What does the 'A' in ABC stand for in first aid?

In the context of first aid, the 'A' in ABC stands for Airway. The ABC approach is a systematic method used to assess and address the most critical aspects of a patient's condition. By ensuring that the airway is clear and unobstructed, a first aider can significantly increase the likelihood of oxygen reaching the lungs and the patient being able to breathe effectively. This is a priority in emergency situations, as a blocked airway can lead to a deterioration in the patient's condition and potentially result in life-threatening scenarios. The focus on airway management underscores its importance in the overall assessment and treatment process in first aid.
