What is the first step in the CABC's primary survey?

The first step in the CABC primary survey is to assess the patient's airway. This step is crucial because a clear airway is essential for effective breathing and oxygenation of the body. If the airway is obstructed, the patient cannot breathe properly, and this can quickly lead to life-threatening situations. By prioritizing the airway, responders can ensure that the patient receives adequate airflow, which can be vital in emergencies.

Once the airway is assessed and secured if necessary, other aspects of the primary survey can be addressed, such as checking breathing and evaluating circulation. Each element of the CABC survey builds upon the previous one, emphasizing the importance of the airway as the foundational step in patient assessment and management.
