HYPOTHERMIA-REWARM-ERR-001 emergency life_safety ai_generated true

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

Root Cause

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).

中文

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）。

Workarounds

  1. 75% success For severe hypothermia (no shivering, unconscious): handle gently, do not remove clothing, apply passive insulation (space blanket, vapor barrier), transport to hospital; active rewarming only with warm IV fluids or forced air warming in medical setting

  2. 95% success For mild hypothermia (shivering present): remove wet clothing, wrap in dry blankets, give warm sweet drinks, and encourage gentle movement

中文步骤

  1. 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
  2. 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

Dead Ends

Common approaches that don't work:

  1. 85% fail

    Movement of victim can trigger cardiac arrest; blankets alone may not prevent afterdrop

  2. 90% fail

    Causes rapid peripheral vasodilation, sending cold blood to core and dropping core temp further
