What initial step should be taken following the recognition of an unresponsive child?

Following the recognition of an unresponsive child, the initial step is to activate the emergency response system. This is crucial because it ensures that help is on the way while you begin essential life-saving measures. The activation of the emergency response system connects the situation to advanced medical resources, which can provide necessary support and interventions as quickly as possible.

By calling for help, you also establish a plan for resuscitation efforts, particularly if you're alone. Once you have activated the emergency response, you can then move on to check for breathing and provide other interventions, if necessary. This sequence of actions is aligned with emergency protocols and ensures that professional help is being summoned without delay, securing the best possible outcome for the child.
