. The dispatch doctor paid full attention to the ambulance's driving trajectory on the screen and told the caller that the ambulance would be here soon. Five minutes later, the ambulance crew arrived at the scene, and the medical staff immediately took over the rescue. The dispatch doctor immediately established a green channel with the hospital emergency department to rescue the patient in time. Finally, with the efficient cooperation of all parties, the ambulance sent the patient to the hospital for further rescue rapidly.

According to the follow-up interview, the patient has recovered his breathing and heartbeat, and the resuscitation was successful. He is receiving further treatment.

Beijing 120 reminds you that the first witness should call 120 in time and perform effective cardiopulmonary resuscitation when facing an unconscious and non-breathing patient at the scene. When communicating with the dispatch doctor, it is necessary to calmly describe the situation at the scene, cooperate with the inquiries and follow the telephone medical guidance. Let us work together to save the lives.
