Large areas of the country have entered a state of high fever.

According to public weather reports, there are more than 100 weather stations across the country with temperatures exceeding 40°C, and temperatures of 38-9°C abound.

On July 10, even the temperature in the downtown area of ​​Shanghai exceeded 40°C, and the entire Shanghai city ushered in the first high temperature red warning this year.

This time the heat is global.

Is the 40-degree heat scary?

The temperature in Sicily, a popular tourist destination, reached an all-time high of 48.8 degrees, while the temperature in the northwestern United States and southern Canada even reached a terrifying 49.6 degrees.

If you think that the high temperature of 40 degrees in China is to die for, then think about what the high temperature of nearly 50 degrees in Europe and the United States means.

In a sense, no wonder Europe and the United States like to talk about environmental protection and global warming in the past ten years.

Let’s put Europe and the United States aside first. Although China is far cooler than Europe and the United States, 40 degrees is also a terrible temperature.

It’s really hot to the point of death. Even if you come from a poor family, it can still heat you to death.

In recent days, there have been frequent cases of heat stroke across the country, and many people have died.

Heat stroke is a very scary disease with a mortality rate of up to 70%.

Not only is the death rate super high, but the disease can theoretically hit anyone without even needing you to be infected.

Because this disease is actually heatstroke, but the mortality rate is much higher than that of heatstroke.

What is the difference between heat stroke and heat stroke? How can we prevent this terrible disease?

When humans are in a state of high temperature and high humidity, it will be difficult to dissipate heat. At this time, your body will sweat frantically to try to lower the body temperature.

When you sweat to the point of not enough body fluids and water, your body will stop sweating, the heat dissipation function will stop, and if you are still in this environment, your body temperature will rise rapidly.

When your body temperature rises above 38 degrees, you suffer from heat stroke and lose control of your brain, manifesting as dizziness.

Heatstroke is a trivial matter, just take a break.

Simple heatstroke is a small thing, but there’s a fine line between heatstroke and heat stroke.

After heat stroke, if your body temperature continues to rise to about 40 degrees, the body’s physiological functions will be disrupted, and cells in the brain and organs will begin to slowly die.

Approaching 41 degrees, cells in the brain and organs rapidly die.

In other words, the only difference between heatstroke and heat stroke is body temperature, which is a 2-degree difference.

As long as the body temperature rises by 2 degrees after heat stroke, a person will get heat stroke and the mortality rate is extremely high.

A person with heat stroke has lost the ability to sweat to cool down. As long as he faints, his body temperature will rise by 2 degrees very quickly.

How hot is the ground right now? Although the temperature is 40 degrees, the surface temperature is 60 or 70 degrees.

Some netizens left the ants on the floor under the noon sun, and the ants died within 3 seconds.

A few days ago, a man in Zhejiang was hit by a car, causing a serious car accident. Six ribs were cracked and he fell to the ground on the spot.

As a result, just after waking up from the dizziness of being hit by a car, the man immediately managed to get up from the ground and ran all the way to the shade before lying on the ground again.

I would rather die from pain than to be sunburned.

And a person with 6 broken ribs may not necessarily die, but if you lie on the ground waiting for rescue, waiting for the ambulance to arrive, it is hard to say whether the person is still alive.

Death is bearable, but ripeness is bearable.

It is impossible for a person to suffer from heatstroke in a well-ventilated and shaded place. All environments that can cause heatstroke must be humid and hot. In such a place, as long as the person is in a coma from heatstroke and is left unattended, how long does it take? The body temperature can rise by another 2 degrees in minutes.

Once a person’s body temperature rises from 38 degrees to 40 degrees, the condition develops from heat stroke to heat stroke. Even if HS patients are rescued, most suffer from organ failure and brain damage.

A doctor dissected the body of a heat stroke patient and found that the patient’s internal organs looked as if they had been boiled.

The mortality rate of heat stroke in the hospital is not fixed. It is only 20% low and 70% high. The reason for this gap depends entirely on the conditions before the patient is sent to the hospital.

The death principle of heat stroke is the protein denaturation caused by the high temperature of the human body. As long as the protein of the cell is denatured, the death of the entire cell is irreversible. When the number of dead cells reaches a certain number, the organ will fail. , even the brain fails, and then the person dies.

Therefore, the shorter the time the patient stays in the state where the body temperature exceeds 40 degrees, the lower the probability of death. If the patient is beaten back just after entering 40 degrees, the damage will be almost negligible. .

Therefore, the core focus of heat stroke treatment is to rapidly lower the patient’s body temperature, rather than waiting to be sent to the hospital for emergency equipment.

The ten minutes you wait for the ambulance to arrive is the difference between life and death for a heat stroke patient.

As long as you understand the death mechanism of heat stroke, you will know that the treatment of heat stroke does not require a professional doctor, only the faster the cooling the better.

Doctors can treat organ failure that has already developed, which the average person cannot. But the help of colleagues around you can keep this person’s organs from failing from the start.

I found a few news stories for you to read.

On June 21, a man in Zhengzhou fell into a coma from heat stroke after working outdoors for 2 hours. When he was sent to the hospital ICU for emergency treatment, his body temperature was as high as 42.3 degrees, and he died after the rescue failed.

On July 6, a 49-year-old male patient in Zhejiang Province suddenly passed out from heat stroke while working in the workshop. The temperature of the worker was 40.7 degrees when he was sent to the hospital. After 31 hours of rescue, he died in the early morning of the 8th. died.

On July 10, West China Hospital admitted 3 heat stroke patients in one day, all were male, 2 were outdoor workers, aged 20 and 40, and 1 was 60 years old. Cook in the kitchen. All three have organ failure, one has died, and the rest are being rescued.

