HYPOTHERMIA-REWARM-ERR-006 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 (<28°C), this can cause rewarming shock and cardiac arrest

Root Cause

The AI applies standard mild hypothermia treatment to severe hypothermia cases; for core temperature below 28°C, the heart is irritable and rough handling or rapid external rewarming can trigger ventricular fibrillation. The correct approach is gentle handling, passive external rewarming only (remove wet clothing slowly, insulate with dry blankets), and active internal rewarming (warm IV fluids, heated oxygen) by medical professionals.

AI将标准轻度低体温治疗应用于严重低体温病例；当核心温度低于28°C时，心脏易激惹，粗暴处理或快速外部复温可能引发心室颤动。正确方法是轻柔处理、仅进行被动外部复温（缓慢移除湿衣物，用干毯子保温），并由医疗专业人员实施主动内部复温（温热静脉输液、加热氧气）。

Workarounds

  1. 90% success For severe hypothermia (unconscious, no shivering): handle the victim extremely gently—do not rub limbs or move unnecessarily. Cut away wet clothing carefully while keeping victim horizontal. Insulate with dry blankets, sleeping bag, or emergency bivvy. Cover head and neck. Do not apply external heat sources. Transport to hospital immediately. Example command: 'Cut the wet clothing off while the person lies flat. Wrap them in a dry sleeping bag or blankets, head included. Do not massage arms or legs.'

  2. 85% success If active rewarming is available (hospital setting): administer warmed IV fluids (40-42°C), heated humidified oxygen (40-45°C), and consider warm peritoneal or pleural lavage for core temperature <28°C. Monitor cardiac rhythm continuously.

Dead Ends

Common approaches that don't work:

  1. 85% fail

    Vigorously removing wet clothing or moving the victim can cause afterdrop (core temperature continues to fall) and trigger ventricular fibrillation if core <28°C

  2. 75% fail

    Applying hot water bottles or heating pads directly to skin causes peripheral vasodilation and rewarming shock, dropping blood pressure and potentially causing arrest

  3. 60% fail

    Giving warm alcohol (e.g., whiskey) to a hypothermia victim worsens hypothermia by causing vasodilation and impairing shivering thermogenesis
