EMS Communications Flashcards

Which DOES NOT constitute a method of safeguarding the patient's privacy when information is transmitted?

Answer: Use 10-code system

Using a 10-code system is a method of brevity and standardization in radio communication, not a primary method for safeguarding patient privacy. While it can obscure some details, it doesn't inherently protect identifiable health information. Safeguarding privacy involves avoiding patient names, using secure communication channels like telephones for sensitive data, and turning off external speakers to prevent eavesdropping, aligning with HIPAA regulations.

What is the normal two-way radio mobile range?

Answer: 10-15 miles

The typical effective range for a mobile two-way radio (vehicle-mounted) operating in a relatively flat, unobstructed environment is generally 10-15 miles. This range can be influenced by terrain, obstructions, antenna type, and power output, but 10-15 miles is a common practical estimate for reliable communication.

What is a gadget that receives a low-power portable radio transmission on one frequency and sends it out again on a different frequency with a larger power?

Answer: Repeater

A repeater is an electronic device that receives a radio signal and retransmits it at a higher power or on a different frequency, extending the range and improving the clarity of radio communications. This is crucial in EMS for maintaining communication over large areas, through obstructions, or with low-power portable radios.

How long should you wait to start speaking after pressing the transmit button?

Answer: 1 second

It is standard radio etiquette to wait approximately one second after pressing the transmit button before speaking. This brief pause ensures that the radio's transmitter is fully engaged and the signal is stable, preventing the loss of the first few words of your message and ensuring clear communication.

When a medical emergency arises, who is in charge of allocating emergency medical resources?

Answer: Emergency medical dispatcher

The Emergency Medical Dispatcher (EMD) is specifically trained and responsible for receiving emergency calls, providing pre-arrival instructions, and allocating appropriate emergency medical resources (ambulances, paramedics, fire units) based on the nature and severity of the reported incident. They are the crucial link between the public and the EMS system.

What information must a caller give the dispatcher first?

Answer: Name and call-back number

While the nature of the event and location are critical, dispatchers are trained to first obtain the caller's name and call-back number. This ensures that if the call is disconnected, the dispatcher can re-establish contact, which is vital for gathering further information or providing updates. This is a standard protocol in emergency communications.

How much telemetry can you typically broadcast when transmitting en route?

Answer: 15- to 20-seconds

When transmitting telemetry en route to the hospital, it's generally recommended to keep transmissions concise, typically around 15-20 seconds. This allows for the efficient transfer of critical physiological data (like ECGs) without monopolizing the radio channel, ensuring other units can communicate and maintaining brevity in a busy system.

If the paramedic receives improper directions, what should they do?

Answer: Question them

If a paramedic receives directions that seem improper, unsafe, or unclear, they have a professional and ethical obligation to question them. Following improper directions could jeopardize patient safety, rescuer safety, or the success of the mission. It's crucial to seek clarification or alternative instructions rather than blindly proceeding.

What has made it possible for the paramedic to submit 12-lead ECGs to the hospital while still on the scene?

Answer: Cellular technology

Cellular technology, specifically the advancements in mobile data transmission, has revolutionized prehospital care by enabling paramedics to transmit 12-lead ECGs and other physiological data directly from the scene to the hospital. This allows for early diagnosis of conditions like STEMI and facilitates rapid activation of cardiac cath labs, significantly improving patient outcomes.

What steps are involved in sending physiological data over a distance?

Answer: Biotelemetry

Biotelemetry is the process of remotely measuring and transmitting vital signs and other physiological data from a living organism. In EMS, this refers to the transmission of patient data, such as ECGs, blood pressure, and oxygen saturation, from the ambulance or scene to the receiving hospital over a distance.

What term best reflects the method of combining all accessible frequencies and employing them according to first come, first serve?

Answer: Trunking

Trunking is a radio system technology that efficiently shares a limited number of radio channels among a large group of users. When a user needs to transmit, the system automatically assigns an available channel on a 'first come, first served' basis, rather than assigning a dedicated channel to each user. This optimizes channel usage and improves communication efficiency.

What action does a typical EMS response take as soon as an accident is detected?

Answer: Notification and response

The immediate actions following the detection of an accident in an EMS system are notification (dispatch receiving the call and alerting units) and response (EMS units immediately mobilizing and traveling to the scene). Treatment and transport occur after arrival, and preparation for the next event is a post-incident activity.

Which is not required to be communicated to the medical control doctor in an emergency situation?

Answer: Exact location of the incident

While the general location is known to dispatch and the responding crew, the *exact* street address or precise coordinates of the incident are typically not a required detail to communicate to medical control during a patient report. Medical control focuses on patient assessment, treatment, and transport decisions, not on navigating to the scene.

Which form of transmission allows for simultaneous transmission and reception?

Answer: Simplex

Duplex transmission allows for simultaneous two-way communication, meaning both parties can transmit and receive at the same time, similar to a telephone conversation. Simplex, on the other hand, allows only one party to transmit at a time, requiring users to take turns speaking.

What is the base station's typical power output?

Answer: 45-275 watts

Base stations, which are fixed radio transmitters, typically have a significantly higher power output than mobile or portable radios to ensure wide coverage. A common range for EMS base stations is 45-275 watts, allowing them to effectively communicate with units across a broad service area.

The following are all included in EMS transmissions, EXCEPT:

Answer: online medical control with base station physician

EMS transmissions encompass the entire communication process from the initial call to patient handoff. While online medical control with a base station physician is a critical component of patient care communication, it is a *specific type* of interaction that occurs *during* an incident. The other options – computer-aided dispatch (CAD), emergency medical dispatcher, and a citizen notifier – represent the fundamental *components and origins* of the broader EMS transmission *system* that initiates and manages the overall response.
