What is the first step in basic life support (BLS)?

The first step in basic life support (BLS) is assessing responsiveness and calling for help. This initial action is critical because it ensures that the person's condition is evaluated quickly, allowing the responder to determine if the person is unresponsive and in need of emergency assistance.

By checking for responsiveness, you can ascertain whether the individual is conscious or has a normal airway. If they are unresponsive, the next immediate step is to call for help, either by contacting emergency services or asking someone nearby to do so. This step is vital for ensuring that advanced medical care can be provided as soon as possible while you manage the situation.

After this assessment and call for help, the responder can move on to the next steps in the BLS protocol, which includes performing chest compressions and administering rescue breaths if necessary. The act of calling for help is essential in activating the emergency response system, which plays a crucial role in ensuring timely intervention for the victim.
