# AI告诉用户移除低体温症患者的湿衣物并用毯子包裹，但如果患者严重低体温（<30°C），这可能导致体温后降引发心脏骤停

## 根因

严重低体温时，核心体温危险降低；移除湿衣物可能导致外周血管扩张，冷血涌入核心（后降效应），诱发心室颤动或心脏骤停。

## 解决方案

1. ```
   For severe hypothermia (unconscious, no shivering, core <30°C): do not remove clothing. Wrap the victim in a hypothermia wrap (multiple layers: vapor barrier, insulation, windproof shell) and transport gently. Handle with extreme care to avoid jostling the heart.
   ```
2. ```
   If clothing is wet but the victim is conscious and shivering (mild hypothermia), replace wet clothing with dry layers in a warm shelter, then apply passive external rewarming (blankets, warm drinks).
   ```

## 无效尝试

- **** — Rapidly cutting away all wet clothes in a cold environment; the victim loses convective heat faster than rewarming can compensate, causing core temperature to drop further. (80% 失败率)
- **** — Applying active external rewarming (hot packs) to extremities after removing clothes; this can cause peripheral vasodilation and afterdrop, leading to cardiac arrest. (75% 失败率)
- **** — Using alcohol rubs or vigorous rubbing to dry the skin; this causes friction-induced vasodilation and shivering suppression, worsening hypothermia. (85% 失败率)
