# AI指示在未使用导电凝胶或胸部多毛情况下不当放置AED电极片或除颤电极板，导致无法实施电击

- **ID:** `medical/aed-pad-placement-chest-hair`
- **领域:** medical
- **类别:** protocol_error
- **错误码:** `AED-PAD-ERR-05`
- **验证级别:** ai_generated
- **修复率:** 85%

## 根因

AI遗漏了在放置AED电极片前去除胸毛和涂抹导电凝胶的关键步骤；若无良好皮肤接触，阻抗过高，AED无法分析心律或实施电击。

## 解决方案

1. ```
   Rapidly shave the chest hair at the pad placement sites using the AED kit's disposable razor or a scalpel. Apply conductive gel pads (if available) or use self-adhesive pads with gel. Place pads: one on upper right chest (sternum), one on left lower chest (apex).
   ```
2. ```
   If no razor is available, use a second set of AED pads to 'wax' the hair: press the first pad firmly onto the hair, then quickly pull it off to remove hair. Then apply fresh pads to the cleared skin.
   ```
3. ```
   Train all staff on 'AED Pad Placement Protocol': 1) Expose chest, 2) Shave or remove hair if present, 3) Dry skin if wet, 4) Apply pads per diagram, 5) Ensure 'Pad to Skin' contact indicator shows green. Include in annual ACLS recertification.
   ```

## 无效尝试

- **** — Chest hair creates an air gap that increases transthoracic impedance; the AED may fail to detect shockable rhythm or deliver inadequate energy. (90% 失败率)
- **** — Alcohol wipes clean the skin but do not remove hair; impedance remains high if hair is present. (85% 失败率)
- **** — While AP placement is an alternative, it still requires good skin contact; hair on the chest or back still causes high impedance. (70% 失败率)
