Semantic
meaning of words
Technical
communications hardware
Communication
mutual language
What type of communication system uses a computer to route transmissions to the first available frequency?
Trunked
What technique is effective in helping the dispatcher get information from a distressed caller?
A standard set of medically approved questions
Which is not a guideline for effective radio use?
Use codes that are part of the international EMS system.
The dispatcher’s directions to the caller for appropriate emergency measures are known as
Prearrival instructions
How can AACN improve outcomes with seriously injured patients?
Assisting with field triage destination & transportation decisions
What is the last step in the sequence of communications during an EMS response
Transferring communications
Systems that transmit and receive on the same frequency are known as what type
Simplex
Which radio wave can penetrate through concrete and steel most effectively?
UHF
The main duties of the dispatcher, after sending the responders and providing prearrival instructions, include
Supporting & coordinating
The practice of notifying a receiving hospital of an ambulance’s impending arrival began in the
1970s
What is the best explanation for the need to communicate effectively with other incoming EMS practitioners when you’re on the scene with a critical patient
To coordinate and implement a treatment plan
The federal agency that controls and regulates nongovernmental communications is the
FCC
Utilizing specialized terms, abbreviations, or codes for radio use enhances communications by
Shortening airtime and transmitting thoughts quickly
The process of interrogating callers with medical questions to elicit information and then determine the proper level of response is known as
Priority dispatching
Health organizations are responding to the rise of VOIP phones and the ability to send photos, videos, and text messages from mobile devices via the Internet with
an initiative called Next Generation 911 (NG-911)
Although the use of smartphones as a communication device in EMS is expanding rapidly, what is one limitation of smartphone use versus traditional radios utilizing radio frequencies?
Radios can easily send voice messages to many recipients simultaneously, whereas smartphones are not as adept at it
National Emergency Medical Services Information System (NEMSIS) =
Data dictionary
Public safety answering point (PSAP)=
any agency that takes emergency calls from citizens in a given region & dispatches emergency resources necessary to respond to call
10-code
radio communication system using codes that begin w/ the word ten
Safecom
communications program of the US Department of Homeland Security that provides research & guidance tp emergency response agencies regarding the development of interoperable com/ systems
“Doctor Strong” in com w/ hospital
to alert the ED staff of uncooperative/ potentially violent PT
Echo procedure
immediately repeating each transmission received during radio com/s to ensure it was accurately received
Command presence
taking charge of an incident in an authoritative manner, including communicating, delegating tasks, & coordinating the scene
Enhanced 911 (E911)
emergency 911 call system in which com/ center computers display the caller’s number & location
Automatic number identification (ADI)
in computers at E911 com centers, the ability to display caller’s number
Automatic location identification (ALI)
in computers at E911 com centers, the ability to display caller’s location
Automatic Crash Notification (ACN)
data collection & transmission system that can automatically contact a national call center on local public safety answering point & transmit limited specific crash data, EX where the crash is
call routing
process of transferring a emergency call to the nearest 911 center; occasionally technical problems cause such a call to be routed out of the call area
Federal Communication Commision (FCC)
agency that controls all nongovernmental com/s in US
Voice over Internet Protocol(VoIP)=
tech/ that provides voice com/s through internet access from a computer/ mobile device
Advanced automatic crash notification(AACN)=
data collection & transmission system that can automatically contact a national call center/local public safety answering point & transmit detailed crash data
Accelerometers
sensor in vehicle that measures a change in total velocity, forces applied to vehicle, direction of forces were applied, whether vehicle rolled, air bag deployment, & final resting position
Repeaters
electronic device that receives a signal & rebroadcasts it at a higher power
Simplex transmissions
Transmit & receive on the same frequency thus cannot do both simultaneously. After you transmit a message, you must release the transmit button & wait for response
Duplex transmissions
allow simultaneous two-way com/s by using 2 frequencies for each channel. Each radio must be able to transmit and receive on each channel.
Multiplex systems
are duplex systems with the additional capability of transmitting voice & data simultaneously. This enables you to carry on a conversation w/ the EMS physician while you are transmitting an ECG strip.
Trunking=
com/s system that pools all frequencies & routes transmissions to the next available frequency
Multiband radio
type of radio/system that combines a wide range of radio bands allowing services to operate on different bands
Cognitive radio
Like trunked radios, it can pick an open, strong frequency w/o the user knowing which one was selected but knowing that they are talking to Hospital A. it has the ability to combine all of these features & program them w/ additional operational guidelines
Dead spots
where com/s transmission & reception are poor
Common operating Picture (COP)
single display of operational info, such as data from a crash & an emergency responds to it, that is simultaneously shared by all units involved in responding to the emergency so that those working it get all the same info
geographic information system (GIS)
information system that stores & analyzes info about or within a specific geographic area for the purpose of aiding decision making within a org/ or group for which specific GIS has been developed
Ad Doc database
each time a PT is encountered Multiple vital signs, video, electronic health record, & voice-to-text translation of medic findings will be pushed to those databases & parked until the intended recipient is able to review them.
Information Communication Technology (ICT)
concept that unifies traditional com/s tech/ (CT) systems & info tech/ (IT) systems to provide access to & use of info/.
FCC established the Public Safety and Homeland Security Bureau to handle public safety issues. The FCC’s primary functions include:
Licensing and allocating radio frequencies
Establishing tech standards for radio equipment
Licensing & regulating the technicians who repair & operate radio equipment
Monitoring frequencies to ensure appropriate usage
Spot-checking base stations & dispatch centers for appropriate licenses & records
