CH. 5 EMS COMMUNICATIONS Flashcards
assembly of radio equipment consisting of at least a transmitter, receiver, and antenna connection at a fixed location
base station
transmission of physiologic data, such as an ECG, from the patient to a distant point of reception
biotelemetry
low power portable radios that communicate through an interconnected series of repeater station cells
cellular telephones
a question that is specific and focused, demanding either yes or no answer or an answer chosen from specific options
close ended questions
the microwave transmission of digital signals through space or the atmosphere instead of transmission by radio waves
digital radio
to send to a specific destination or to send on a task
dispatch
radio system using more than one frequency to permit simultaneous transmission and reception
duplex
first aid instructions given by specifically trained dispatchers to callers over the telephone while an ambulance is en route to the call
emergency medical dispatch
a person who receives information and relays that information in an organized manner during an emergency
emergency medical dispatcher
a message put in code before it is transmitted
encoded
an emergency call in system in which additional information such as a phone number and location of the caller is recoded automatically through sophisticated telephone technology and the dispatcher need only confirm the information on the screen
enhanced 911 system
the federal agency that has jurisdiction over the interstate and international telephone and telegraph services and satellite communications, all of which may involve EMS activity
Federal Communications Commission (FCC)
in radio communications, the number of cycles per second of a signal; inversely related to wavelength
frequency
unit of frequency equal to 1 cycle per second
hertz (Hz)
the exchange of information between two or more persons
interpersonal communications
communication system linked by wires, usually in reference to a conventional telephone system
landline
method by simultaneous transmission of voice and ECG signals can be achieved over a single radio frequency
multiplex
in radio communications, interference in a radio signal
noise
a question that does not have a yes or no answer, and that does not give the patient specific options form which to choose
open ended question
a group of disorders that cause delays in many areas of childhood development, such as the development of skills to communicate and interact socially, and may include repetitive body movements and difficulty with changes in routine; includes autism and Asperger’s syndrome, among others
pervasive development disorders (PDDs)
a terminal that receives transmissions of telemetry and voice from the field and transmits messages back, usually through the base station
remote console
miniture transmitter that picks up a radio signal and rebroadcasts it, extending the range of a radio communications system
repeater
method of communication using a single frequency that enables transmission reception of voice or an ECG signal that is incapable of simultaneous transmission and reception
simplex
a radio code system using the number 10 plus another number
ten-code
communicating with the patient
therapeutic communication
a radio transmitter and receiver housed in a single unit; a two way radio
transceiver
sharing of radio frequencies by multiple agencies or systems
trunking
the portion of the radio frequency spectrum between 300 and 3000 mHz
UHF
the portion of the radio frequency spectrum between 30 and 150 mHz
VHF
the distance in a propagating wave from one point to the corresponding point on the next wave
wavelength
