The ABC of first aid stands for Airway, Breathing, and Circulation. It represents the critical steps to assess and address life-threatening conditions in a person who is injured or ill.
Here's a breakdown of each component:
-
A - Airway: Ensuring the patient has a clear and open airway is the first priority. This means checking for any obstructions like the tongue, foreign objects, or swelling. Techniques like the head-tilt-chin-lift or jaw-thrust maneuver may be used to open the airway.
-
B - Breathing: Once the airway is open, assess if the patient is breathing adequately. Look for chest movement, listen for breath sounds, and feel for air movement near the mouth and nose. If the patient is not breathing or is breathing inadequately, rescue breaths or ventilation with a bag-valve-mask (BVM) may be necessary.
-
C - Circulation: After addressing airway and breathing, assess the patient's circulation. Check for a pulse (carotid or femoral are common sites in emergency situations). If there's no pulse, chest compressions (CPR) are needed to circulate blood. Control any external bleeding by applying direct pressure to the wound.
The ABCs are a fundamental principle in first aid and emergency medical care, providing a systematic approach to prioritize interventions and maximize the chances of survival. Remember to call for emergency medical services (EMS) as quickly as possible, so that professionals can provide advanced care.
