What is assessed during the 'Airway' check in a primary assessment?

During the 'Airway' check in a primary assessment, the focus is specifically on whether the airway is patent, meaning it is open and unobstructed, allowing for air to flow freely in and out of the lungs. This is a critical assessment step because a blocked airway can lead to hypoxia and is often a leading cause of death in emergencies. Ensuring that the airway is clear is paramount before addressing other concerns such as breathing and circulation.

Each of the other options addresses different aspects of the victim's condition: consciousness reflects neurological status, pulse indicates circulatory function, and adequate breathing assesses respiratory efficiency. While all these factors are vital in a complete primary assessment, the primary focus during the 'Airway' step is to confirm that air can reach the lungs unobstructed. This foundational check is essential for effective emergency management.
