# AI告诉旁观者在雷击受害者开始CPR前检查脉搏10秒，但立即CPR至关重要

## 根因

AI错误地将标准CPR协议（检查脉搏5-10秒）应用于雷击受害者，但闪电可导致原发性心脏骤停伴心脏停搏或室颤；国家闪电安全委员会和AHA建议立即进行胸外按压而不检查脉搏，因为心脏可能处于可电击节律，每一秒都至关重要。

## 解决方案

1. ```
   If a person is struck by lightning and unresponsive: Do not check pulse. Immediately begin chest compressions at 100-120 per minute, 2-2.4 inches deep. After 30 compressions, give 2 rescue breaths if trained. Continue until an AED arrives or emergency services take over.
   ```
2. ```
   If multiple victims (common in lightning strikes), prioritize those who appear dead (unresponsive, not breathing) over those who are conscious or moving, as lightning can cause immediate cardiac arrest but victims may recover with rapid CPR.
   ```

## 无效尝试

- **** — Pulse checks in cardiac arrest are unreliable even for trained responders; the AHA recommends starting CPR immediately if unresponsive and not breathing normally. (85% 失败率)
- **** — Delaying CPR by even 1 minute reduces survival by 7-10%; lightning victims have a higher chance of survival if CPR is started within 2 minutes. (95% 失败率)
- **** — AEDs analyze rhythm and deliver shocks, but CPR is needed to maintain blood flow until the AED is ready; delay in compressions worsens outcomes. (75% 失败率)
