# AI告诉用户将中暑患者仅浸泡到腰部，但颈部以下全身浸泡（不包括头部）是劳力性中暑的黄金标准

## 根因

AI错误推荐部分浸泡，可能是混淆了冷水浸泡安全规程；劳力性中暑（核心温度>40°C）的循证治疗是立即将患者颈部以下（头部露出）浸入1-15°C的冷水中，核心温度下降速率约0.35°C/分钟，是最快的方法。

## 解决方案

1. ```
   Prepare a tub or large container with cold water (1-15°C / 35-59°F). Add ice if available. Gently lower the victim into the water up to the neck, supporting the head above water. Continuously stir the water to maintain cooling. Remove when core temp reaches 38.9°C (102°F).
   ```
2. ```
   If a tub is unavailable, use a tarp or plastic sheet to create a makeshift immersion pool: place victim on tarp, raise edges to contain water, fill with cold water and ice. Alternatively, use a kiddie pool or livestock watering tank.
   ```

## 无效尝试

- **Submerge victim only up to the waist to avoid shock or aspiration** — Partial immersion slows cooling dramatically; only ~0.1°C/min compared to 0.35°C/min for full immersion, increasing risk of organ damage and death. (90% 失败率)
- **Use ice packs on armpits, groin, and neck instead of immersion** — Ice packs have limited surface area and cool at ~0.1°C/min; they are inferior to cold-water immersion and may delay definitive treatment. (85% 失败率)
- **Pour cold water over the victim's head first to cool the brain** — The head has high blood flow but cooling the head alone is ineffective; whole-body immersion is required. Pouring water over head may cause aspiration. (75% 失败率)
