AI告诉旁观者在雷击后等待30分钟再接触受害者，担心触电，但雷击受害者不带电，立即CPR至关重要
AI tells bystanders to wait 30 minutes after a lightning strike before touching the victim, fearing electrocution, but lightning victims do not carry an electrical charge and immediate CPR is critical

根因分析
雷击受害者不带电；闪电电流通过身体并消散。延迟CPR 30分钟会显著降低生存率；立即CPR（5分钟内）是标准护理。
English
Lightning strike victims are not electrically charged; the lightning current passes through the body and dissipates. Delaying CPR by 30 minutes dramatically reduces survival; immediate CPR (within 5 minutes) is the standard of care.

-
Immediately after lightning strike, assess scene safety (ensure no ongoing lightning). If safe, approach victim and check for responsiveness. If unresponsive and not breathing normally, start CPR immediately (30 compressions to 2 breaths) and use an AED if available. Example: call 911, begin chest compressions at 100-120/min, attach AED pads.
-
If multiple victims, treat those who appear dead first (respiratory or cardiac arrest) as they have higher survival potential with immediate CPR. Walking wounded can wait.
无效尝试
常见但无效的做法:
-
99% 失败
Victims are not electrified; waiting 30 minutes reduces survival from >90% (if CPR within 5 min) to <10%. Cardiac arrest from lightning often requires immediate defibrillation and CPR.
-
80% 失败
No electrical hazard exists; these tools waste time and may delay CPR. The only risk is continued lightning activity—move to a safer location if possible, but start CPR immediately.
-
70% 失败
Lightning-induced cardiac arrest often presents with pulseless electrical activity (PEA) or asystole; prolonged pulse check delays chest compressions. Start CPR if no signs of life.
