Of the following, which is NOT one of the ABC's of first aid?

The ABC's of first aid refer to a systematic approach in emergency situations to ensure that a victim's vital functions are assessed and treated effectively. The acronym encompasses three critical components: Airway, Breathing, and Circulation.

Airway involves ensuring that the victim's airway is open and clear, which is crucial for effective breathing. Breathing refers to checking if the victim is breathing adequately and, if not, performing the necessary actions to assist with respiration. Circulation focuses on assessing the victim's blood flow and ensuring that their heart is functioning properly to maintain oxygen delivery to vital organs.

The option that does not fit into this framework is related to emergency transport, which is the role of an ambulance. While ambulances are essential for transporting injured individuals to medical facilities, they are not part of the immediate first aid steps involved in the ABC's. Therefore, the correct answer highlights that "Ambulance" does not belong to the foundational principles of first aid practiced in urgent situations.
