recently,

Min Xiaosheng saw such a news,

Shaoxing, Zhejiang,

When a lady played in the drifting scenic spot,

Suddenly, his face was pale, dizzy, and stiff limbs.

It is understood,

At that time, the temperature was 41 ℃,

Everyone thought she had heat stroke,

As a result, she kept shouting cold.

After inspection,

This lady is acute and warm.

The doctor said,

It may be because the clothes are soaked when drifting,

High temperature evaporation took away the heat in the body,

As a result, the body temperature continues to decline,

Causes warmth.

What are the symptoms of their experiences after the warmth?

What should I do if I encounter temperature loss?

How to avoid warmth outdoors?

What is heating? Start a lecture

The temperature loss generally refers to the loss of the human body's heat than the heat supply, which will cause the temperature of the core area of ​​the human body to decrease, and produce a series of symptoms such as tremor, confusion, cardiopulmonary failure, and even eventually cause death.

The so -called human core area here mainly refers to the main organs that maintain life in the brain and torso. This concept is relative to the human limbs and surface skin.

It will feel cold in the early stage of the temperature, the hands and feet are not shaking, and the consciousness will occur in the middle period. In the later stage, it may cause coma and cardiac arrest.

Generally at low temperatures, normal adults may occur for temperature loss more than two hours.

What are the symptoms of their experiences after the warmth?

By severity, heating is divided into three phases: light, medium, and heavy.

The first phase (mild temperature loss): body temperature drops to 32 ° C to 35 ° C.

At this stage, the human body will tremble, numb hands, and unable to complete complex movements; the distal limb blood vessels shrink to reduce the loss of heat; breathing fast and shallow; "goosebumps" on the skin, it is trying to make the hair stand upright and form a separation. Hot layer. The warm -ups may feel fatigue, abdominal pain, difficulty vision, and abnormal urine.

Sometimes the warm -ups have a warm feeling, but in fact this is the signal that will develop to the second phase. A method of testing the degree of testing to the second phase is whether the patient can contact the thumb with the little finger, which is the first stage of muscle stop work.

Phase 2 (moderate temperature loss): body temperature drops to 28 ° C to 32 ° C.

The muscle is not coordinated more obvious, and human actions are more slow and difficult, accompanied by unstable pace and chaotic direction. The shallow skin blood vessels continue to shrink to maintain the temperature of important organs. The warm -hearted person's complexion, the color of the lips, ears, fingers and toes may turn blue. The occurrence of abnormal undressing is the imbalance of the body's own regulation mechanism. The surrounding vascular expansion that has always been shrinking has caused the illusion of short -term "hot".

Phase III (severe temperature loss): body temperature drops to about 28 ° C.

Muscle tremor usually stops. Difficult to speak and slow thinking. The exposed skin becomes blue and muscle coordination ability is almost completely lost, and it cannot walk or even coma. The pulse and breathing slowly slow, the heart rate may occur too fast or the atrial fibrous tremor, which eventually leads to cardiopulmonary failure.

What should I do if I encounter temperature loss when outdoor sports?

If you have a temperature loss in the outdoor, hurry up to perform first aid to the patient!

"The rescue of the warm -ups must not be heated up, and the temperature needs to be warmed slowly." Wang Yizhen, chief physician of the Department of Critical Medicine, Teda Hospital in Tianjin, said that because of severe temperature -loss patients, severe dehydration, body fluids and cell solution The concentration is rising, and the biochemical environment in the body has produced huge changes to adapt to the low temperature environment. If the repetition is too violent, the blood vessels may be expanded violently, resulting in low blood pressure, further reducing the core body temperature, and causing a recovery shock.

Therefore, the best way to rescue the warm -ups is to break away from the low temperature environment and strengthen thermal insulation.

The first thing to do is to make the warm -out -old person no longer exposed to the cold. If it is wet clothes, it will be replaced in time to avoid exuding more calories.

"In the hospital, we will use a 37 ° C re -warming blanket for patients with temperature -stabilized patients. If on -site conditions are not allowed, they can be wrapped in clothes or sleeping bags." Wang Yizhen introduced Concentrated in the core parts, such as neck, armpit, groin. You only need to do passive warmth to prevent freezing. In addition, when warm -up, the hot water bottle should be wrapped in a cloth to prevent the warming from being too fast.

It should be noted that for those who have severe warmth, they cannot be relieved to normal in the wild, and the re -warming can only delay death, so they must be immediately transferred to the hospital for treatment.

When moving to patients with warmth, you must also be careful, so as not to let the warm blood from returning a large amount of cold blood from the epidermis to the heart during the transportation process, causing arrhythmia.

How to avoid temperature loss?

Familiar with local weather before departure, and make appropriate clothing preparations according to the weather conditions.

If you encounter cold weather, do the corresponding windproof protection measures, and do not be exposed to the cold wind. Warm hats, gloves, collars, windbreakers, thick socks, windproof masks, and even wind mirrors are all necessary items for traveling in cold weather. Excessive body organs are exposed, the greater the wind speed facing, and the body heat will accelerate accordingly.

Outdoor activities in cold weather keep your body dry. If you get wet, hurry up to dry clothes.

Choose fast -drying underwear, avoid cotton underwear. Cotton fabrics are sweaty, and it is not easy to export and cause temperature loss.

Pay attention to the increase or decrease of clothing.Many people like to dress thick while walking. They are afraid that they are cold on the road. As a result, they are not far away.Carry enough high -calorie food.

Don't let yourself overdraft, prevent dehydration, avoid excessive sweating and fatigue, food and hot drinks, and replenish body heat at any time is also very useful to prevent warm -out.

Once he encounters temperature loss, it is necessary to go to the emergency department or burning department for emergency treatment in time.
