根因分析
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。
English
The AI incorrectly applies standard CPR protocols (check pulse for 5-10 seconds) to lightning strike victims, but lightning can cause primary cardiac arrest with asystole or ventricular fibrillation; the National Lightning Safety Council and AHA recommend immediate chest compressions without pulse check because the heart may be in a shockable rhythm and every second counts.

-
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.
-
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
常见但无效的做法:
-
85% 失败
Pulse checks in cardiac arrest are unreliable even for trained responders; the AHA recommends starting CPR immediately if unresponsive and not breathing normally.
-
95% 失败
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.
-
75% 失败
AEDs analyze rhythm and deliver shocks, but CPR is needed to maintain blood flow until the AED is ready; delay in compressions worsens outcomes.
