What Is The Specific Method Of First Aid On Site When An Electric Shock Occurs
1. Quickly release the power supply: In the event of an electric shock, you must not panic or be at a loss. First of all, you must immediately cut off the power supply to make the patient out of the state of current damage. This is the primary factor for the success of the rescue, because when an electric shock occurs, the current Those who will continue to pass the electric shock, from the factors that affect the stimulation of the electric current to the human body, we know that the longer the electric shock time, the more serious the damage to the human body. In order to protect the patient, only cut off the power immediately. Secondly, when a patient gets an electric shock, electricity flows through his body, which has become a charged body, which is a serious threat to the rescuer. If you do not pay attention to safety, the rescuer will also get an electric shock. Therefore, the patient must be disconnected from the power source before rescue. There are many ways to disconnect the patient from the power source:
A. When there is a power switch and a power plug near the accident, you can immediately turn on the knife and remove the plug to cut off the power. However, ordinary light switches (such as pull-wire switches) can only turn off one wire, and sometimes the phase wire may not necessarily be turned off, so it cannot be considered that the power is turned off.
B. When a live wire touches the human body and causes contact, and other methods can not be used to disconnect the power supply, the wires can be removed with insulating objects (such as wooden sticks, bamboo poles, gloves, etc.) to remove the patient from the power supply.
C. If necessary, use insulated tools (such as electrician's pliers with insulated handles, axe with wooden handle, hoes, etc.) to cut off the power supply. In short, there are two issues that need to be paid attention to when the site can be adapted to local conditions and various methods can be used flexibly to quickly cut off the power supply and release the power supply:
A. After being disconnected from the power source, the muscles of the human body are no longer stimulated by the electric current and will relax immediately. The patient can fall on their own, causing new trauma (such as skull base fracture), especially at high altitudes. Therefore, corresponding measures must be taken to prevent this kind of situation from aggravating the condition if it is disconnected from the power supply.
B. Pay attention to safety when disconnecting the power supply, and never injure others by mistake, which will amplify the accident.
2. Simple diagnosis: After the power is released, the patient is often in a coma and the condition is unknown. Therefore, it is necessary to make a judgment on the heartbeat and breathing as soon as possible to see if they are in a "pseudo-death" state, because only a clear diagnosis can be timely and correct Get first aid. Patients who are in a "pseudo-death" state are in a very dangerous state due to severe hypoxia in all tissues of the body, so a complete set of routine methods cannot be used for systematic examination. You can only use some simple and effective methods to judge and see if there are types of "fake death" and "fake death", which achieves the purpose of simple diagnosis. The specific method is as follows: quickly move the patient after being disconnected from the power supply to a relatively ventilated and dry place, make him lie on his back, and relax his shirt and trousers.
A. Observe whether there is breathing. When there is breathing, we can see that the muscles of the chest gallery and abdomen move up and down with breathing. Put your hand on the nostril, you can feel the flow of gas when you breathe. On the contrary, without the above phenomenon, it is often that breathing has stopped.
B. Touch the artery in the neck and the femoral artery in the groin to see if there is a pulsation, because when there is a heartbeat, there must be a pulse. The carotid and femoral arteries are both large arteries with superficial locations, so it is easy to feel their pulsation, so they are often used as the basis for whether there is a heartbeat. In addition, in the precordial area, you can also hear whether there is a heartbeat, and if there is a heartbeat, there is a heartbeat.
C. Check to see if the pupils are dilated. The role of the pupil is a bit like the aperture of a camera, but the human pupil is an aperture that is automatically adjusted by the brain. When the brain cells are normal, the size of the pupil will adjust itself according to the changes in the external light, so that the intensity of the light entering the eye Moderate, easy to watch. When in the state of "pseudo-death", the brain cells are severely hypoxic and on the verge of death, so the center of the entire automatic adjustment system loses its function, and the pupils expand on their own, and can no longer regulate the intensity of light, so The dilated pupils indicate that the brain tissue cells are severely hypoxic, and the human body is in a state of "pseudo-death". Through the above simple inspection, we can determine whether the patient is in a "feign death" state. And according to the classification standard of "fake death", it can be known that it belongs to the type of "fake death". In this way, we can be targeted and treat the symptoms appropriately during the rescue.
3. Treatment method: patients after a simple diagnosis can generally be treated according to the following conditions:
A. The patient is conscious, but feels fatigue, dizziness, palpitations, cold sweats, and even nausea or vomiting. Such patients should rest quietly on the spot, reduce the burden on the heart, and speed up recovery; when the condition is serious, be sent to the medical department carefully, and the medical staff should be checked and treated.
B. The patient's breathing and heartbeat are still present, but he is in a coma. At this time, the patient should be placed on his back, the surrounding air should be circulated, and attention should be paid to keep warm. In addition to close observation, preparations for artificial respiration and heart compression should be made, and the medical department should be notified immediately or the patient should be taken to the hospital on a stretcher. On the way to the hospital, pay attention to observe whether the patient has a sudden "false death" phenomenon. If there is false death, it should be rescued immediately.
C. If the patient is in a state of suspended animation after examination, the different types of "suspended death" should be treated immediately. If the heartbeat is stopped, the extracorporeal artificial heart squeeze method is used to maintain blood circulation; if the breathing is stopped, the mouth-to-mouth artificial respiration method is used to maintain gas exchange. When breathing and heartbeat stop, you need to perform extracorporeal heart squeezing method and mouth-to-mouth artificial respiration method at the same time, and call the hospital for help at the same time. In the rescue process, the rescue work cannot be stopped at any time. Even on the way to the hospital, the rescue must be continued, and the rescue must be carried out while the heartbeat and breathing are restored.
4. Mouth-to-mouth artificial respiration: The purpose of artificial respiration is to replace the breathing activity of the lungs with artificial methods, so that gas enters and exits the lungs rhythmically, provides enough oxygen in the body, fully discharges carbon dioxide, and maintains normal ventilation Features. There are many methods of artificial respiration, and mouth-to-mouth artificial respiration is currently considered to be the best. The operation method of mouth-to-mouth artificial respiration is as follows:
A. Lie the patient on his back, untie the collar, loosen the tights, and loosen the trousers, so as not to affect the natural expansion of the chest during breathing. Then turn the patient's head to one side, open his mouth, and use his fingers to remove dentures, blood clots, and vomit in the mouth to make the airway unblocked. Three-phase AC power supply price
B. The rescuer is on the patient’s side, pinches the patient’s nose with one hand close to his head (to avoid air leakage), presses the outer edge of the palm of his hand against his forehead, and puts the other hand on the back of the patient’s neck. Lift the head up, so that the head is fully tilted back to relieve the airway obstruction caused by the drop of the tongue. Three-phase AC voltage stabilizer price
C. First-aiders take a deep breath, and then use their mouth close to the patient's mouth or nostrils to blow in, while observing whether the chest is raised, to determine whether the blow is effective and appropriate. Three-phase isolation transformer price
D. After the insufflation stops, the first aider turns his head slightly, and immediately relaxes the hands that pinch the nostrils to let the gas escape from the patient's lungs. At this time, pay attention to the recovery of the chest, listen to the sound of exhalation, and observe whether there is a respiratory tract obstruction.
E. Repeat this, blowing 12 times per minute, that is, blowing once every 5 seconds.
