In the context of cardiopulmonary resuscitation (CPR), what does "CAB" stand for?

In the context of cardiopulmonary resuscitation (CPR), "CAB" stands for Circulation, Airway, Breathing. This acronym reflects the sequence of steps that are most critical in managing a patient in cardiac arrest.

The first step, "Circulation," emphasizes the need for immediate chest compressions to restore blood flow to vital organs. This is a crucial change in CPR guidelines that prioritizes circulation over ventilation. The next step is "Airway," which involves ensuring that the airway is clear and open, allowing for effective breathing if rescue breaths are necessary. Finally, "Breathing" refers to providing rescue breaths if the patient is unresponsive and not breathing adequately.

This sequence of steps is especially important as it is designed to maximize the chances of survival and recovery in a cardiac arrest scenario. It directs responders to take immediate action that stimulates blood circulation, which is vital for maintaining organ function and preventing irreversible brain damage.
