Basic Life Support in Adults

The Chain of Survival:

To maintain the supply of oxygen to the brain we require:

  • An open airway to allow oxygen to enter the body
  • Adequate breath to transport oxygen to the lungs
  • An effective pumping action of the heart to deliver oxygen to the vital organs

As first aiders, we can supply the first 3 steps in this chain
