¿Qué es la Cadena de Supervivencia?

When someone suffers a cardiac arrest outside the hospital, there is a chain of events that can help increase the chances of survival. This is known as the Survival Chain Concept. A term coined by the American heart Association   in 1991, which in its document ‘ Improving Survival from Sudden Cardiac Arrest: The Chain of Survival Concept ‘ states that all communities should know and adopt the principle of early CPR and defibrillation.

So what is the Survival Chain? Composed of four links, the first three in the chain can be executed by ordinary people who have basic knowledge about life-saving techniques. The final step can only be carried out by paramedics. If all stages are performed in rapid succession, they can increase the chances of survival of a person suffering from a cardiac arrest.

1. Acceso temprano

The first step in the chain is an early access. This refers to a person able to recognize the signs of a cardiac arrest and get help. Normally there are no symptoms that reveal its occurrence; However, if someone experiences a stop:

  • Lose consciousness
  • Not responding
  • Do not breathe or breathe abnormally

If you encounter a person who thinks you may be suffering from a cardiac arrest, call Emergency immediately and start CPR.

2. RCP Temprana

The second step of the Survival Chain is an early CPR: this includes practicing chest compression to keep the victim’s heart functioning until a defibrillator is available. Many organizations offer CPR training courses for the general public.

3. Desfibrilación temprana

The third step is early defibrillation. Having an AED on hand in an emergency of sudden cardiac arrest can mean the difference between life and death. A defibrillator is used to send an electric shock to the heart and return it to its normal rhythm. For every minute that passes without defibrillation, the person’s chances of survival decrease by 10%.

Installing a defibrillator in your workplace or community space is the best way to ensure that one is available by hand.

The fourth step in the chain is an advanced early care with medications and maneuvers of the medical or nursing staff, whose advanced emergency procedures can be effective only if immediate and if preceded by the actions of the second and third steps of the chain, correctly performed Waiting for the arrival of the ambulance.
