What is the function of an emergency medical dispatch (EMD) system?

The function of an emergency medical dispatch (EMD) system is to assist dispatchers in selecting appropriate response units and offering instructions to callers in emergency situations. This system evaluates the nature of the emergency and determines the level of response required, ensuring that the most suitable resources are dispatched based on the specific circumstances. Additionally, the EMD provides pre-arrival instructions to callers, which can be crucial in managing a medical emergency before help arrives. This includes giving life-saving instructions, such as how to perform CPR or control bleeding, which empowers bystanders to make a meaningful impact in stabilizing the patient until emergency services arrive. By facilitating these critical actions, the EMD system plays a vital role in improving patient outcomes during emergencies.
