Diagnosis of altitude sickness, symptoms of altitude sickness

1.Acute altitude sickness.

When acute altitude sickness enters the altitude of more than 3 kilometers, the symptoms are the most obvious on the first and second days, and then gradually decrease, and most of them basically disappear on the 6th and 7th days, and a few can continue to exist. The main manifestations are headache, memory and thinking ability loss, insomnia, dreaminess, etc. deep breathing, increased frequency, tachycardia.

Some patients have cyanosis and elevated blood pressure.

2.High-altitude pulmonary edema.

People in the plateau with pulmonary edema plain or lowland developed the disease 1 3 days after entering the plateau rapidly, and there were also those who developed the disease later than 7 14 days. The presentation is the same as that of pulmonary edema in general. Worsening dry cough, headache, dyspnea, or cyanosis in patients with acute altitude sickness are early manifestations of the disease.

A small number of fulminant patients present with extreme dyspnea, irritability, or confusion, a large amount of pink frothy sputum, and coarse crackles and wheezing in both lungs.

3.High-altitude encephalopathy.

Most of the symptoms of high-altitude encephalopathy are preceded by acute altitude sickness, followed by obvious psychoneurological symptoms such as severe headache, mental abnormalities, trance, intractable nausea, vomiting, and coma in severe cases. Cerebrospinal fluid examination (CSF) examination only shows increased pressure.

The symptoms of altitude sickness are generally manifested as: headache, shortness of breath, chest tightness, anorexia, slight fever, dizziness, fatigue, etc.

Some people have different manifestations due to low oxygen content: purple lips and fingertips, drowsiness, hyperactivity, and inability to sleep.

Some people have dry air: roughness, chapped lips, bleeding or blood clots in the nostrils, etc.

When you encounter these symptoms at the beginning of the plateau, don't panic too much, let's take a look at the following one, how to prevent these altitude sickness

Most people have mild or severe altitude sickness when they first arrive at the plateau, and there is no rule to follow what kind of people will have altitude sickness, and the best way to avoid or alleviate altitude sickness is to maintain a good attitude to face it. Taking drugs to relieve altitude sickness: plateau rhodiola, Omo blue tablets, American ginseng lozenges, etc., you can take the method of resting, drink more water, and exercise less.

Altitude sickness refers to the physical discomfort caused by the high altitude after a person reaches a certain altitude. When the altitude reaches about 2,700 meters, altitude sickness occurs. So what are the general symptoms?

1. Headache, palpitation, chest tightness, loss of appetite, nausea, vomiting, purple nails and lips, etc.

2. Mental trance and cognitive decline. This can be measured with a calculation problem. For example, it usually takes less time to do a simple calculation problem. But repeating the same question, it takes a long time, which means that altitude sickness is already occurring.

3. Rapid pulse, mildly elevated blood pressure, puffiness of the eyelids and face. These symptoms will be relieved or disappear after 1-2 weeks of rest.

1 Headache caused by altitude sickness is the most common symptom, usually in the forehead and both temporal throbs, and generally worsens at night or in the morning when you wake up.

2. Altitude sickness can cause indigestion, loss of appetite, bloating, and if the reaction is severe, there may be nausea, vomiting and even abdominal pain, and there is a desire to defecate but no diarrhea.

3. Altitude sickness will deepen and accelerate breathing, and due to mild hypoxia, you will feel chest tightness and shortness of breath, and will gradually return to the original level until you adapt to the local environment.

4. Altitude sickness will make consciousness blurred, unable to recognize people, and even hallucinations and obvious lightheadedness in severe cases.

Altitude sickness is mainly manifested as vomiting, tinnitus, headache, fever, loss of appetite, fatigue, fatigue, dizziness, nausea, vomiting, abdominal distention, diarrhea, chest pain, insomnia, dizziness, drowsiness, dizziness, numbness of hands and feet, convulsions, etc. In severe cases, there may be dysesthesia, restlessness, hallucinations, etc., and may also produce characteristics such as edema, shock, or spasms.

