Chapter 4 Communications & Documentation Flashcards
A low-power radio that communicates through an interconnected series of repeater stations called “cells”.
cellular telephone
A process in which electronic signals are converted into coded, audible signals; these signals can then be transmitted by radio or telephone to a receiver with a decoder at the hospital.
telemetry
VHF and UHF channels that the Federal Communications Commission has designated exclusively for EMS use.
MED channels
Written documents, signed by the EMS system’s medical director, that outline specific directions, permissions, and sometimes prohibitions regarding patient care; also called protocols.
standing orders
A special base station that receives messages and signals on one frequency and then automatically retransmits them on a second frequency.
repeater
Single frequency radio; transmissions can occur in either direction but not simultaneously in both; when one party transmits, the other can only receive, and the party that is transmitting is unable to receive.
simplex
A radio frequency that searches several frequencies until the message is completed; the process is then repeated.
scanner
Radio frequencies between 300 and 3,000 MHz.
UHF (ultra-high frequency
Anything that dampens or obscures the true meaning of a message.
noise
The written portion of the EMT’s patient interaction. This becomes part of the patient’s permanent medical record.
documentation
A special telephone line that is used for specific point-to-point communications; also known as a “hotline”.
dedicated line
The study of space between people and its effects on communication.
proxemics
Questions for which the patient must provide detail to give an answer.
open-ended questions
The legal document used to record all patient care activities. This report has direct patient care functions but also administrative and quality control functions. They are also known as prehospital care reports.
patient care report (PCR)
Telecommunication systems that allow a computer to maximize utilization of a group of frequencies.
