What is the chain of survival?

It means that it is composed of five interrelated links: early access (calling for help), early cardiopulmonary resuscitation, early defibrillation, early advanced life support and comprehensive treatment after cardiac arrest.

After early detection, immediately notify the nearest rescue agency and accurately report the patient's basic condition and location. Unobstructed early access is a prerequisite for patients to receive professional treatment. my country's medical professional emergency communication telephone number is "120", and some cities have now opened this channel.

The function is to define the first witness (first responder), emergency dispatch, emergency service personnel, emergency doctors and nurses as a team to work together in an orderly manner to save lives.

Extended information

While early cardiopulmonary resuscitation is clearing the early pathways, for those whose breathing and heartbeat have just stopped, basic cardiopulmonary resuscitation - artificial respiration and chest external surgery - should be implemented immediately on the scene. Heart Squeeze, or BLS, usually represented by English letters.

Early defibrillation: The normal beating of the heart is contraction and relaxation according to certain rules. When the heart experiences ventricular fibrillation, the myocardium is in a state of chaotic peristalsis, and the heart loses its function of expelling blood and maintaining circulation. , and soon came to a complete standstill and stopped. If ventricular fibrillation is removed in time and the heart can return to normal beating, lives can be saved.

Immediate defibrillation at the scene is the key to rescuing patients who die suddenly. A simple automatic defibrillator should be used immediately within 10 minutes after sudden death. And 10 minutes later, even with the most advanced defibrillator and the most skilled professional doctors, the rescue results were far from satisfactory.
