电源通过身体而造成损伤,称为电击伤,俗称触电。损伤的程度常和电流的性质、强度、电压、触电时间的长短和身体接触部位的电阻等有关。一般来说,交流电比直流电的危害性大,造成的损伤亦较严重;不同的电压,其致死原因亦不同。电压在220伏以下的叫低电压,触电后先发生心室颤动或心搏停止;电压在1,000伏以上的叫高电压,触电后很快引起呼吸中枢麻痹而先呼吸停止;电压在220～1,000伏之间,往往心搏和呼吸停止同时发生。
Power damage through the body, known as electric shock, commonly known as electric shock. The degree of damage and the current nature of the current strength, voltage, the length of the contact with the body contact resistance and so on. In general, the AC is more harmful than DC, resulting in more serious damage; different voltage, the causes of death are also different. The voltage is called low voltage below 220 volts, the first occurrence of ventricular fibrillation or cardiac arrest after an electric shock; voltage above 1,000 volts called high voltage, the respiratory center paralysis caused by electrocution and respiratory arrest; voltage at 220 ~ 1,000 volts Between the heartbeat and respiratory arrest often occur at the same time.
