5 Emergency Decision-Making Practice Cases

Purpose and limits

Individual trauma field triage is different from mass-casualty triage. These cases concern EMS decision-making and are not stand-alone treatment protocols. Work within training, scope of practice, medical direction, and local procedures.

A practical decision sequence

1. Make the scene safe and identify how many patients need care.

2. Use a systematic primary assessment to identify and address immediate threats. Provide interventions within scope and protocol, but do not let nonessential procedures delay transport of an unstable patient.

3. Reassess after interventions and during transport. Changes in mental status, breathing, circulation, or vital signs can change both urgency and destination.

4. Decide transport priority and destination separately. Priority reflects how urgently the patient needs transport; destination reflects which facility can provide the needed care within the regional system.

Consider the patient's condition, facility capability, distance, system capacity, and local rules when selecting a destination. National model guidelines are intended to inform, not replace, local protocols.

Blunt trauma with signs of shock

A 28-year-old driver is removed from a high-speed crash. The patient is pale and confused, has a weak rapid pulse and low blood pressure, and has a deformed pelvis. No major external bleeding is visible.

Treat this as an immediately life-threatening injury. Address catastrophic bleeding if present, support airway and breathing as needed, minimize heat loss, and provide other indicated interventions within protocol. Request additional resources if they can help without delaying departure, and notify the receiving facility early.

Transport at the highest urgency. Abnormal mental status and circulation, together with suspected serious injury, indicate high risk. Transport promptly to the highest appropriate trauma-care level available in the regional system, following local field-triage and bypass rules. Do not assume that the nearest facility is the best destination solely because it is closest.

Head injury after a fall

A 76-year-old taking an anticoagulant fell from standing and struck their head. They are awake and initially answer questions, report a headache, and have currently stable vital signs with no obvious external injury.

Do not dismiss the event as minor because the fall was low-energy or the first assessment is reassuring. Establish the timeline, medication and medical history; assess mental status and signs of head injury; and repeat assessments for deterioration. Provide supportive care and minimize unnecessary movement when indicated.

Arrange prompt transport for evaluation. Use local field-triage criteria and destination protocols to select a hospital capable of assessing the suspected injury. If mental status worsens or high-risk criteria are present, escalate destination and urgency accordingly. A mechanism or special consideration can raise concern, but destination depends on the full clinical picture and regional system.

Sudden speech difficulty and arm weakness

A 67-year-old develops sudden difficulty speaking and weakness on one side. A family member reports that the patient was last known well at 14:10. The patient is alert but has trouble following some instructions.

Suspect stroke. Record the last-known-well time as accurately as possible, perform the approved stroke assessment, check glucose if available under protocol, and monitor airway, breathing, circulation, and mental status. Communicate findings and timing to the receiving facility. Avoid delays for tasks that do not change immediate care.

Treat transport as time-critical and follow the regional stroke-triage pathway. Destination may depend on stroke severity, travel time, hospital capabilities, and how reliably the system can transfer patients for advanced treatment. Current AHA guidance emphasizes local system characteristics when selecting a destination, including consideration of the closest thrombectomy-capable hospital where rapid transfer pathways are not functioning well.

Severe breathing difficulty after allergen exposure

A 34-year-old develops widespread hives, facial swelling, noisy breathing, and light-headedness shortly after eating a food they may be allergic to. They become increasingly anxious and can speak only a few words at a time.

Treat this as a rapidly worsening airway and breathing emergency. Request advanced support if available, provide airway and breathing support, and administer indicated emergency treatment within scope and local protocol. Reassess continuously; apparent early improvement does not remove the need for evaluation and transport.

Arrange immediate, high-priority transport to an emergency department capable of managing airway emergencies. Give an early report so the receiving team can prepare. The destination decision is not simply a matter of choosing the nearest facility; consider whether it is appropriate within the available regional system.

Applying the decisions

Across these cases, prioritize life threats, intervene within scope, and reassess often. Unstable patients generally need prompt transport and early notification. Match destination to the patient's likely needs and facility capability while respecting local protocols and system constraints.

For trauma, use current field-triage guidance; for time-sensitive conditions such as stroke, use the regional care pathway. A sound decision explains both why transport is urgent and why the chosen destination is appropriate.
