What should be done after calling 911 in the event of a medical emergency?

Controlling access to the scene is crucial after calling 911 in a medical emergency because it helps ensure safety for both the injured person and rescuers. By managing who can enter the area, you can prevent bystanders from interfering with medical personnel or from adding to the chaos of the situation. This control can also assist in keeping the scene clear for emergency responders when they arrive, allowing them to work effectively and efficiently without additional distractions or obstacles.

While starting first aid may seem immediate and necessary, it is essential to ensure that the scene is safe and that you are not inadvertently putting yourself or others at risk. Waiting for nearby staff can be beneficial, but in an emergency, acting quickly and effectively is usually necessary. Attempting to diagnose the situation may delay critical first aid or proper care; the focus should be on providing immediate assistance as needed, rather than trying to assess the injury or cause of the emergency. Therefore, controlling access effectively lays the groundwork for a safer and more organized response to the emergency.
