Will you use this "life-saving artifact"

  In recent years, incidents related to sudden cardiac death have occurred frequently, and it has become a public health issue widely concerned by society. The data shows that sudden cardiac death is the main cause of death of cardiovascular disease in China. About 544,000 people die each year, and the success rate of out-of-hospital recovery is below 1%.

  At the two sessions this year, how to prevent sudden cardiac death and the configuration and use of automatic external defibrillators (hereinafter referred to as AEDs), known as "life-saving devices" in public places, have also become one of the hot spots of concern for delegates and members. In this connection, the reporter recently interviewed Professor Wu Lin, chief physician of the Department of Cardiology, Peking University First Hospital, who has long been engaged in the research and prevention of sudden cardiac death.

Non-professional medical personnel can also use AED to rescue patients with sudden cardiac death

  The human heart is like a power pump, delivering oxygen- and nutrient-rich blood to every cell in the body. When a fatal heart rhythm disorder such as cardiac arrest occurs, the heart cannot effectively pump blood, and the patient will face the threat of death.

  "When the heart cannot effectively contract and lose power, it will be dark for 3 to 5 seconds, and it will lose consciousness because of insufficient blood supply to the brain in 8 seconds, and seizure-like seizures may occur in 15 seconds." Wu Lin According to the introduction, if someone can call the emergency system immediately and press the patient's heart at the same time within 4 minutes, it is best to use AED, a simple defibrillator, for cardiopulmonary resuscitation, so that the patient's survival rate can be as high as 50%. "Every 1 minute delay in treatment time reduces the probability of survival by 10%."

  He pointed out that if the intervention is not carried out in time, the brain tissue will be irreversibly damaged due to hypoxia for more than 4 to 8 minutes, and then die quickly. Even if the heart recovers from beating, it may cause damage to multiple organs, especially brain damage.

  "Once a patient with sudden cardiac death appears around him, it usually shows a sudden loss of consciousness and the call does not respond." In this regard, Wu Lin proposed measures that can save the patient's life-dial 120 on the spot and call his heart at the same time. Fortunately, early AED defibrillation, "this can increase the success rate of first aid by 3 times."

  What is AED? Wu Lin said that AED is a portable medical emergency equipment. Once it is turned on, it can automatically guide the operation process, automatically detect heartbeat, and automatically defibrillate when needed. It is very simple and convenient to use. AEDs are deployed abroad in places with high incidence of sudden cardiac death and even on international flights.

  "Non-professional medical personnel can also use AED to rescue patients with sudden cardiac death, and the AED in some public places is marked as" requires professional use "is inappropriate, affecting the rescue of patients, hoping to be corrected from the legal level "Wu Lin emphasized that if you want to know the storage location of the AED in your area, you can use the mobile phone WeChat" search one search "function to search for" AED navigation ".

Urgent need to popularize AED configuration and protect the rights and interests of rescuers

  Public places such as airports, train stations, subway stations, large shopping malls, and sports venues are often high-risk areas of sudden cardiac death. Configuring AED can effectively improve the success rate of sudden cardiac death rescue.

  At present, the situation that China has too few AED configurations and fewer applications is common. Wu Lin admitted that although the allocation rate of AED in public places in Shanghai, Shenzhen, Dalian and other places has increased significantly, as far as the country is concerned, there are only about 20,000 AEDs in public places around the country, and less than 1 per 100,000 people. Taiwan is far from being able to meet the need for first aid for the sudden death of more than 41 people per 100,000 in China. He suggested that governments at all levels should pay attention to and support the deployment of AED.

  It is reported that the number of AEDs in European and American countries is more than 400 per 100,000, Japan is close to 300 per 100,000, and Hong Kong is 10 per 100,000.

  It is of course important to improve the configuration of AED in public places, but the protection of the rights of rescuers cannot be ignored. Wu Lin emphasized that the rights and interests of the rescuers should be protected from the legislation, exempt from any responsibility they have to bear to save people, and should be legally avoided to be blackmailed or cause trouble-otherwise, even if more AEDs are installed, no People dare to rescue the sudden death, but it does not help.

  "In order to improve the overall first-aid level, integrating the distress response system and strengthening the ability to locate the distress call are important measures for rapid treatment." Wu Lin added.

Improve public awareness and ability of first aid

  The success rate of on-site resuscitation of sudden cardiac death depends not only on the level of first aid of doctors and medical ambulance personnel, but also on the public. "In particular, the level of knowledge of witnesses at the scene of the accident, the level of knowledge of first aid, and the ability to participate in rescues and perform preliminary cardiopulmonary resuscitation in a timely manner." Wu Lin emphasized.

  After the sudden cardiac death of the patient, it is critical for the witness to be able to perform chest compressions or defibrillation on the patient in time after calling for help. "Purely waiting for the arrival of first-aid personnel can only reduce the success rate of recovery. This phenomenon is a manifestation of the poor public awareness of first-aid on the spot and the poor first-aid ability of our country." Wu Lin pointed out.

  At present, the way for most people to obtain first aid knowledge is through the media or publicity platforms of some medical institutions, and there are very few opportunities to obtain first aid knowledge and skill drills through professional training institutions. He suggested that the knowledge of first aid for CPR should be popularized and promoted, so that first aid knowledge should become a compulsory course for the public, which can be incorporated into all levels of school education, as well as induction training courses for key occupations such as police, firefighters, guards, flight attendants, and salespersons. Form a complete education and training system to allow more people to learn first aid.

  Wu Lin finally emphasized that the best way to reduce sudden cardiac death is to prevent its occurrence, including primary prevention for individuals who may have sudden death and secondary prevention for survivors of sudden cardiac arrest. "For high-risk populations with a family history of sudden death or multiple risk factors for cardiovascular disease, we must actively carry out sudden death risk assessment and individualized prevention and treatment in order to effectively reduce the incidence of sudden cardiac death."
