ABC means airway, breathing, and circulation. In first aid, it is a simple shorthand for checking the most important life-support priorities first.
What does ABC mean?
A stands for airway.
B stands for breathing.
C stands for circulation.
The idea is straightforward: if the airway is blocked, breathing is abnormal, or circulation has failed, the person may die quickly without urgent help.
Why does the ABC approach matter?
ABC helps first aiders focus on the biggest immediate dangers first instead of getting distracted by smaller problems.
It points you toward questions such as:
- Is the airway open?
- Is the person breathing normally?
- Does the situation suggest CPR may be needed?
Is ABC the same as a primary survey?
Not exactly.
ABC is the shorter shorthand.
Primary Survey is the broader rapid first check for life-threatening problems.
On this site, the more practical Australian first aid sequence page is DRSABCD, which expands the process to include danger, response, sending for help, CPR, and defibrillation.
How does ABC connect to the rest of the site?

Those pages now do the main practical work, while ABC remains the simple memory aid page.
Quick answer
ABC means airway, breathing, and circulation. It is a simple first aid shorthand for checking life-support priorities first, while Primary Survey and DRSABCD are the clearer practical step-by-step pages on this site.
