What does CAB stand for in the context of CPR?

In the context of CPR, CAB stands for Circulation, Airway, Breathing, which reflects the critical priorities in responding to a cardiac emergency. This sequence emphasizes the importance of restoring circulation through chest compressions before addressing the airway and breathing.

Focusing on circulation first is vital because the primary goal in a life-threatening situation, such as cardiac arrest, is to maintain blood flow to vital organs, especially the brain and heart. Chest compressions help generate blood flow, which is crucial as it keeps oxygen and nutrients available to these organs while you prepare to manage the airway.

Following circulation, the airway must be checked and cleared to ensure that any obstructions are removed. This step is essential to allow for effective rescue breaths if necessary.

Finally, breathing, which involves providing breaths to the patient, is the last component in the sequence. This order ensures that the most immediate threat to life—lack of blood circulation—is addressed first, providing the best chance for survival.

Understanding the CAB sequence is a fundamental component of CPR training as it guides responders on the most effective way to assist someone in a critical situation.
