What does the 'A' in the ABCs of CPR stand for?

The 'A' in the ABCs of CPR stands for Airway. This is a fundamental component of CPR because ensuring that a person's airway is clear is critical for effective rescue breathing and successful resuscitation. If the airway is obstructed, even if breathing is initiated, the person may not receive adequate oxygen, which can lead to further complications or death. Therefore, assessing and clearing the airway is the first step in the process before administering breaths or chest compressions.

Understanding the role of the airway in CPR highlights the importance of this initial step in emergency response, making it clear that effective CPR relies on ensuring the airway is open to allow air to reach the lungs.
