Electrocution is a kind of accident that often occurs in life, which refers to the harm caused by a certain amount of electric current passing through the human body. The degree of current damage to the human body depends on the size of the current. Generally speaking, even a small amount of electric current through the human body, there will be dizziness, palpitations, pale, or cause different degrees of skin burns. The following is the site first aid knowledge related to electrocution that I have organized for you, for your reference.
First aid knowledge of the scene of electrocution1. Immediately unplugged
Once the electrocution accident, can not be panic, helpless, first of all, we must try to make the electrocuted person out of the power supply. The way to get rid of the power supply is as follows:
(1) cut off the power supply. When the power switch or power plug near the scene of the accident, the air switch can be immediately disconnected or unplugged from the power supply, so that the electrocuted from the power supply. It must be pointed out that ordinary light switch (such as pull-wire switch) only cut off a wire, and sometimes disconnect the phase line is not necessarily, therefore, turn off the light switch does not necessarily cut off the power supply, need to take a reliable method to cut off the power supply.
(2) remove the charged wire with insulation. When the charged wire touching the human body caused electrocution, and can not use other methods to release the power, can be used to insulate the object (such as sticks, bamboo poles, etc.) will be removed from the wire, so that the patient from the power supply.
(3) cut off the live wire with insulated tools. Electrocution accidents, when necessary, can be insulated ]_ tool (such as with insulated handle of the electrician's pliers, wooden handle axe and hoe, etc.) to cut off the wire to disconnect the power supply.
(4) tugging the electrocuted person's clothes to get rid of the power supply. If the scene does not have the above three conditions, and the electrocuted person clothes dry, the rescuer can be wrapped with a dry towel, dry clothes equal to the dry hand to pull the electrocuted person's clothes to make it out of the power supply.
It must be pointed out that the above method is only applicable to 220/380V low voltage? Rescue of electrocution. For high-voltage electrocution should notify the power supply department in a timely manner, the use of appropriate emergency measures, so as to avoid the production of new accidents.
(5) release the power supply considerations are as follows:
① If electrocuted on the overhead line or working at height, once the power supply is disconnected, the electrocuted person from the power supply will suddenly relax the muscles, may cause a fall resulting in serious trauma. Therefore, it must be supplemented with appropriate measures to prevent secondary accidents and more serious consequences.
② release the power to move quickly, taking a lot of time will affect the whole rescue work.
③ In addition to pay attention to their own safety when off the power supply, but also need to prevent accidental injury to others, expanding the accident.
2. Rapid and simple diagnosis
After the electrocution of the person freed from the power supply, a simple diagnosis should be made quickly. If the electrocution is not serious, conscious, but panic, numbness of the limbs, general weakness and other symptoms, or electrocution patient had a coma, but has come to, the patient should be in the air circulation quiet rest, do not walk, pay attention to observation and ask the doctor to come to the treatment or sent to the hospital; if the patient has been comatose, the contents of the simple diagnosis include: judgment electrocution of the loss of consciousness, open the airway, to determine whether the breathing and heartbeat exist. and heartbeat exist.
(1) Determine whether the electrocution of the blurred consciousness, loss of consciousness. Rescuers can gently shake the electrocuted person or pat the electrocuted person's shoulder, and loudly call his name, or loudly ask? What's wrong with you? But the amplitude of the shake can not be too large, to avoid causing trauma. If there is no reaction, the strong stimulation method can be used to observe. The whole judgment time should be controlled within 5-10s, so as not to delay the rescue time. Once it is determined that the electrocuted person loses consciousness, that is to say, the situation is serious, and most of the cases are heartbeat and respiration have stopped. In order to sustained, correct and effective CPR, it is necessary to immediately call for help and greet the surrounding people to come to assist in resuscitation. At the same time should be to the local emergency medical department for help (such as dialing?120?emergency telephone).
