OEC Technology & Digital Tools 3

Question 1

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

Accepted Answer

VHF land mobile radio (LMR)

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 3

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

Accepted Answer

Battery failure due to cold temperatures

Answer

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

Question 4

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

Accepted Answer

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

Answer

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

Question 5

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

Accepted Answer

Return of effective circulation

Answer

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