Chapter 5 Flashcards
(30 cards)
Biotelemetry
Transmission of physiologic data, such as an ECG, from the patient to a distant point of reception (aka telemetry)
Base station
Assembly of radio equipment consisting of at least a transmitter, receiver, and antenna connection at a fixed location
Cellular telephones
Low-powered portable radios that communicate through an interconnected series of repeater stations called “cells”
Closed-ended question
A question that is specific and focused, demanding either a yes or no answer or an answer chosen from specific options
Digital radio
The microwave transmission of digital signals through space or the atmosphere instead of transmission by radio waves
dispatch
To send to a specific destination or to send on a task
Duplex
Radio system using more than one frequency to permit simultaneous transmission and reception
Emergency medical dispatch
First aid instructions given by specially trained dispatchers to callers over the telephone while an ambulance is en route to the call
Emergency medical dispatcher (EMD)
A person who receives information and relays that information in an organized manner during the emergency
Encoded
A message is out into a code before it is transmitted
Enhanced 9-1-1 system
An emergency call-in system in which additional information such as the phone number and location of the caller is recorded automatically through sophisticated telephone technology and and the dispatcher need only confirm the information on the screen
Federal Communications Commission (FCC)
The federal agency that has jurisdiction over interstate and international telephone and telegraph services and satellite communications, all of which may involve EMS activity
Frequency
In radio communications, the number of cycles per second of a signal; inversely related to the wavelength
Hertz (Hz)
Unit of frequency equal to 1 cycle per second
Interpersonal communications
The exchange of information between two or more persons
Landline
Communications system linked by wires, usually in reference to a conventional telephone system
Multiplex
Method by which simultaneous transmission of voice and ECG signals can be achieved over a single radio frequency
Noise
In radio communications, interference in a radio signal
Open-ended-question
A question that does not have a yes or no answer, and that does not give the patient specific options from which to choose
Pervasive developmental disorders (PDDs)
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 Aspergers syndrome, among others
Remote console
A terminal that receives transmissions of telemetry and voice from the field and transmits messages back, usually through the base station
repeater
Miniature transmitter that picks up a radio signal and rebroadcasts it, extending the range of a radio communications system
Simplex
Method of radio communication using a single frequency that enables transmission reception of voice or an ECG signal but is incapable of simultaneous transmission and reception
Ten-code
A radio code system using the number 10 plus another number
