What is a Chain of Survival in first aid?

La Chain of Survival It refers to a series of steps to follow for a victim who is experiencing a health emergency situation, such as a heart attack or cardiorespiratory arrest. The application of this series of actions is also known Basic Vital Support.

The correct performance of these steps will ensure that the victim's chances of survival remain greater than the dangers and consequences that could cause a decrease.


The importance of the Chain of Survival 

In our daily lives, whether in the work or family environment, we can witness emergency situations in which we must act immediately in order to guarantee the survival of the affected person.

We tend to think that only those people who suffer from cardiovascular diseases can be affected and, not only that, these episodes can appear in an obvious way without a prognostic cap prior to the onset and which are considered non-traumatic pathologies.

For that, It is vital to be able to reconèixer at certain times for respiratoryknow how to activate health care by warning the emergency services and, for the purposes of this, know how to perform CPR maneuvers correctly in order to help the victim. All in all, it can be converted into parts of the chain of survival and, if one of these actions is unsuccessful or not executed correctly, the victim's chance of survival decreases considerably.


Com dur a terme the Chain of Survival

The way to proceed at the time of dur a terme aquesta Chain of Life, a proper order must be respected in order to provide a correct application of the techniques and safe emergency aid to the affected person.

The first step in the chain of survival is calling 112



Recognition and harmful demand

We suspect that a victim suffered a heart attack or cardiac infarction when he had severe pain in the center of the pit, radiating to his arms or other legs of his chest, and that he suffered abundantly. if we find a victim who is not breathing; We will immediately activate the emergency services by calling 112. We will suspect cardiorespiratory arrest in all patients who have a seizure.

Cardiopulmonary resuscitation (CPR)

To maintain the chain of survival after a cardiorespiratory arrest, immediately begin Basic Vital Support (BLS) maneuvers, performing CPR with quality chest compressions and rescue insufflations.

Automated external defibrillation

For most cardiorespiratory arrests, the most effective treatment for the patient is the performance of an electrical shock (defibrillation) with an AED. Now it will be possible for the body to return to normal operation.

For every minute that the electrical discharge occurs, the chances of survival decrease by approximately 10%. Performing a defibrillation for 3-5 minutes after waking can achieve a survival rate of 50-70%.

Post-resuscitation cures

After performing a successful BLS, the presence of medical personnel is necessary to provide advanced cures to restore the patient's quality of life. More information about training in basic vital support and cardioprotection afterwards.