The speed of the hike should not be too fast, it is best to pace steadily and cooperate with breathing, and at the same time adjust according to the slope to make the amount of exercise proportional to breathing, especially to avoid rapid breathing. The height of the ascent should be gradually increased, and the height of each climb should be properly controlled to adapt to the environment of reduced air pressure and thin air.

The itinerary should not be too urgent, sleep and diet should be sufficient and normal, and often take short rests, soft exercises and deep breathing can be done during rest to strengthen the circulatory function and high adaptation, and more physical training should be done to strengthen the oxygen uptake function.

Most people can work and live normally, but a few people can't adapt, and their physical and mental activity abilities are impaired to varying degrees, and symptoms appear, which is called altitude sickness or mountain sickness, altitude adaptation insufficiency, altitude adaptation insufficiency, altitude insufficiency, etc.

The higher the altitude, the thinner the air, the lower the atmospheric pressure, and the less oxygen. Hypoxic hypoxia is the most important factor that affects the human body in a plateau environment. The second is that the plateau is cold and dry, which is an additional hair element for pulmonary edema.

The highlands are windy and windy, and high winds impede human activity and increase oxygen consumption, which is an additional factor that leads to fatigue and exhaustion. Other conditions are increased ultraviolet and infrared intensity, unpredictable meteorological conditions, large temperature differences between day and night, sparsely populated, very lonely, inconvenient transportation, and difficulty in fresh food, etc., all of which affect people's physical strength and spirit to varying degrees, making them prone to respiratory tract infections, loss of appetite, malnutrition, vitamin deficiency, etc., and weakening the body's endurance for hypoxia.

The most common symptoms of altitude sickness are: headache, dizziness, shortness of breath, palpitations, lethargy, malaise, usually low appetite, and nausea and vomiting are common. A small number of people can develop mountain pulmonary edema or mountain encephalopathy.

Measures to prevent altitude sickness include:

1. Before entering the plateau, a comprehensive physical examination should be conducted, if there are cardiovascular diseases, bronchial asthma, tuberculosis, blood system diseases, etc., it is not suitable to enter the plateau area; For patients with acute infectious diseases, they should also enter the plateau after **.

2. Implement the "ladder growth" exercise, that is, after rising to a certain height, after a certain period of adaptation, and then further rise; If you are engaged in labor or physical exercise, gradually increase its intensity or load after the body adapts to improve the body's tolerance to hypoxia.

3. On the way to the plateau and at the beginning of entering the plateau, attention should be paid to the diet that is easy to digest, high sugar and high protein, and it is advisable to eat less and more meals.

4. According to the characteristics of plateau climate, attention should be paid to preventing colds, drinking more water, preventing cold and frostbite in winter, and preventing snow blindness in snow.

I've had this book for 9 years, and today I happened to see this content, and I'm ashamed to say! But I feel that it is still easy to understand, so let's learn it with everyone, I hope it will be helpful to travel to the plateau and climb the snowy mountains.

Altitude sickness, including acute and chronic altitude sickness. A series of hypoxic manifestations that occur in the body in a short period of time after entering a plateau from a plain to a plateau or from a plateau to a higher altitude region are called acute altitude sickness. Chronic altitude sickness is the inability of some people to adapt to the long-term continuous adjustment process, resulting in a phenomenon of altitude dysfunction, presenting a series of clinical symptoms.

Chronic altitude sickness is also known as "dysfunction". It is generally believed that if there are still some or all of the symptoms of altitude sickness three months after entering the plateau, it can be regarded as chronic altitude sickness. Symptoms of altitude sickness generally manifest as:

Pain, palpitation, shortness of breath, loss of appetite, fatigue, fatigue, dizziness, nausea, vomiting, bloating, diarrhea, chest pain, insomnia, dizziness, drowsiness, dizziness, numbness of hands and feet, convulsions, etc. Signs include increased heart rate, deepened breathing, mild abnormalities in blood pressure, edema of the face or extremities, and cyanosis of the lips. The clinical manifestations of chronic altitude sickness are varied, and the symptoms can be part of the above manifestations, or most or all of them, and the symptoms appear and appear from time to time, and generally disappear after returning to the flat and low altitude areas, and there are many similarities with the clinical manifestations of acute altitude sickness.
