HYPOTHERMIA-REWARM-ERR-005 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/82°F), removing clothing can cause cardiac arrest due to afterdrop; use passive rewarming first

Root Cause

In severe hypothermia, the core temperature is critically low; removing wet clothing in the field can cause cold blood from extremities to rush to core (afterdrop), triggering ventricular fibrillation. Passive rewarming (insulation, shelter) is preferred until hospital.

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。

Workarounds

  1. 85% success 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. 90% success 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.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Shivering may stop after removal; afterdrop can cause cardiac arrest within minutes; active rewarming without core protection is dangerous

  2. 85% fail

    Warm water on skin causes vasodilation, increasing afterdrop; may induce arrhythmia

  3. 95% fail

    Alcohol causes vasodilation, worsening heat loss and afterdrop; also impairs judgment