There is also a 70-year-old grandmother who did not pay attention to heatstroke prevention. She fell into a coma during her nap and is still being rescued.

Don’t think that you can get heat stroke only if you are exposed to the sun outdoors. As long as you don’t pay attention to ventilation and cooling, you may have heatstroke indoors and outdoors. If you don’t pay attention to it, you will die.

When the above patients were in a coma, everyone thought it was heat stroke, but they didn’t expect to die later.

Because of heatstroke and death, the body temperature is only 2 degrees lower, and in some circumstances, it is very simple to increase the body temperature by 2 degrees.

If the person next to you knows the first aid measures for a person suffering from heat stroke, they will recover quickly in the hospital.

If the person next to you only knows to call an ambulance to the hospital, it is possible that they will not be able to be rescued when they arrive at the hospital.

How to first aid? Here’s what the hospital official said:

◆Help the patient to lie down in a cool and ventilated place, while propping up the head and unbuttoning the underwear to facilitate the patient’s breathing and heat dissipation;

◆Supplement the water needed by the body, preferably light salt water;

◆Use wet towels, ice packs, ice cubes, fans to help cool the patient;

◆Elevate the patient’s feet to help venous return and relieve shock;

◆If the situation is serious, call 120 and send the patient to the emergency department of the hospital as soon as possible.

It looks very complicated, right, I will simplify it for you, explain the principle, and help you remember.

First of all, heat stroke is not a trivial matter. Heat stroke is extremely dangerous, because the environment that can cause heat stroke is very harsh. If the person with heat stroke continues to stay in that environment, it is very likely to develop Heat stroke and death.

Therefore, people with heat stroke should be highly vigilant, and the person should be removed from the original environment as soon as possible and moved to a ventilated and cool place.

In addition, the cause of death from heat stroke is difficulty in dissipating heat and hyperthermia.

Therefore, the principle of first aid is to cool them down immediately, no matter what means you use, the first thing to do is to cool down the body temperature of the person suffering from heat stroke.

Even if it is sent to the hospital for emergency treatment, the first step is to cool down the body temperature, and then talk about other things.

Every extra minute of delay increases the probability of a patient’s death, so instead of waiting to be sent to the hospital for the cooling step, it is better to help him cool down first.

Put it in an air-conditioned room, it is feasible, and blowing a fan is feasible. But the first thing to do is to hydrate the patient.

If the person suffering from heat stroke is still conscious, give him water as soon as possible to restore his sweating function. If the person suffering from heat stroke has lost consciousness, the problem is serious, very serious.

At this point, the ambulance must be called, but he must save his life while waiting for the ambulance.

Lifting a comatose person to an air-conditioned room and blowing a fan will not work in many cases, because the person is heavy and difficult to carry.

Having an air-conditioning fan is the best condition, but what if I don’t have it?

The people around can go to find water, any water will do, as long as it is not ice water with too much temperature difference, and pour it directly on the patient to forcibly cool down.

The first thing to do is to pour it on the head to keep the brains of people suffering from heat stroke from dying, just like many athletes use bottled water to cool their heads in competitions.

If you can find more water, after saving the heatstroke person’s brain, cool his torso and try to keep his internal organs from dying.

If the person suffering from heat stroke is not in a coma, these measures can be dispensed with, and normal and decent routine cooling measures will suffice.

If the person suffering from heat stroke is in a coma and there are no ambulances such as wet towels and alcohol nearby, don’t do nothing, and directly adopt these rude cooling methods, which can effectively increase the survival rate. .

Even if a bottle of mineral water is thrown on you, it can lower your body temperature a little.

Compared to a person’s weight, a bottle of water can evaporate too few calories, not enough, but at least it can increase the probability of survival, which is much better than doing nothing at all.

Following the right to act in a hurry, the real body temperature is too high to a certain level and it can’t come down. I think ice water can be splashed. Ice compresses for heatstroke patients are one of the first aid measures in the hospital. With too little knowledge, just splashing ice water may cause a little problem, but it’s nothing compared to saving a life.

Of course, it would be even better if there was a large amount of tap water at room temperature to flush those suffering from heat stroke. It is sure to be able to cool down successfully. As long as the body temperature can be forcibly lowered, people will be fine. .

Theoretically, if someone is forcibly lowered their body temperature just after entering heat stroke, the mortality rate can be reduced to zero.

But as long as the patient is sent to the hospital to cool down, the mortality rate will jump from 20%, and the slower the delivery, the higher the mortality rate.

If someone around you falls into a coma while working, in addition to dialing 120, remember to cool him down immediately, use all methods, and give as much water as you can, not even water. Splashing water directly when you go in, this simple trick can really save your life.

Heat stroke is not scary. What is scary is that there is no one around to give you an emergency splash of water to cool down.

Also, when you work outside in the sun by yourself, or in an indoor environment with poor ventilation and high temperature and humidity, remember to always have a water bottle next to you.

Once you find that you are not sweating much, and you are dizzy or weak in your limbs, immediately replenish water. If there is no water, you must immediately withdraw from the environment, otherwise the body temperature will rise rapidly in a short time. high, and then heatstroke.

If no one finds out the first time, and stays in that environment, it will develop into heat stroke in a short time, and then die.

Remember, dizziness, weak limbs, and no sweating in a high temperature environment are all warning signs, very dangerous warning signs.

Hope that heat stroke will never be with you and me.

This disease is very scary, but the prevention and treatment are very simple, and the principle is not difficult to understand. There is really no need to die because of this disease.
