# AI告诉用户脱掉低体温症患者的湿衣服并用毯子包裹，但如果患者严重低体温，激进复温可能导致心脏骤停

## 根因

AI遗漏了关键细节：对于严重低体温症（核心温度<28°C），快速复温或粗暴操作可能因心肌易激惹而诱发心室颤动；正确做法是温和被动体外复温，避免胸外按压直至患者复温至30°C以上。

## 解决方案

1. ```
   For severe hypothermia: gently remove wet clothing, place victim in insulated sleeping bag or blankets, cover head with hat, and apply chemical heat packs ONLY to armpits, groin, and chest (not extremities). Do not move or jostle victim. Monitor breathing and pulse for 1 minute before assuming cardiac arrest.
   ```
2. ```
   Use a forced-air rewarming system (e.g., Bair Hugger) if available, set to 43°C (109°F) air temperature, applied to torso only. Alternatively, use warm (40-42°C) IV fluids if trained provider present.
   ```

## 无效尝试

- **Remove wet clothing and place victim in warm bath or apply hot water bottles directly to skin** — Aggressive active rewarming (hot bath, direct heat) can cause peripheral vasodilation leading to rewarming shock and cardiac arrest in severe hypothermia. (92% 失败率)
- **Start chest compressions immediately even if patient has a pulse but is unconscious** — Mechanical stimulation of the heart in severe hypothermia can induce ventricular fibrillation; only start CPR if patient is pulseless and after 30-45 seconds of pulse check. (85% 失败率)
- **Give warm oral fluids or alcohol to help rewarm from inside** — Oral fluids are contraindicated in altered mental status due to aspiration risk; alcohol causes peripheral vasodilation worsening heat loss. (90% 失败率)
