What is hypothermia and how to deal with it?

Hypothermia refers to the hypothermia of the human body, which can cause a decrease in body heat production or an increase in heat dissipation due to a variety of reasons, resulting in a lower than normal body temperature. Clinical manifestations include pale, cold, purple lips or earlobes, heartbeat, breathing can be slowed, blood pressure can be reduced, urine output can be reduced, and in severe cases, the central nervous system function can be impaired and consciousness disorders can occur, and even coma can occur.

Hypothermia, also known as hypothermia and hypothermia, refers to the core body temperature of the human body due to various factors that hinder heat generation and factors that increase heat loss.

Diseases below 35 degrees.

What is the incidence of hypothermia in the population?

The occurrence of hypothermia is regionally and seasonally, which is related to individual factors, health status, medication, and environmental factors. Trauma.

Patients have increased hypothermia prevalence and mortality.

What are the types of hypothermia?

Depending on the cause, it can be divided into primary hypothermia and secondary hypothermia.

Primary hypothermia.

That is, unexpected low temperature, which is caused by a cold environment, the body temperature spontaneously drops to 35 degrees, and the thermoregulatory center is not damaged.

Secondary hypothermia.

It is caused by impaired function of the hypothalamic thermoregulatory center, and patients often have an underlying disease or drug effect.

According to the degree of low temperature, it is divided into light, medium, and heavy

Light: Core body temperature of 32-35 degrees.

Medium: Core body temperature of 28-32 degrees.

Severe: Core body temperature of <28 degrees.

1.Causes: The higher the altitude, the greater the climate change, and when there is a lack of proper thermal equipment, or long-term exposure to the harsh climate of low temperatures, especially when the body's heat loss exceeds the amount of supplemental heat that can be produced in time and when clothing is wet, there will be a physiological response to a drop in body temperature.

When the body temperature drops below 35 degrees Celsius, the human body has entered a state of hypothermia.

2.Symptoms: Feeling cold, ** pale, cold limbs, violent and uncontrollable shaking, slurred speech, unresponsiveness, slow pulse, loss of consciousness.

3.Processing Principles:

Prevent the patient from continuing to lose body temperature and gradually assist the patient to achieve normal body temperature.

When the person is conscious, the person may be given a sweet, hot drink.

4.Processing Steps:

Prevent the patient from continuing to lose body temperature, and gradually assist the patient to obtain normal body temperature, remove the patient from the harsh cold environment, and move the patient to a warm place (tent, house), and if the environment allows, make a fire outdoors for warmth.

Help the patient take off the damp and cold clothing, and wrap the patient's whole body with warm clothes and sleeping bags.

When the patient is conscious, the patient may be given a sweet, hot drink or, if unconscious, lying in a recovery position. The patient may be given a hot water bottle or the rescuer may be given a body temperature conduction to prevent the patient's body temperature from dropping again. If the patient's breathing and heartbeat stop, CPR should be performed and the patient should be sent to the hospital as soon as possible.

Remember not to give alcohol to the patient, not to wipe or massage the limbs, and not to encourage the patient to exercise.

5.Prevention method:

When resting in the camp, you should eat and drink plenty of high-calorie food, and you should wear warm clothing.

Don't build your camp in a windy and cold place.

Hypothermia, also known as hypothermia. A person's normal body temperature is 37, hypothermia is when the victim's core temperature drops below 35, and if the body temperature is below 32, the condition becomes severe and eventually fatal. Hypothermia may be responsible for more direct or indirect deaths than all other factors combined.

Symptoms of hypothermia:

Uncontrollable tremors and inability to warm.

Blurred vision and incoherent speech.

Loss of coordination, loss of sense of direction.

The face and hands are grayish-white, and the muscles go from trembling to stiff.

Inability to perform complex movements, especially if the hands do not listen to calls.

At 32 hours, the body enters"Hibernation"state, which closes blood flow to the arms and legs, dramatically lowers the heart rate and respiratory rate.

At 30 hours, the body enters the metabolism almost stopped"Iceman"The state that the characteristics of life have become difficult to detect, and the patient is easily mistaken for dead. The pupils are dilated and unresponsive. The pulse is not felt.

Breathing is intermittent, with a respiratory rate of less than 4 to 5 breaths per minute, and appears to be dead, but still alive.

Remind everyone that due to insufficient heat insulation, heat will gradually be lost, and the body temperature will drop, and the symptoms of hypothermia will appear. Therefore, it is important to keep warm during the cold winter.

1.Add warm clothing.

In the cold winter months, even at home, it can feel cold, especially late at night when the temperature plummets, so it's important to add clothes at the right time.

2.Reduced heat loss.

Wearing cold and wet clothing, or soaking in water for a long time, will cause the body to lose heat energy quickly, so even after exercise, the body will produce a lot of heat, but if you wear sweat-soaked clothing, it may cause hypothermia. In addition, you must do a good warm-up exercise before swimming, and dry your body immediately after swimming, and change into dry and warm clothes to avoid the heat in your body being quickly depleted.

3.Improves the body's ability to produce energy.

In addition to relying on external forces to keep warm, the most active way is to increase one's own body temperature, such as maintaining exercise habits, which can strengthen blood circulation and metabolic function; Maintain a balanced nutrition so that the body has enough energy to provide the required calories, especially foods rich in vitamin E and C, such as green fish, yellow and green vegetables, beans, citrus, cauliflower, green peppers, potatoes, etc. High-calorie and easy-to-absorb foods can also quickly warm up the body.
