In the context of an unresponsive patient, what should the first step be?

In the context of an unresponsive patient, the first step should be to assess the airway. This is critical because an unresponsive individual may not be able to maintain their own airway, which could lead to airway obstruction and inadequate ventilation. If the airway is not opened and secured, any subsequent interventions, whether CPR or advanced medical support, could be ineffective or even harmful.

By assessing the airway, you are ensuring that the patient can breathe adequately, which is vital for oxygenation and preventing complications such as hypoxia. Once the airway is assessed and secured, appropriate measures can then follow, such as calling for advanced medical support, checking for a pulse, or providing CPR if needed. This step serves as the foundation for all other lifesaving interventions in an emergency scenario.
