What does CAB stand for in first aid?

CAB stands for Circulation, Airway, Breathing, which is a crucial sequence to follow in emergency situations when assessing a patient's condition. In first aid, the primary focus is to restore and maintain blood circulation before addressing the airway and breathing. This order reflects the understanding that effective circulation is vital for oxygen delivery to the tissues and organs, which is essential for survival.

When performing CPR, for example, rescuers first check if the patient has a pulse to assess circulation. If there is no pulse, the next step is to initiate chest compressions to restore blood flow. Following this, the rescuer should ensure the airway is clear and then provide rescue breaths if necessary. This structured approach ensures that the most immediate life-threatening issues are addressed in the right order, maximizing the chance of a positive outcome for the victim. Understanding this sequence is fundamental in first aid training and practice.
