The degree of damage to the human body of electric shock and contact with the voltage level, the type of current such as direct current and alternating current, current strength, frequency level, skin resistance of the electrocution site, the length of time of electrocution, the environment in the meteorological conditions, etc., closely related to, and can not be generalized. People touching the ultra-high voltage or lightning, if not timely disengaged from the electrocuted parts may be a few seconds may be life-threatening, immediately disengaged from the power supply and rescue.
Electrocution is very dangerous, and severe ventricular fibrillation may occur at the time of electrocution. Light cases of electrocution can lead to burns on the skin, and in serious cases, there will be damage to the soft tissues of the muscles and the nervous system, and even cause cardiac arrest leading to death.
When you find an electric shock, cut off the power and call 120 at the first time. if there is a cardiac arrest, you need to perform CPR immediately. Because respiratory arrest will lead to cerebral anoxia, and cerebral anoxia after 1 minute will cause irreversible damage, and finally lead to brain death. Electrocution needs to be actively diagnosed and treated.
