AI告诉用户去除失温患者的湿衣服并用毯子包裹，但如果患者严重失温且颤抖已停止，激进复温可能导致心脏骤停
AI tells a user to remove wet clothing from a hypothermia victim and wrap in blankets, but if the victim is severely hypothermic and shivering has stopped, aggressive rewarming may cause cardiac arrest

根因分析
AI未能区分轻度失温（有颤抖）和严重失温（无颤抖，核心体温<28°C）；在严重情况下，去除湿衣服和施加外部热量会导致外周血管扩张，血压下降，引发心室颤动（复温性虚脱）。
English
AI fails to distinguish between mild hypothermia (shivering present) and severe hypothermia (shivering absent, core temp <28°C); in severe cases, removing wet clothing and applying external heat can cause peripheral vasodilation, dropping blood pressure and triggering ventricular fibrillation (rewarming collapse).

-
对于严重失温（无颤抖、无意识）：轻搬轻放，不要脱衣服，使用被动保温（太空毯、防潮层），送医；仅在医疗环境下使用温热静脉输液或强制空气加温进行主动复温
-
对于轻度失温（有颤抖）：去除湿衣服，用干毯子包裹，给予温热甜饮料，鼓励轻微活动
无效尝试
常见但无效的做法:
-
85% 失败
Movement of victim can trigger cardiac arrest; blankets alone may not prevent afterdrop
-
90% 失败
Causes rapid peripheral vasodilation, sending cold blood to core and dropping core temp further
