Outdoor classroom: everything from medicine to treatment

First, high altitude mountaineering to prevent physical dehydration

When the human body performs outdoor sports, chest dehydration is very likely to occur at high altitudes, because perspiration (nacl 0.2% in sweat), breathing, urination, and diarrhea can all lead to the loss of water in the body. In the cold mountainous regions, because the air is extremely dry, the body surface evaporates quickly, and at the same time it discharges a large amount of water through rapid breathing movements, but often it is not consciously perceived, resulting in symptoms of dehydration (hypertonic dehydration). For diseases caused by high temperatures, colds, and acute mountain diseases, maintaining good fluid uptake is an important prevention and control measure. Not only can the chance of getting sick be reduced, but also the overall physiological function of the climber can be greatly enhanced.

Body dehydration (hyperosmotic dehydration)

Symptoms: (1) Mild water shortage: thirst. The amount of water shortage is 2~4% of body weight.

(2) moderate water shortage: extremely thirsty, fatigue, urine, dark turbid urine, dry lips and tongue, irritability, poor skin elasticity, orbital deep. The amount of water shortage is 4-6% of body weight.

(3) Moderate water shortage: In addition to the above-mentioned symptoms, hallucinations and delirium occur until coma. Water shortage is about 6% of body weight.

Body dehydration precautions:

(1) Drink plenty of water. Drinking hot tea during camp activities can prevent dehydration and keep warm. Drink a glass of water before starting the journey. Drink enough water (equal drink) every 30 minutes on the way. Daily water intake> 2000 ml/d (camp activity) ~ 3000 ml/d (when traveling).

(2) Drinking water should not be replaced by high-concentration juices or other high-concentration fluids (chocolate drinks, cereals, etc.) during strenuous exercise. Recommended beverages: hot water, tea, low-strength Guozhen beverages, vit.c effervescent tablet drinks or other sports drinks.

(3) At the same time, it is necessary to eat salty nuts or road foods properly to supplement the loss of salt in the body.

(4) Carrying 1l~2l thermos bottles on the way.

(5) The amount of drinking water during the journey must be evenly distributed, fully taking into account the return of drinking water and emergency response.

(6) Do not eat ice and snow, to prevent mouth and throat frostbite. (7) quit smoking, avoid alcohol, reduce spicy, high salt food intake.

Body dehydration treatment:

(1) Drinking water. First consider drinking low concentrations of glucose water or other sugary hot beverages. If necessary, intravenous fluids can be used.

(2) Appropriate supplemental salt (oral rehydration salt granules) and vitamins.

(3) Heat fluid (fruit flesh, chocolate drink) or semi-liquid (porridge, cereal, or rotten noodles) to supplement body energy. If the patient's thirst is relieved, the mood gradually stabilizes, and urination prompts the condition to improve. Consciousness is clear, the answer to the answer, clear urine color prompts the dehydration of the body has been corrected.

Second, field emergency skills - cardiac resuscitation [CPR]

First aid is an emergency treatment that is indicated by a person or other person who points out a sudden injury. The faster the emergency treatment measures for the injured, the better. If you encounter an accident that does not know how to handle it. To ensure that the injured are not life-threatening, do not casually move the injured, otherwise it will make the situation worse. Before the field crossing, each member should receive first-aid training before proceeding.

First aid knowledge

The injured person is in a coma. He should check if his/her heart and lung function is normal. Check the following three steps. If you suspect you have a back or neck injury, you should be careful not to move his/her head and fasten his head as quickly as possible.

Open the mouth of the injured person, remove the obstruction in the mouth, and check the respiratory tract: Place one hand on the forehead of the injured person, and use two fingers of the other hand to lift the chin of the injured person to make their heads backwards. Yang.

Check the victim's breathing. Place the cheek close to the injured person's mouth and nose for about 5 seconds and feel his/her breathing. At the same time, observe the chest movement of the injured person to determine if the injured person's lung function is normal.

Measure the number of pulse pulsations at the trachea to check the blood circulation of the injured person. Measure for 5 seconds. If there is pulse pulsation and breathing, place the injured in a resuscitation position. If there is neither breathing nor pulse pulsation, start the cardiac resuscitation treatment. .

If the victim is unconscious, he or she is best placed in a resuscitation posture so that the victim's tongue does not block the throat and saliva flows out of the mouth to ensure that the airway is open.

If the victim is still awake but still breathing, lift the arm of his depression to the proper place in the body, place the other arm close to his cheek, straighten the legs of the depression, bend the other leg, and injure him. The thighs pulled closer to them and the injured lay on their sides.

Put the head of the injured person on the ground and throw it back. The forward part of the jaw is to keep the airway open. If possible, place the injured person's hand under his head.

Artificial respiration

Oxygen in the air exhaled by people accounts for 16%. By doing artificial respiration, it can promote the patient's blood circulation. If the patient stops breathing but has pulse jumps, do 10 times per minute until the patient can breathe spontaneously.

Let the sick and injured lie flat on the ground. In order to ensure smooth breathing, remove the blockage from the mouth. Put a hand on the forehead of the victim and pinch the nose. The other hand was placed under his chin, with his head slightly tilted back.

Clench the wounded person's nose with your thumb and forefinger and blow the air from the mouth to the patient's lungs for 2 seconds. Then stop blowing. Let the patient's chest treatment completely go down.

Repeat step (2), 10 times per minute until the wounded and the patient can breathe spontaneously. Measure the pulse and if it stops, apply CPR to it.

CPR treatment

CPR therapy can provide artificial blood circulation and inflate the lungs. The effects of this treatment include the promotion of blood circulation to the head and artificial respiration by the chest to maintain blood oxygen levels. The specific method is as follows:

Let the patient lie on a solid surface, use the index finger and middle finger to probe the lowest rib, and then move the finger up until the middle finger touches the junction of the ribs and the sternum.

The middle finger is located at the sternum, and the other hand moves down the sternum until it touches your own index finger and compresses the chest in this place.

Double use overlap, finger interlocking and upward warping, arm straight and press down forcefully, then relax, but do not remove the object. Repeat 2 times after repeating 30 times.

shock

Insufficient supply of oxygen and nutrients by organizations can lead to a decrease in systemic blood flow and shock. If the patient is not treated promptly, his vital organs will stop working and cause death. The treatment for shock patients is as follows:

Raise the patient's legs (slightly above the head) to keep them awake, unfasten the clothing, let the patient relax, and measure the pulse.

Cover sleeping bags or coats on the patient's back and chest. Measure your breathing and heartbeat. Especially when the patient is unconscious, if the breathing and heartbeat are stopped, CPR therapy is performed.

3 Stage Standing Desk

As the name suggests, the Sit Stand Desk is a table that can be raised and lowered, so the lifting function is the biggest feature of this Height Adjustable Table. The lifting column is up and down through the control of the control box. Therefore, the most important part of an Electric Adjustable Desk is the lifting column (including the motor), the control box, and the hand controller. Without one of these three parts, the lifting function cannot be realized. The two lifting columns of the Dual Motor Standing Desk are controlled by two motors, and the stability and fluency of the dual-motors are more prominent among similar products. computer desk
