CHAPTER 5: COMMUNICATIONS Flashcards
COMMUNICATION LOOP
SENDER
MESSAGE TRANSMISSION
RECEIVER
FEEDBACK
BASE STATION
FIXED LOCATION, MOST POWERFUL RADIOS, CAPABLE OF OPERATING ON MULTIPLE FREQUENCIES AND BANDS
MOBILE TRANSCEIVERS
MOUNTED IN VEHICLES AND RELIES ON VEHICLE’S POWER SYSTEM
PORTABLE TRANSCEIVERS
SMALL, BATTERY POWERED UNITS (WALKIE TALKIES)
SIMPLEX RADIO
MOST BASIC TYPE, ALL TRANSMISSIONS OCCUR ON SAME FREQUENCY, RESTRICTED TO LINE OF SIGHT/SHORT RANGE
DUPLEX
UTILIZES PAIR OF FREQUENCIES
TRANSMITTED ON ONE FREQUENCY AND RECEIVED ON SECOND FREQUENCY
ALLOWS COMMUNICATIONS IN ONLY ONE DIRECTION AT A TIME
USES REPEATERS
MULTIPLEX
USES RADIO SIGNALS TO CARRY MULTIPLE AUDIO STREAMS AT THE SAME TIME
DIGITAL RADIO
ALLOWS TRANSMISSION OF DIGITAL (COMPUTER) OR ANALOG (VOICE) THAT HAVE BEEN COMPRESSED BY A COMPUTER
REPEATERS
SPECIALIZED BASE STATION TRANSCEIVER THAT ALLOWS RADIO SYSTEM TO COVER A MUCH LARGER AREA AND BYPASS OBSTRUCTIONS
DIGITAL TRUNKED RADIO SYSTEMS
USE MULTIPLE REPEATERS AND COMPUTERS TO ROUTE RADIO TRAFFIC WITHIN THE SYSTEM, OPERATE ON 800 AND 900MHZ UHF BANDS
RADIO DEAD SPOTS
AREAS WHERE MOBILE/PORTABLE RADIOS CANNOT COMMUNICATE WITH REPEATERS OR EACH OTHER
PHASES OF EMERGENCY MEDICAL DISPATCH (5)
INITIAL RECEIPT OF 911 CALL
INFORMATION GATHERING
DISPATCH UNITS
ADVICE TO CALLER
ONGOING COMMS WITH FIELD UNITS
RADIO WAVES
ELECTROMAGNETIC RADIATION THAT MAY BE ENCODED TO TRANSMIT A WIDE VARIETY OF INFORMATION
RADIO FREQUENCIES
NUMBER OF OSCILLATIONS PER SECOND OF THE CARRIER WAVE, MEASURED IN HERTZ
FEDERAL COMMUNICATIONS COMMISSION
GROUP FREQUENCIES INTO BANDS AND ASSIGNS EACH BAND FOR SPECIFIC PURPOSE
WHAT FREQUENCIES DO EMS AND PUBLIC SAFETY COMMS OPERATE ON (2)
VERY HIGH FREQUENCY (VHF) BAND AND ULTRA HIGH FREQUENCY (UHF) BAND
BIOTELEMETRY
MEASUREMENT AND TRANSMISSION OF VITAL SIGNS AND OTHER PHYSIOLOGIC DATA TO A REMOTE TERMINAL
TELEMEDICINE
SPECIALIZED COMPUTER TERMINALS THAT ALLOW TWO-WAY TRANSMISSION OF SOUND, VIDEO, VITAL SIGNS, EKG, AND OTHE DIAGNOSTIC DATA FOR INTERACTIVE EXCHANGE OF INFO BETWEEN MEDIC AND MEDICAL CONTROL
PHASES OF COMMUNICATION FOR EMS RESPONSE (4)
DISPATCH
RESPONSE TO SCENE
ON-SCENE AND TACTICAL

HEAD-TO-TOE FINDINGS
EKG FINDINGS
TREATMENT GIVEN SO FAR AND RESPONSE
INTERVIEWING STRATEGIES (9)
REFLECTION, EMPATHY, CONFRONTATION, FACILITATION, SILENCE, CLARIFICATION, REDIRECTION, SIMPLIFICATION, SUMMARIZATION
CULTURAL COMPETENCE
UNDERSTANDING HOW A PERSON’S CULTURAL INFLUENCES AFFECT HOW THEY BEHAVE AND REACT TO STRESSFUL SITUATIONS AND USING THAT TO CHOOSE THE WAY YOU INTERACT
INTERVIEWING CONSIDERATIONS IN CROSS-CULTURAL COMMUNICATIONS AND WHO THEY OFFEND (7)
EYE CONTACT (NATIVES, ASIANS, AFRICANS)
TOUCHING WITH LEFT HAND (ISLAMIC AND HINDU)
TOUCHING THE HEAD (ASIAN)
TOUCHING FEET (MUSLIMS AND THAIS)
HANDS ON HIPS (MEXICANS, ARGENTINIANS)
NODDING (DIFFERENT IN ASIAN CULTURES)
HAND GESTURES
SQUELCH
FILTERING SYSTEM TO BLOCK OUT BACKGROUND NOISE BUT STILL ALLOWS RADIO SIGNALS TO BE HEARD
