Quick Answer
A lightning strike can cause severe burns, cardiac arrest, and neurological damage, often leading to long-term or fatal consequences for the victim.
Effects on the Body
A lightning strike can cause severe burns, both external and internal, due to the extremely high temperatures generated by the discharge. The temperature of a lightning strike can reach up to 50,000°C, hotter than the surface of the sun. This can cause third-degree burns, which destroy all layers of the skin and underlying tissues. In addition to burns, a lightning strike can also cause cardiac arrest, with the electrical discharge disrupting the heart’s rhythm. This is a major cause of death from lightning strikes.
Neurological Assessment and First Aid
When assessing a victim of a lightning strike, it’s essential to look for signs of neurological damage, such as loss of consciousness, seizures, and confusion. If the victim is unresponsive, start CPR immediately, beginning with 30 chest compressions followed by two breaths. Continue CPR until medical help arrives. If the victim is responsive, but has difficulty speaking or moving, provide support and keep them calm until medical help arrives. It’s also essential to treat any burns promptly, using cool water to reduce the temperature of the skin and minimize damage.
Prevention and Safety
Preventing a lightning strike is always the best course of action. If you’re caught in a thunderstorm, seek shelter immediately in a sturdy building or a hard-topped vehicle. Avoid open areas, such as fields or beaches, and stay away from tall objects, such as trees or power lines. If you’re in the wilderness, find a low-lying area, such as a valley or a depression, and crouch down with your feet together. This can help reduce your risk of being struck.
