D – DANGER
Ensure that it is safe to approach and address any hazards that may be a risk such as from other players or environmental hazards, e.g. lightning, etc.
R - RESPONSE
Check the level of responsiveness of the player by SPEAKING to him/her. If they don't reply, try to rouse the player by lightly TOUCHING (squeezing) their arm. If they speaks back to you, you know the airway is open, the lungs are getting oxygen from the air and the heart is pumping enough blood around the body. If an injured player is unresponsive, shout for help as loud as you can. If nobody comes to assist and you have a mobile phone, call someone to help.
A - AIRWAY
B - BREATHING
C - CIRCULATION
Life depends upon oxygen being pumped around the body. Therefore, in order to stay alive, we need to be able to get oxygen into the body through an OPEN AIRWAY. The oxygen needs to get deep into the lungs and bloodstream through effective BREATHING and then pumped around the body by the CIRCULATION. If you don’t have A, you can’t have B and will never achieve C. Achieving an open airway is the absolute priority in all casualties. Without it, the injured player will probably die.
