Step-by-step explanation:
Every EMS system should have a coordinated network of emergency medical services that includes trained responders, ambulances, and medical equipment.
The system should also have protocols and guidelines in place for handling emergency situations, such as cardiac arrests, trauma incidents, and other medical emergencies.
For example, it is important for EMS systems to have automated external defibrillators (AEDs) readily available, as these devices are used for treating cardiac arrest by delivering an electric shock to restore a normal heart rhythm.
