Approach and steps for Basic Life Support (BLS)

Whenever we encounter a victim who is either responsive or unresponsive, we must be aware of what steps to Approach and steps for Basic Life Support (BLS) . The techniques involved in First Aid are relatively simple, but if they are used in an emergency, they can save lives.

Part 5: Adult Basic Life Support | Circulation

In the case of an unresponsive victim, we should first and foremost check for dangers surrounding the victim. The following steps must be followed if the area is clear:

A – Airways. By lifting their chins, they will be able to open their airways.

B – Breathing. Watch their chest for signs of breathing by putting your ear to their mouth.

C – CPR and circulation. CPR should be performed if they are not breathing (we will visit this in a later chapter)

D – Defibrillation. In the event that no result is obtained, use an automated external defibrillator (AED) to restart the heart (we will discuss this in more detail later).

Recovery Position

In cases of unconsciousness but still breathing, it is crucial the person is put in a position that will prevent them from choked on their own vomit and keep their airways clear.

  1. As soon as you have reached the victim, crouch down next to them.

  2. Bend their elbow and make sure their palm is facing up while placing the arm nearest you at right angles to their body.

  3. They should place the back of their hand against the side of their cheek with their other arm (furthest from you) across their chest.

  4. Pull their knee towards you, rolling their body onto its side, while grasping the leg furthest from you, bending it and pulling it towards you.

  5. Ensure that the airways are always open.
