Emergency medical services make up the majority of the calls that most fire departments including St. Johnsbury respond to.  The fire department acts as first responders to any medical emergency in the village area of town.  Calex Ambulance is the local EMS agency and provides transport and paramedic are to the patients.  With the fire department responding first it provides the patient with much better and prompt emergency care.  The on duty crew will respond with an engine, assess the patient which includes taking pluses, blood pressures and assessing breathing.  The crew will also find out exactly what the problem is and can then relay that information to the responding ambulance.

To allow the fire department to give this service to the community each full time firefighter must become certified as an Emergency Medical Technician (EMT) at the Basic level.  Some of the members have expanded their training to the Intermediate level allowing even more advanced care to be given.
