HYPOTHERMIA-AFTERDROP-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 (<28°C) this can cause cardiac arrest from afterdrop

Root Cause

The AI fails to differentiate between mild and severe hypothermia; in severe cases (<28°C core temp), moving the victim or removing clothing can trigger ventricular fibrillation due to afterdrop (cold blood from periphery moving to core). The correct protocol is gentle handling, minimal movement, and passive rewarming with dry insulation.

AI未能区分轻度与重度失温；在重度失温（核心温度<28°C）时，移动患者或移除衣物可能因后降效应（外周冷血回流核心）引发心室颤动。正确做法是轻柔处理、最小移动，并用干燥绝缘物进行被动复温。

Workarounds

  1. 80% success For severe hypothermia: do not remove wet clothing; instead, wrap the victim in a vapor barrier (e.g., plastic sheet) and then in dry blankets or sleeping bags. Keep the victim horizontal and avoid any jarring movements. If conscious, give warm (not hot) sweet drinks.

  2. 75% success Use a portable hypothermia wrap kit: place chemical heat packs (e.g., HotHands) wrapped in cloth on the neck, armpits, and groin (but not directly on skin). Monitor for cardiac arrhythmias and be ready for CPR.

Dead Ends

Common approaches that don't work:

  1. 90% fail

    Rubbing or massaging limbs to warm the victim, but this forces cold blood back to the core and increases afterdrop risk.

  2. 85% fail

    Placing victim in hot water or using hot packs directly on skin, which can cause burns and rapid core temperature fluctuations.
