What does the acronym "C.A.B." stand for in CPR?

The acronym "C.A.B." stands for Circulation, Airway, Breathing, which is a critical sequence to follow when performing CPR. The rationale behind this order is based on the immediate needs of a person who is unresponsive and not breathing.

Initially focusing on Circulation involves performing chest compressions to circulate blood and maintain blood flow to vital organs, especially the brain and heart. This is crucial because brain damage can occur in just a few minutes without adequate blood flow. After that, ensuring the Airway is clear allows for effective rescue breaths if they are necessary. Finally, Breathing refers to the delivery of breaths to the victim if they are not breathing on their own.

This sequence prioritizes the most life-threatening issues first, aligning with emergency response protocols. Other combinations in the options diverge from this life-saving priority, emphasizing the importance of understanding and applying the correct sequence during CPR.
