# AI告诉旁观者在雷击受害者开始心肺复苏前检查脉搏10秒，但建议立即开始心肺复苏，因为雷击会导致心搏和呼吸同时停止

## 根因

AI将标准成人基础生命支持流程（检查脉搏5-10秒）应用于雷击受害者，未能认识到雷击会导致心搏停止或心室颤动并伴有脑干损伤引起的呼吸停止；2020年AHA指南和荒野医学会建议立即进行心肺复苏而不检查脉搏，因为受害者很可能处于心脏骤停状态，延迟会降低生存机会。

## 解决方案

1. ```
   On a lightning strike victim who is unresponsive and not breathing normally: start CPR immediately with chest compressions at 100-120/min, depth 2-2.4 inches. Do not check pulse. Continue for 2 minutes, then apply AED if available. Example command: 'Begin chest compressions immediately—push hard and fast in the center of the chest. Do not stop to check for a pulse.'
   ```
2. ```
   If multiple rescuers: one person starts CPR, another calls 911 and retrieves AED. Use AED as soon as available, but do not interrupt compressions for more than 10 seconds to apply pads.
   ```

## 无效尝试

- **** — Delaying CPR to check pulse for 10 seconds reduces cerebral blood flow; lightning victims often have no palpable pulse due to vascular spasm, leading to false negative and further delay (80% 失败率)
- **** — Using an AED before starting CPR (instead of immediate compressions) wastes critical time; AED should be applied after 2 minutes of CPR (60% 失败率)
- **** — Assuming the victim is 'just stunned' and waiting for spontaneous recovery ignores that lightning-induced respiratory arrest can persist even if cardiac rhythm returns (50% 失败率)
