How to get an electric shock after the first aid?

Electrical injury, commonly known as electric shock, is due to current through the human body caused by injury. Mostly due to power supply caused by direct contact with the human body, there were more than a few kilovolt high-voltage or lightning hit. Access to more than 1,000-volt high-voltage multi-breathing to stop, 200-volt low-voltage power following easily cause cardiac defibrillators and cardiac arrest, 220 ~ 1000 V to the voltage at the same time the heart and central respiratory paralysis.

Symptoms
Strong current through the body, in the blink of an eye, people will immediately be dead or in shock and collapsed, the body will burn local circumstances.
Partial performance of different degrees of burns, bleeding, black and so on. Burn area boundaries with the surrounding normal tissue clearly, there are more than two wound, an entrance, one or more exports. Weight and subcutaneous tissue from deep wounds, tendons, muscles, nerves, and even as deep as bone, was carbonized state. Or general dysfunction, such as shock, respiratory cardiac arrest.
Cause of death is due to currents caused by the brain (medulla oblongata of the respiratory center) a high degree of inhibition, inhibition of myocardial and ventricular fibrillation. After the injury and electric shock voltage, current, and the situation of the conductors of the contact surface. High voltage, current, and resistance of small, surface moist and easy to death: If the current from the side of limb or body to pay to import, or body-drying, resistance, and may cause burns and may not be dead.
First aid methods
1, immediately cut off the power supply, or non-conductive objects, such as dry wooden sticks, bamboo sticks or dry cloth and other objects so that the wounded from the power supply as soon as possible. First direct contact with an electric shock not to the wounded, to prevent electric shock and the impact of their conduct of the rescue work.
2, when the wounded from the power supply should immediately check the situation of the wounded body, especially the breathing and heartbeat and found that breathing, heart beat stopped immediately to save the spot.
(1) mild: that is, conscious, breathing heart rate were independent, and the wounded lying in situ, close observation, not to stand or walk, to prevent shock or heart failure secondary.
(2) respiratory arrest, cardiac arrest exists, the local solution of loose lying衣扣, open airway, mouth-to-mouth artificial respiration immediately and conditions of tracheal intubation, artificial respiration of oxygen pressure. Acupuncture can also be people, 10 Sun, Yongquan temple, etc., or respiratory stimulants (such as mountain vegetables stem base, caffeine, Coramine).
(3) cardiac arrest, breathing beings, should be immediately closed chest cardiac massage.
(4) heart were to stop breathing, and artificial respiration at the same time should be implemented in external cardiac massage, breathing and circulation in order to establish and restore the body's oxygen supply of organs. The best scene of the incident were two purposes to mouth resuscitation and external cardiac massage to the ratio of 1:5, that is, 1st artificial respiration, cardiac massage 5 times. The scene of the incident as only 1 person, with the ratio of 15:2 for external cardiac massage and artificial respiration, that is, the first external cardiac massage for 15 times, and then artificial respiration mouth 2, and so on must adhere to the rescue in the end .
(5) to deal with electrical injury, attention should be given any other injury. Such as electric shock from power after the bombs fall or high altitude, often complicated by craniocerebral injury, hemopneumothorax, visceral rupture, limb and pelvic fractures. If trauma, burns should be addressed simultaneously.
(6) in the scene of the incident, do not move the casualty, if needed to move, to save time should not be interrupted more than 30 seconds. Mobile injured or to hospital, with the exception of the wounded should be flat on the stretcher and the back pad to ping wide plank hard things, should continue to rescue, to stop breathing heartbeat should continue artificial respiration and external cardiac massage, in the hospital medical staff did not succeed before the treatment could not be suspended.
