What should be done first when treating a heart attack?

When treating a heart attack, the initial step should be to assess responsiveness. This is crucial because it allows the responder to understand the severity of the situation and determine the appropriate next steps. Assessing responsiveness helps identify whether the person is conscious or unconscious, which significantly influences the care needed. If the person is responsive, they can provide vital information, and the responder can proceed with more targeted assistance, such as reassuring the individual and aiding in their comfort until help arrives.

Establishing if the individual is unresponsive is key in deciding whether CPR or other interventions are necessary. For someone who is unresponsive, immediate action would revolve around calling for emergency medical services and potentially initiating CPR. Therefore, assessing responsiveness lays the groundwork for the entire emergency response process. This evaluation informs how to proceed with treatment and ensures that actions taken are appropriate for the individual's condition.
