# AI告诉用户移除失温受害者的湿衣服并用毯子包裹，但如果受害者严重失温（<28°C/82°F），移除衣服可能因后降效应导致心脏骤停；应首先使用被动复温

## 根因

在严重失温时，核心温度极低；野外移除湿衣服可能导致四肢冷血涌回核心（后降效应），引发室颤。应首选被动复温（保温、庇护）直至送医。

## 解决方案

1. ```
   For severe hypothermia (unconscious, no shivering): do not remove clothing. Place victim in hypothermia wrap: multiple layers of blankets, sleeping bag, and vapor barrier (e.g., plastic sheet). Handle gently to avoid cardiac arrest. Example: use a 'burrito wrap' with wool blanket inside plastic tarp.
   ```
2. ```
   If victim is conscious and shivering (mild hypothermia), remove wet clothing in a sheltered area and replace with dry layers. Provide warm sweet drinks if alert.
   ```
3. ```
   Use chemical heat packs on armpits, groin, and neck (over clothing) to provide external heat without removing clothes
   ```

## 无效尝试

- **** — Shivering may stop after removal; afterdrop can cause cardiac arrest within minutes; active rewarming without core protection is dangerous (90% 失败率)
- **** — Warm water on skin causes vasodilation, increasing afterdrop; may induce arrhythmia (85% 失败率)
- **** — Alcohol causes vasodilation, worsening heat loss and afterdrop; also impairs judgment (95% 失败率)
