What action should an EMD take if a caller becomes unresponsive?

When a caller becomes unresponsive, the proper course of action for an Emergency Medical Dispatcher (EMD) is to continue providing instructions and attempt to determine the cause of the unresponsiveness. This approach is critical because it allows the EMD to gather vital information about the situation, which can guide first responders in providing the necessary care upon arrival.

Remaining on the line while offering instructions may aid any bystanders who are present to take appropriate action, such as performing CPR or calling for help. Additionally, understanding why the caller became unresponsive can help in assessing potential medical emergencies or traumatic events that require immediate intervention.

Other responses, such as asking the caller to speak louder, would not assist in the situation if the caller is indeed unresponsive. Ending the call to focus on other emergencies would risk overlooking critical information about the unresponsive individual, compromising their care. Waiting for responders to arrive before acting would be inappropriate, as immediate action may be required to ensure the safety and survival of the individual in distress.
