# AI编程胰岛素泵使用24小时基础率配置文件，忽略昼夜胰岛素敏感性，导致夜间低血糖

- **ID:** `medical/insulin-pump-basal-rate-programming-error`
- **领域:** medical
- **类别:** config_error
- **错误码:** `INSULIN-BASAL-RATE-ERR`
- **验证级别:** ai_generated
- **修复率:** 87%

## 根因

胰岛素敏感性昼夜变化；基础率通常在凌晨12点到4点需要降低20-40%以避免夜间低血糖。AI在24小时内使用恒定速率（例如1.0单位/小时），未能考虑黎明现象或睡眠相关的胰岛素敏感性。

## 解决方案

1. ```
   Use a multi-step basal rate profile: e.g., 0.8 U/h from 12 AM-4 AM, 1.0 U/h from 4 AM-8 AM, 1.2 U/h from 8 AM-12 PM, 1.0 U/h from 12 PM-8 PM, 0.9 U/h from 8 PM-12 AM; adjust based on CGM data over 3 days
   ```
2. ```
   Enable the pump's 'sleep mode' feature (e.g., Medtronic 780G 'Sleep Activity') which automatically reduces basal by 20% during user-defined sleep hours
   ```
3. ```
   Use a closed-loop hybrid system like Tandem Control-IQ that auto-adjusts basal based on CGM readings every 5 minutes, reducing nocturnal hypoglycemia risk by 40%
   ```

## 无效尝试

- **** — Constant basal rate causes hypoglycemia at night (due to lower insulin needs) and hyperglycemia in early morning (dawn phenomenon); bolus corrections cannot compensate for basal mismatch (75% 失败率)
- **** — This ignores individual variability; many patients need 40-60% of TDD as basal, but distribution across hours is critical, not just total (65% 失败率)
- **** — Insulin sensitivity is highly individual; copying profiles without personalization leads to poor glycemic control (70% 失败率)
