1. Why is early action important in the chain of survival?
Early action improves the chance of survival because help starts quickly. It gives the casualty the best chance, but it does not guarantee recovery.
Before giving care, a pool lifeguard checks the scene and the casualty. This part of the theory exam is built around the DRSABCD action plan (Danger, Response, Send for help, Airway, Breathing, CPR, Defibrillation) used across Australia and New Zealand under ANZCOR guidance.
Topics include scene safety, protecting yourself with standard precautions, checking response and breathing, the recovery position, the chain of survival, and recognising shock.

Early action improves the chance of survival because help starts quickly. It gives the casualty the best chance, but it does not guarantee recovery.
If a casualty is unresponsive but breathing normally, the recovery or lateral position helps keep the airway open. CPR is for a casualty who is not breathing normally.
The chain of survival is a series of actions that improve the chance of survival after a cardiac arrest. It starts with early recognition and calling for help, followed by CPR, defibrillation, and advanced care.
The recovery position is for an unresponsive casualty who is still breathing normally. If breathing is not normal, CPR is needed instead.
Send for help means calling 111 or getting another person to do it. Do this early when the casualty is unresponsive.
Talk to the person and gently touch them to check whether they respond. If they do not respond, move on to the next step in the assessment.
The airway step is about making sure air can move in and out of the casualty's mouth and nose. It comes before checking breathing.
CPR is started when the casualty is unresponsive and not breathing normally. This means the heart and lungs need immediate help.
