In the context of CPR, the "C" in "CAB" stands for Compressions, which is a critical component of the resuscitation process. CAB refers to the order of actions recommended when performing CPR: Compressions, Airway, and Breathing.
Compressions are the first step because delivering high-quality chest compressions helps to circulate blood throughout the body, especially to vital organs like the brain and heart, increasing the chances of survival until advanced medical help arrives. These compressions should be performed at a rate of 100 to 120 per minute, at a depth of at least 2 inches for adults, and they should allow for full recoil of the chest between compressions to maximize blood flow.
Understanding that Compressions come first emphasizes the urgency and importance of quickly initiating chest compressions in a cardiac arrest situation, which is crucial for maintaining blood flow and preventing brain damage. This foundational concept in CPR training aligns with guidelines from organizations like the American Heart Association and is vital for effective emergency response.
