Paramedic
People often use the term "paramedic" for anyone who works on an ambulance. However, not all ambulances have paramedic on board. "Emergency Medical Technicians" (EMTs) or "Emergency Care Assistants" (ECAs) do similar work but have less training. Some ambulances also have doctors and nurses. In many countries, the title of "paramedic" is for those who have taken a specific training course.
