In case of road accidents, your first step for the injured person should be to

In emergency first aid for road accidents, the primary survey follows the 'ABC' protocol: Airway, Breathing, and Circulation. The first priority is ensuring a clear airway to prevent asphyxia (suffocation), as a blocked airway can lead to death within minutes [2]. Asphyxia occurs when the body is deprived of oxygen, often due to airway obstruction or trauma in accidents [t4][t8]. Once the airway is secured and breathing is assessed, the next steps involve managing circulation, which includes arresting haemorrhage and treating for shock [t1][t3]. While controlling severe bleeding is critical, it typically follows the immediate assessment of airway patency in standard trauma protocols to ensure the victim can breathe [t5][t6]. Therefore, treating asphyxia by clearing the airway is the essential first step in the life-saving sequence.
