Observe online news: in life, accidents are often sudden, and when medical professionals are unable to reach the scene in a timely manner, the ability of people close to the patient to provide first aid largely determines the length of life. Learning about first aid is key not only to the security of one's own life, but also to being the guardian of others ' lives。
A 1 minute delay in survival, 10%
According to the data, the number of heart-borne deaths in the country is 550,000 per year, and the number of patients in the brain is over 13 million. With a 10-per-cent reduction in the survival rate for every minute of rescue delay, timely and effective relief is essential。
Dr. Guo wei, deputy director of emergency internal services, beijing people's hospital: why are we calling gold rescue for four minutes, because if it was more than four minutes, some irreversible damage to the brain began to occur. The success rate of treatment will be significantly reduced。
At present, the average time of arrival of emergency vehicles in beijing is about 10 minutes. Although in the future the first aid vehicle will reach the scene as soon as possible, it will be difficult to reach within four minutes, even if sooner。
Gw: if this patient vomits, you have to get the patient sideways, and then avoid vomiting, and cause inhalation pneumonia to block the gas。
Don't be blind. Keep the patient resting
While waiting for help, the exact time at which the patient begins to experience symptoms is accurately recorded, while at the same time not being free to feed drugs or water. Do not depress the pressure blindly, let alone drag the patient, avoid violent shaking or attempt to “sure” the patient by shouting, which may aggravate the condition and allow the patient to remain absolutely resting。
The head of the beijing emergency centre training centre chen ji: that means he can't move, even move. Because at this point, the heart is very fragile, and even if we take him a few steps, this physical activity could be the last straw to crush a heart attack。
Blocked the airway
There is also a need for “gold four minutes” and for first aid when suffocated. In recent days, chongqing citizens' combined first aid video of girls who had been blocked by pearl milk tea has been circulated online. In the video, we can see that after the sudden fall of the girl, several zhongqing citizens carried out a series of heimlik first aid to the girl, which eventually succeeded in causing the girl to cough out the stuffed airway。
Liu shaozawa: asphyxiation is the cause of respiratory blockage, which causes oxygen deficiency in the human body, short-term respiratory respiratory failure, damage to the nervous system and other organs, and even endangers life。
Doctors have suggested that when people are found to be blocked, a number of people beat them hard on their backs, but this may result in food being more embedded and air-traffic congestion. How to do the right heimrick first aid was demonstrated by doctors。
Liu shaozawa: we quickly go around the back of the patient, with our feet between the patient's feet, spread them a little bit, and present a bow (step). The left hand puts two fingers on the patient's belly umbilical cord, the right hand on the upper two fingers of the umbilical cord, and then the left hand wraps the fist around the upper abdomen of the patient, with a quick impact in the direction of the inside and up. This is repeated shocks until the patient can cough or cough the alien out, and at the same time we can see if the patient is in a red state。
The doctor advised that if the patient is taller, it is necessary to bend the back down as far as possible, while the rescuer stomps slightly, using the same method, and strikes quickly on the abdomen. If the pregnant woman is asphyxiated, the position of the arms around her must be further horizontally paralleled to avoid damage to the foetus。
First aid in the event of an unexpected emergency is essential. However, the so-called “first-aid approach”, which is well known to many, is in fact a dangerous error zone and may aggravate harm. I'm going to take a couple of hf first aid bugs for you today and help you avoid the risk of doing bad things。
Don't put anything in your mouth
Put something in your mouth when you have an epilepsy. Many believe that this would prevent the patient from biting his tongue, but in practice, forced plugs may lead to broken teeth, damage to his teeth, and even to asphyxiation caused by alien blockages. The correct approach is to allow the patient to lay down, untie the collar, clean up the rest of his mouth and avoid his injuries。
Chen zhi, director of the beijing emergency centre training centre: at the same time, keep an eye on him, while he convulsions, and don't try to restrain his limbs, otherwise it will cause a fracture。
Myocardial infarction
An approach such as “cough coughing during heart infarction promotes blood circulation and relieves heart infarction”, as described by experts, is strongly undesirable。
Guo wei: my heart infarction, most important of all, the veins are blocked. The severe cough doesn't help with the blood vessels, but it increases our oxygen consumption。
When heart infarction occurs, the patient is suffering from myocardial hemorrhage, and coughing hard increases the burden of the heart, which may cause heart disorder or even a heart break. The correct approach is to allow patients to lay down immediately, to remain quiet and to dial 120 quickly. If the patient is unconscious, immediate cpr is required。
I'm in a coma
It is also wrong that there is also the practice of “strangulation in a coma”. Not only is it impossible to awaken the unconscious, but it may also cause facial damage through excessive force. The correct approach is to first judge the patient's breathing, heart rate and immediately resuscitate the heart and lungs as soon as the heart rate stops。
Fish stings and throats
As the fishing season approaches, the risk of fish being caught increases. In the event that a fish is stabbing the throat, it is important not to try to swallow rice, be jealous and shaving with chopsticks in the wrong way of self-help, and in serious cases there are complications such as oesophagus。
Chen liang, deputy director of emergency care at the medical college, shanghai university of transportation: there's no way we can eat, even if we swallow. It's possible that any swallowing move could get the fish into the deep, which would increase the risk
The correct method is to cough and try to excrete fish thorns, so as not to cough so hard as to push them deeper. It would be better to go to the hospital and have the doctor remove it with professional equipment。
Hemorrhaging from external wounds
In everyday life, it is common to be cut with a sharp object such as glass, knives, etc. If flour, ash, earth, etc. Are scattered blindly, they may cause injury to sepsis, serious or may cause whole-body infections. If the wounds are shallow and hemorrhaging is low, the principles of “breeding, cleaning, dressing” are followed. If serious external bleeding is significant and accompanied by skin tissue on hand or neurological, muscular, etc., medical attention should be provided in a timely manner。
Burns, no toothpaste, sauce, etc
The risk of infection may be increased by burns, such as self-inflicted toothpaste, soy sauce, purple water, etc。
The first principle of treatment for burns is to use cold water for about 20 minutes to reduce local temperatures and remove clothes from the surface of the burns。
Serious burns should be treated in hospitals as soon as possible and professionally。
