What is the first step in the BLS sequence for responding to an adult victim who is unresponsive?

The first step in the BLS sequence for responding to an unresponsive adult victim is to check for responsiveness and call for help. This initial action is crucial because it allows the responder to assess the situation and determine if the person is truly unresponsive. Checking for responsiveness typically involves gently shaking the person and asking if they are okay. If there is no response, it indicates that the individual may require immediate assistance.

Calling for help is equally important, as it ensures that emergency services are alerted and on their way to provide advanced care. This step sets the stage for the rest of the BLS process, including assessing breathing, starting chest compressions if needed, and providing other necessary interventions. By establishing that help is on the way while simultaneously checking for responsiveness, the responder creates a coordinated approach to care for the victim effectively.

Additional steps, such as checking for breathing or ensuring a safe environment, are vital but follow after confirming unresponsiveness and calling for assistance. Starting chest compressions immediately is also critical, but it should only be done after assessing responsiveness and ensuring that emergency services have been summoned.
