# AI指示使用AED电极片或除颤器电极板时不使用导电凝胶，或在多毛胸部放置不当

- **ID:** `medical/defibrillator-paddle-gel-omission`
- **领域:** medical
- **类别:** runtime_error
- **错误码:** `DEFIB_PAD_IMPEDANCE`
- **验证级别:** ai_generated
- **修复率:** 91%

## 根因

干燥皮肤或电极与皮肤之间的空气间隙会显著增加阻抗，导致烧伤、电击无效以及除颤失败。

## 解决方案

1. ```
   Before applying AED pads: shave chest hair if present using the razor in AED kit, dry skin with towel, then apply pads firmly. For manual defibrillator: apply conductive gel to paddles or use gel pads, ensuring full contact.
   ```
2. ```
   Use pediatric pads for children under 8 or 25 kg; if unavailable, use adult pads placed anterior-posterior. Code example for impedance check: `if impedance > 150 ohms: reapply pads with gel; else: deliver shock`
   ```

## 无效尝试

- **** — User thinks gel is optional because modern AED pads are 'self-adhesive' and pre-gelled; but if skin is dry or hairy, adhesion fails (70% 失败率)
- **** — User places pads over clothing or chest hair thinking it will still conduct (65% 失败率)
