Introduction
• In EMS, person-to-person communication, face-
to-face, telephone, voice radio dialogue, cycles of
telemetry data use, handwritten records
– Lag in development of EMS communications
technology.

Effective Communications
• Emergency medical dispatcher (EMD): manages
entire system of EMS response and readiness.
• Patient, family, bystanders, others
• Personnel from responding agencies (police, fire
department, mutual aid ambulances)
Copyright © 2017, 2013, 2009 Pearson Education, Inc. All Rights Reserved.
Bryan E. BledsoeRichard A. Cherry Robert S. Porter
Effective Communications
• Health care staff: physicians' offices, health care
facilities, nursing homes.
• Medical direction physician: interprets patient
findings; makes medical decisions.
– You must interact effectively with everyone involved in
the call.
– EMS is ultimate team endeavor.

Basic Communication Model
• Communication: exchanging information between
individuals.
– Language includes words, numbers, symbols, special
codes.
– Encode message; select medium for sending it.
– Receiver must decode and understand message and
give feedback.
