The ABCs of first aid are a life-saving method used to assess and treat emergencies in the correct order. They help responders focus on the most critical problems first to keep a person alive until medical help arrives.
The ABCs of First Aid Are:
- A – Airway
- B – Breathing
- C – Circulation
This system is used worldwide by first aiders, paramedics, and healthcare professionals.
What Does A Mean in the ABCs of First Aid?
A – Airway
The airway must be open and clear for oxygen to reach the lungs.
How to check the airway:
- Is the person conscious?
- Can they talk or make noise?
- Is the mouth or throat blocked?
What to do:
- Tilt the head back and lift the chin
- Remove visible obstructions if safe
- Do not insert fingers blindly into the mouth
➡️ A blocked airway can cause death within minutes, making this the first and most important step.
What Does B Mean in the ABCs of First Aid?
B – Breathing
After opening the airway, check if the person is breathing normally.
How to check breathing:
- Look for chest rise
- Listen for breath sounds
- Feel for air on your cheek
(Do this for no more than 10 seconds.)
What to do:
- If breathing normally, place the person in the recovery position
- If not breathing, begin CPR or rescue breaths (if trained)
- Call emergency services immediately
➡️ Breathing supplies oxygen to the brain and vital organs.
What Does C Mean in the ABCs of First Aid?
C – Circulation
Circulation ensures blood is flowing and severe bleeding is controlled.
How to check circulation:
- Look for heavy bleeding
- Check skin color and temperature
- Watch for signs of shock
What to do:
- Apply firm pressure to stop bleeding
- Elevate the wound if possible
- Keep the person warm
- Begin chest compressions if there is no pulse (if trained)
➡️ Severe blood loss can be fatal even if the person is breathing.
