Hypothermia Management - Simplified Algorithm
FIRST: Scene Safety
STEP 1: Assess the Patient
Normal mental status?
├── YES → NOT HYPOTHERMIC → No action needed
└── NO ↓
Shivering?
├── NO → Shivering but functioning?
│ ├── YES → MILD (35-32°C)
│ └── NO → MILD (35-32°C)
└── YES ↓
Still shivering?
├── YES → MODERATE (32-28°C)
└── NO ↓
Conscious?
├── YES → MODERATE (32-28°C)
└── NO ↓
Signs of life / rhythm on ECG?
├── YES → SEVERE/PROFOUND (<28°C)
└── NO ↓
Lethal injury? Chest too stiff? Avalanche >35 min + airway blocked?
├── YES → DEATH - Do not resuscitate
└── NO → SEVERE/PROFOUND (<28°C) + CPR
STEP 2: Treat by Category
🟡 NOT HYPOTHERMIC (>35°C / Cold Stressed)
- Reduce heat loss, increase heat production
🟠 MILD (35-32°C)
- Insulate + vapor barrier, seek shelter
- Remove wet clothing only with shelter
- Measure temperature
- Passive warming + calorie support for shivering
- No standing/walking for 30 min
- Active warming is beneficial
🔴 MODERATE (32-28°C)
- Apply heat to upper torso (chest, axilla, back) - heat pads, forced air
- IV/IO access; saline boluses (40-42°C)
- IV/IO glucose
- Monitor continuously
- No standing or walking
🆘 SEVERE/PROFOUND (<28°C)
- Intubate or use supraglottic airway
- Lower anesthetic/paralytic drug doses; extend dosing intervals
- Ventilate at half the normal rate (with advanced airway)
- Supplemental O₂ (especially >2500m)
- Naso/orogastric tube if intubated
- Compressions at normal rate
- If <30°C: 1 shock max (VT/VF); warm 1-2°C before more shocks
- No vasopressors until ≥30°C (increase interval 30-35°C)
- CPR may be paused/intermittent if needed for evacuation
- No temperature cut-off for CPR
- Stop CPR if potassium >12
- Consider transcutaneous pacing if bradycardic + hypotensive
STEP 3: Transport
| Condition | Destination |
|---|---|
| Uninjured, alert, shivering | May not need hospital |
| Trauma patient | Trauma center (active rewarming) |
| Asphyxiated | Closest hospital |
| Hemodynamically stable | Closest hospital |
| Unstable / Severe | Hospital with ICU + ECMO (ECC) capabilities |
