What is indicated by the 'B' in the CPR ABCs?

In the context of the CPR ABCs, the 'B' stands for Breathing. This is a critical component in emergency care, as maintaining an airway and ensuring that a person is breathing effectively is essential for their survival. In CPR, the sequence is to first check for responsiveness, then establish whether there is normal breathing. If not, rescuers are trained to provide rescue breaths as necessary to help oxygenate the person's blood.

Understanding the ABCs of CPR is vital for effective emergency response. The process emphasizes checking for airway (A), breathing (B), and circulation (C). Each component plays a distinct role in the assessment and support of a person in a life-threatening situation. Therefore, recognizing 'Breathing' as the correct answer highlights its significant role in ensuring that the victim can receive adequate oxygenation during an emergency scenario.
