Technology & Digital Tools Flashcards

Which type of radio communication system is standard among ski patrols for on-mountain coordination during a rescue?

Answer: VHF land mobile radio (LMR)

VHF land mobile radio systems are the industry standard for ski patrol communications because they offer reliable range, interoperability, and dedicated channels.

An automated external defibrillator (AED) gives a 'no shock advised' message. What does this indicate about the cardiac rhythm?

Answer: The rhythm is not shockable (e.g., asystole or PEA)

A 'no shock advised' message means the AED's algorithm detected a non-shockable rhythm such as asystole or pulseless electrical activity (PEA).

When relying on a smartphone for navigation in cold outdoor environments, what is the most common technology-related failure OEC providers should anticipate?

Answer: Battery failure due to cold temperatures

Lithium-ion batteries lose significant capacity in cold temperatures, making sudden smartphone shutdown the most frequent cold-weather technology failure.

Which digital tool provides OEC providers the most actionable avalanche hazard information before entering backcountry terrain?

Answer: Regional avalanche center forecast (e.g., avalanche.org)

Regional avalanche center forecasts provide danger ratings, avalanche problem types, and travel advice specifically for backcountry decision-making.

An OEC technician uses a capnography device in the field. A rising end-tidal CO2 (EtCO2) reading after BVM ventilation most likely indicates:

Answer: Return of effective circulation

A rising EtCO2 during resuscitation is one of the earliest indicators of ROSC (return of spontaneous circulation), reflecting increased pulmonary perfusion.

Dispatch receives a 911 call from a victim using an Apple Emergency SOS via satellite feature. What limitation must rescuers be aware of?

Answer: Location accuracy may be lower than standard GPS and messaging is text-only

Apple Emergency SOS via satellite uses low earth orbit satellites with text-relay to 911; location accuracy is lower than standard GPS and real-time voice calls are not supported.

An OEC provider uses a digital thermometer with a rectal probe for accurate core temperature measurement. Which temperature reading indicates severe hypothermia requiring aggressive rewarming?

Answer: Below 28°C (82.4°F)

Severe hypothermia is defined as a core temperature below 28°C (82.4°F), at which point cardiac dysrhythmias and loss of consciousness are likely.
