Electric Shock (other)
An electrical injury (electric injury) or electrical shock (electric shock) is damage sustained to the skin or internal organs on direct contact with an electric current. The injury depends on the density of the current, tissue resistance and duration of contact. Very small currents may be imperceptible or only produce a light tingling sensation. However, a shock caused by low and otherwise harmless current could startle an individual and cause injury due to jerking away or falling. A strong electric shock can often cause painful muscle spasms severe enough to dislocate joints or even to break bones. The loss of muscle control is the reason that a person may be unable to release themselves from the electrical source; if this happens at a height as on a power line they can be thrown off. Larger currents can result in tissue damage and may trigger ventricular fibrillation or cardiac arrest. If death results from an electric shock the cause of death is generally referred to as e ...

Lightning Injury
Lightning injuries occur when someone is Lightning strike, struck by lightning. Initial symptoms may include heart asystole and respiratory arrest. While the asystole may spontaneously resolve fairly rapidly, the respiratory arrest is typically more prolonged. Other symptoms may include burns and blunt injuries. Of those who survive, about 75% have ongoing health problems as a result, such as cataracts and hearing loss. If death occurs it is typically from either an arrhythmia, abnormal heart rhythm or respiratory failure. Lightning injuries are divided into direct strikes, side splash, contact injury, and ground current. Ground current occurs when the lightning strikes nearby and travels to the person through the ground. Side splash makes up about a third of cases and occurs when lightning strikes nearby and jumps through the air to the person. Contact injury occurs when the person is touching the object that is hit. Direct strikes make up about 5% of injuries. The mechanism o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
