Basic Life Support (SVB)


El Basic vital support It is a set of maneuvers that make it possible to identify if a person is suffering a cardiorespiratory arrest and to apply a temporary substitution of respiratory functions through said maneuvers until the victim can receive medical attention.

It is recommended to start BLS as soon as possible, since every minute that passes the victim has a greater chance of suffering neurological sequelae, increasing the risk of death. The main objective of a Basic Life Support is to re-establish the basic vital functions, achieving oxygenation of the tissues.

The importance of Basic Life Support

Most of the population admits that they do not have sufficient knowledge to be able to apply a BLS correctly. It is a very common mistake in most societies, since knowledge of these maneuvers allows more peace of mind for the person who is suffering a cardiorespiratory arrest.

Controlling your nerves in a situation like this is the key to carrying out the SVB correctly since it lacks complexity when executing it. As a counterpart, we are talking about a decisive action that declines between the visa and the death of a person.

How to apply a Basic Life Support maneuver? 

1. Ensure safety

We will approach the victim making sure there are no dangers, such as vehicle traffic, debris, electrical cables, falling objects, etc. We will secure the area, even if we are on a highway or if we are on a public highway, we will try to give space to the perimeter where the victim is.

2. We will activate the emergency system

We will clearly explain the place where we are and the situation in which we have been involved. If we are accompanied, we will ask you to call 112 and we will send you to look for an AED. If we are alone, we will call 112 (if necessary, leaving the victim alone). We will activate the hands-free of the mobile to facilitate communication with the 112 operator.

This is one of the first steps to follow, since while professional medical services come, we can apply Basic Life Support mechanisms to keep her alive.

3. Check if the victim responds

If we consider that it is CONSCIOUS and breathing, we will follow the following steps:

  • We will leave the victim in the position we found him.
  • We will assess any injuries or medical problems you may have.
  • If necessary, we will activate the medical emergency system by calling 112.
  • We will reassess the victim regularly.

If we consider that it is UNCONSCIOUS, we will follow the following steps:

  • We will place the victim face up.
  • We will open the airway by performing the forehead-chin maneuver, with one hand on the forehead and the index and middle fingers of the other hand on the chin.

4. We will check if you are breathing normally

Maintaining the forehead-chin maneuver and looking towards the victim's feet, we will bring our cheek to his mouth, observing if the victim breathes normally for a maximum of 10 seconds.

  • If you breathe normally We will place the victim in a lateral safety position (PLS) and then we will activate the medical emergency system by calling 112. Until the ambulance arrives, we will continue to check that the victim is breathing.
  • If you are not breathing normally or are not breathing we will consider that he has abnormal or agonal breathing when the victim makes puffs without displacement of the chest. It will be understood that the victim is not breathing. We will place the victim on a firm surface (example: the floor) and face up.

5. We will start chest compressions

Every victim who suffers a cardiorespiratory arrest needs blood to flow through the vital organs, we will achieve this by performing compressions in the middle of the chest.

After 30 compressions we will perform 2 insufflations. Immediately after, we will perform 30 compressions again, following the 30:2 sequence. If there is more than one rescuer, they will be relieved every 2 minutes, avoiding the interruption of compressions between the reliefs.