(2) maintain the resuscitation position. Cardiopulmonary resuscitation for electrocution, electrocution must be in the supine position, that is, the head, neck, torso straight without twisting, hands on both sides of the torso, supine on the hard ground E. Accidents, regardless of the electrocution is in what position, must be converted to the above standard position (this position is also known as the? resuscitation position?) The person must be moved to the standard position described above (this position is also known as the resuscitation position?). If you need to change the position, when turning the electrocuted person must be smooth, so that all parts of the body into a whole rotation (head, neck, torso, hips at the same time), especially to protect the neck, you can hold the neck with one hand, and the other hand holding the shoulders, so that the electrocuted person smoothly turned to the supine position. After the electrocuted person is in the resuscitation position, the tight upper garment and pants belt should be relaxed immediately. If the electrocuted person is found to have heartbeat and respiration in the process of judging consciousness, but in a comatose state, at this time, his airway is very easy to be blocked by inhaled mucus, vomitus and tongue root, so it is necessary to immediately put him or her in the side-lying position? Therefore, it is necessary to immediately place the patient in the side-lying position of coma. This position avoids the risk of airway obstruction and facilitates the flow of mucus and other secretions from the oral cavity, which is also known as the "recovery position". This position is also known as the recovery position.
(3) Open the airway. After electrocution, the heart often stops beating, the electrocution of the loss of consciousness, jaw, neck and tongue muscle relaxation, resulting in the root of the tongue and epiglottis collapsed to the posterior wall of the pharynx and blocked the airway. When inspiratory, the airway is negative pressure, tongue and epiglottis play the role of one-way valve, aggravating airway obstruction leading to hypoxia. Therefore, the airway must be opened immediately to maintain normal ventilation. Tongue muscle attached to the mandible, can make the muscle tension action such as head tilt back, the mandible forward E raised, the root of the tongue can leave the posterior pharyngeal wall, the airway will be open. If there is no muscle tension, head tilt will not open the airway, and the mandible needs to be raised at the same time to open the airway. After the heart stops beating for 15s, the muscle tension will disappear, and then the head needs to be tilted back and the mandible needs to be lifted up to open the airway at the same time.
(4) Determine whether breathing exists. Under the condition that the airway is open, the rescuer's face is sideways to the electrocuted person's chest, and the ear is close to the electrocuted person's mouth and nostrils. Through? See, hear, feel? to determine whether breathing exists. That is, the ear to listen to the electrocuted person breathing whether there is the sound of gas flow, face feel whether there is the gas flow of the blowing sensation, to see whether the electrocuted person's chest or abdomen is synchronized with the respiratory? Breathing movement? The whole examination time shall not be more than 5 s. If the electrocuted person is found to have spontaneous respiration after the airway is opened, the airway shall be kept open and unobstructed. If it is judged that there is no breathing, then artificial respiration should be carried out immediately. Rescuers can be placed on the forehead hand of the thumb and forefinger gently pinch the nostrils of the electrocuted person, take a deep breath, with lips wrapped around the mouth of the electrocuted person to form a sealed airway. Then the gas will be blown into the mouth of the electrocuted person, through the airway into the lungs. When this is done it is clearly observed that ? Breathing action? Then the second blowing can be carried out. The time of the second blowing should be controlled within 2-3s to complete.
If the chest is not lifted with the blow, and the electrocuted person's chest is not heard or felt to be passively exhausting, the airway opening action must be repeated immediately. If necessary, the ? two-handed jaw lift method? If it does not work, it can be determined that the electrocuted person airway foreign body obstruction caused by the need to immediately try to lift. It should be noted that the electrocuted person because the airway is not open, can not be ventilated, and then the cardiac compression will be completely ineffective.
(5) determine whether there is a heartbeat. The heart plays the role of a blood pump in the human body, making blood circulate endlessly in the blood vessels, and making the arterial vasculature strictly beating. Therefore, as long as the arteries are pulsating, you can tell if there is a heartbeat. The carotid artery is the central artery, in the peripheral arterial pulsation is not obvious, can still touch the carotid artery pulsation, coupled with its location shallow easy to touch, so often as the basis for the presence of heartbeat.
