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

The acronym C-A-B stands for Compression, Airway, and Breathing, which represents the essential steps to take when performing cardiopulmonary resuscitation (CPR) on an unresponsive individual who is not breathing normally.

The correct sequence emphasizes the importance of starting with chest compressions, as they help to circulate blood, maintaining blood flow to vital organs, especially the brain and heart. This approach is critical, especially in emergency situations, as it ensures that the person receives immediate help while waiting for professional medical assistance. After initiating compressions, the rescuer then checks and secures the airway before providing rescue breaths.

Understanding this sequence is vital for effective CPR, as it reflects current guidelines established by health organizations worldwide, which emphasize the priority of compressions to improve survival outcomes in cardiac arrest cases.

In contrast, the other choices do not accurately represent the most effective sequence or terminology used in contemporary CPR training. Hence, the correct answer aptly captures the intended methodology for performing CPR effectively.
