Alpine sickness
The reason for the formation of mountain sickness is that the higher the altitude, the thinner the air and the lower the air pressure, so the oxygen pressure required by the human body also decreases, but the oxygen required by the human body The content remains unchanged. In order to maintain the oxygen content required by the human body in the blood, it is necessary to increase the content of red blood cells, but it takes several days for the human body to automatically increase the content of red blood cells. Therefore, when you first enter the mountain, the height will suddenly increase. , the human body has no time to adapt, and the oxygen supply in the body is insufficient. The higher the height, the shorter the transition time, the more severe the reaction. This physiological reaction is generally called [altitude sickness].
Symptoms of mountain sickness include: vomiting, tinnitus, headache, shortness of breath, loss of appetite, fever, drowsiness, and in severe cases, sluggishness, emotional restlessness, hyperactivity, thinking ability, memory Loss of strength, abnormal hearing, sight, smell, taste, hallucinations, etc., edema, shock or spasm may also occur. The prevention methods are: the climbing speed should not be too fast, it is better to keep a steady pace, and cooperate with the breathing, and at the same time, it should be adjusted according to the rapidity of the slope, so that the amount of exercise is proportional to the breathing, especially to avoid rapid breathing. The height of ascent should be gradually increased, and the daily climbing height should be controlled to adapt to the low air pressure and thin air in the mountains. The itinerary should not be too urgent, the sleep
and diet should be adequate and normal, and frequent short-term breaks should be taken. During the rest, use soft exercises and deep breathing to strengthen the circulation function and height adaptation. Usually, more physical training should be done to increase the oxygen intake function.
First aid methods for altitude sickness: Oxygen and altitude reduction are the most effective first aid treatments. If shock occurs, priority treatment should be given, and attention should be paid to hypothermia and other complications. Rest immediately, move the patient to a place without wind, and take pain relievers if the pain is severe. If still unable to adapt, the height needs to be lowered until the patient is comfortable or the symptoms are significantly relieved. Generally speaking, patients with mountain sickness can recover without treatment after they are lowered to the ground. Even so, severe cases still require medical attention.
