In the early morning of November 21, 2023, the Beijing 120 Dispatch and Command Center received a call. An anxious caller said that “My father has been feeling unwell in the heart all day. Now he is unconscious, and seems stop breathing!” “Please don’t hang up. I will send an ambulance immediately, and I will tell you what to do next after dispatching it." It took only 30 seconds for the dispatching doctor Chen Minrui to collect the key information and send the nearest ambulance to the scene. She calmed down and immediately carried out remote medical guidance for the caller. "The ambulance has been dispatched. I will guide you to carry out on-site first aid. If there is an AED in your community, send someone to get it immediately. Now I will teach you how to do cardiopulmonary resuscitation." Correct posture, chest compression location, compression frequency, and compression depth are all technical points for high-quality CPR and play a vital role in the rescue effect. Dr. Chen connected the phone to the Advanced Dispatch Life Support System Online (ADLS) to provide the caller with standard and effective emergency guidance.

Although the caller had never learned first aid knowledge, he focused on the step-by-step instructions given by Dr. Chen and performed the rescue operations calmly. "1.2.3.4, 1.2.3.4..." with the continuous encouragement and companionship of the dispatching doctor, the caller performed CPR continuously. Soon, the ambulance arrived at the scene, and the medical staff immediately started rescue operations. Thanks to the efforts of the emergency crew, the patient finally showed vital signs, and his breathing and heart rate gradually recovered.

The dispatch command center established a green channel with a nearby hospital, and the ambulance safely delivered the patient to the hospital for further treatment. Through a follow-up call, we learned that the patient was diagnosed with acute inferior and posterior wall myocardial infarction. Emergency surgery was performed as soon as possible after arrival. After the surgery, the patient was conscious and recovered well. With the joint efforts of many parties, the patient regained his "heart". A family that was almost broken was rescued.

Beijing 120 reminds you that before myocardial infarction, some patients will have symptoms such as fatigue, chest discomfort, palpitations after activity, shortness of breath, irritability, angina pectoris, etc. Angina pectoris attacks are more frequent, severe, and last longer than before. Some patients will have unexplained symptoms. It is necessary to pay attention to atypical symptoms, such as head and neck pain, toothache, back pain, severe cough, gastrointestinal discomfort, etc. and seek medical treatment in time. If first aid is needed, it is recommended to dial 120 in time, follow the professional medical guidance of dispatchers and cooperate with on-site first aid. It is necessary to learn more about first aid knowledge and skills, and work with professional first aid personnel to win precious time for patients at critical moments.
