Neftaly Practices for Efficient Assessment of Hypothermia in Mass Casualty Events
Hypothermia, defined as a core body temperature below 35°C (95°F), is a critical condition that can rapidly become life-threatening if not identified and managed promptly. In mass casualty events, such as natural disasters, accidents in cold environments, or maritime emergencies, multiple victims may simultaneously present with hypothermia, complicating assessment and triage. Neftaly Practices for Efficient Assessment of Hypothermia in Mass Casualty Events equips first responders, emergency medical teams, and healthcare providers with structured, evidence-based strategies to rapidly identify, prioritize, and manage patients at risk of hypothermia in challenging, high-pressure scenarios.
Core Principles of Neftaly Hypothermia Assessment
- Safety and Environmental Assessment
Ensure responders are safe from environmental hazards, including snow, ice, water, wind, or unstable terrain.
Use personal protective equipment (PPE) to prevent secondary casualties and maintain responder safety.
Quickly identify environmental contributors to hypothermia, such as prolonged exposure to cold, wet clothing, or immersion in water.
- Rapid Recognition of High-Risk Patients
Key indicators of severe hypothermia include:
Shivering (early sign; may be absent in severe cases)
Pale, cold, or cyanotic skin
Altered mental status: confusion, lethargy, or unconsciousness
Weak or irregular pulse and bradycardia
Slow or shallow breathing
Loss of coordination or inability to walk
Infants, elderly, and victims with comorbidities are particularly vulnerable and may deteriorate rapidly.
- Systematic Primary Assessment
Apply the ABCDE framework (Airway, Breathing, Circulation, Disability, Exposure) while considering hypothermia-specific signs.
Assess core body temperature using reliable thermometers if available, especially in moderate-to-severe cases.
Identify coexisting conditions such as trauma, shock, or drowning, which may exacerbate hypothermia.
- Structured Triage and Prioritization
Prioritize patients according to hypothermia severity and risk of deterioration:
Red (Immediate): Severe hypothermia (<32°C) with impaired consciousness, hypotension, or respiratory compromise
Yellow (Delayed): Moderate hypothermia (32–35°C) who are alert but at risk of rapid deterioration
Green (Minor): Mild hypothermia (>35°C) with preserved cognitive and motor function
Black (Expectant/Deceased): Non-survivable injuries or persistent cardiac arrest
Neftaly Practices in Action
- Initial Scene Assessment
Identify cold exposure sources, water immersion, and environmental hazards.
Establish warming zones and triage areas to separate high-risk patients.
- Primary Survey – ABCDE Evaluation
Airway: Ensure patency; hypothermia can depress airway reflexes.
Breathing: Monitor respiratory rate and provide supplemental oxygen if hypoxic.
Circulation: Assess pulse, blood pressure, and perfusion; be aware of arrhythmias in severe hypothermia.
Disability: Evaluate mental status using AVPU or Glasgow Coma Scale.
Exposure: Remove wet clothing and protect from further heat loss using blankets, insulated clothing, or hypothermia wraps.
- Rapid Interventions
Active rewarming: Use warm blankets, radiant heaters, or warmed IV fluids for moderate-to-severe cases.
Passive rewarming: Move mild cases to sheltered, warm environments.
Monitor vital signs continuously and watch for cardiac arrhythmias.
Transport critically hypothermic patients promptly to facilities capable of advanced rewarming and intensive care.

Benefits of Neftaly Hypothermia Assessment Practices
Early Recognition: Detects hypothermia before life-threatening deterioration.
Structured Response: Reduces errors in chaotic mass casualty events.
Optimized Resource Allocation: Prioritizes patients most at risk for immediate intervention.
Improved Outcomes: Enhances survival rates and prevents hypothermia-related organ failure.
Neftaly Practices for Efficient Assessment of Hypothermia in Mass Casualty Events provides systematic, rapid, and effective strategies to assess, triage, and stabilize victims, ensuring timely interventions and improving survival in cold-exposure emergencies.
