This is a good question. Just as the name would imply, an EMT is an Emergency Medical Technician. They are generally the first responders to an emergency situation via ambulance or sometime helicopter depending on the situation and nature and location of the emergency. They are the ones who are generally responsible for being able to stabilize a patient for transport to the nearest medical facility based on need and injury type. They can start iv lines if needed, and depending on training can administer certain meds as would be the case if there was an over dose call and the patient were in need of Narcan. Basic emergency training and some first aid and medical training are needed in order to become an EMT.
