The concept of survival chain includes

The proposal of "survival chain" is a major breakthrough in the concepts of cardiopulmonary resuscitation (CPR) and emergency cardiac care (ECC), which emphasizes the extreme importance of time to the success of resuscitation. From 65438 to 0988, The Chain of Survival first appeared in the conference of Civil Cardiopulmonary Resuscitation in the form of a slogan, which quickly attracted the attention of experts and the public, and its content was constantly enriched and improved. JEMS magazine published an overview of "survival chain" in 1989, and further discussed it in the first issue of 1990 Journal of Emergency Heart Care. The American Heart Association (AHA) formally introduced the concept of "survival chain" in the Guide to Cardiopulmonary Resuscitation and Cardiovascular First Aid formulated in 1992, and it was recognized by the International Liaison Committee for Resuscitation (ILCOR) in 1997. The "survival chain" includes four links, emphasizing four.

"Good morning"

Call the police for help as early as possible: call 120 or the local emergency number;

Early resuscitation: Basic cardiopulmonary resuscitation, including chest compressions and artificial respiration, should be given immediately by witnesses (mainly the public without medical professional training).

Early defibrillation: The patient is most likely to survive if the first electric defibrillation is completed within 3-5 minutes after the occurrence of SCA.

Early advanced life support: early advanced life support after resuscitation of medical staff. Clinical and epidemiological studies have confirmed that an efficient cardiovascular system should be established, whether before operation or in hospital.
