When should you activate emergency medical services (EMS)?

Activating emergency medical services (EMS) is crucial when a situation is suspected to be life-threatening. This allows for immediate access to advanced medical care that may be necessary for the individual in distress. Recognizing signs of a life-threatening condition—such as severe bleeding, difficulty breathing, unresponsiveness, or signs of a heart attack—should prompt an immediate call for EMS. Quick intervention can significantly improve outcomes in emergencies.

Delaying the activation of EMS—whether it be for personal assessment or providing care—is not advisable in serious situations, as timely advanced medical support can be lifesaving. Therefore, the appropriate action is to activate EMS at the first indication that a situation could be critical, ensuring that professional help is on the way while you attend to the patient.
