The original reaction refers to the fact that after reaching a certain altitude (mostly above 2700 altitude), due to changes such as air dryness, ultraviolet radiation, and cold, the body is difficult to adapt to the pressure difference at altitude, and the oxygen content is low, which can cause a series of symptoms and functional metabolic changes, which is the most common species of the original disease.
The main symptoms of the original reaction are headache, dizziness, dizziness, sounding, insomnia, fatigue, and even chest tightness, dyspnea, nausea, vomiting, panic, edema and other symptoms.
The higher the altitude, the more the incidence of the original reaction.
Usually when the altitude is reached around 2700, there is a prima reaction.
Patients with respiratory insufficiency, organic diseases, cerebral diseases, pressure sickness, chronic obstructive pulmonary disease, interstitial lung disease, severe poverty, gastrointestinal diseases, as well as patients with neurological and psychiatric diseases and severe chronic diseases are susceptible to altitude sickness and should not go to high altitudes.
The primary reaction can be divided into acute and chronic according to the course of the disease.
Acute reactions
More commonly, if a group that has not adapted to the original environment enters the original area, an acute agent reaction will occur at 6 24 hours. Patients often have clinical manifestations such as nausea, nausea, vomiting, and pain in the double frontal area, in addition to palpitations, chest tightness, shortness, cyanosis of the lips and nail beds. If patients present with central nervous system symptoms, they are usually similar to those seen with excessive alcohol consumption. Most patients experience gradual relief or disappearance of symptoms after 24 48 hours in the original area. However, a small number of patients may be more seriously ill and will develop protopulmonary and cerebral tumors.
SlowAltitude sickness
If the acute primary reaction lasts for more than 3 years and does not recover, it is a chronic original reaction, and the patient manifests as headache, dizziness, insomnia, palpitations, shortness, lack of desire, dyspepsia, numbness, facial swelling, memory loss, inattention, etc., and sometimes even arrhythmia or transient syncope.
If the original reaction has occurred, the clinical manifestations of different patients should be distinguished, and attention should be paid to the symptomatic observation of the disease**.
Patients with mild symptoms should receive symptomatic oxygen as soon as possible**. Moderate and severe patients can take intermittent oxygen inhalation through a flow catheter or hood, and when serious reactions such as brain swelling and pulmonary emphysema occur, they should be rescued on the spot and ventilated with assistance.
Patients with mild original reactions can be cured, and after the appearance of symptoms, they should be diagnosed early and actively, so as to prevent the disease from progressing.
However, if it is not timely, not only will the original reaction time be delayed, but also may be secondary to the original lung and encephalopathy, which is life-threatening.
Therefore, it is recommended that such groups, in addition to conducting a full physical examination and physical exercise in the original area, should also learn the corresponding knowledge and know how to avoid the occurrence of the original reaction and how to deal with it, so as to alleviate the emotion of worry and fear.
How to prevent altitude sickness?
1. A complete physical examination should be carried out before entering the original area, and pregnant women, patients with high blood pressure, epilepsy, severe neurasthenia, active peptic ulcer and severe poverty should not enter the original area.
2. Avoid deliberate exercise before entering the original body, and stop training in the first half of the original to avoid increasing oxygen consumption, increasing the burden of viscera and causing original reactions.
3. When a cold patient enters the original area after the cold has been cured, the body function of such patients is destroyed, and the disease resistance is weakened, and the original disease is very easy to turn into other original diseases, especially lung swelling.
4. Avoid strenuous exercise and heavy work when you first arrive in the original area, and gradually increase the amount of exercise according to the degree of adaptation in the future.
5. Do not overdrink in the original area, do not drink alcohol and smoke, eat more vegetables and fruits, supplement vitamins, and drink a lot at the same time.
6. Try to take less or no baths when you first enter the original to avoid cold and excessive consumption of the body.
7. Pay attention to keeping warm, add materials to avoid cold, reasonably adjust the work and rest time, and keep full sleep.
8. Pay attention to sun protection, wear UV protection glasses, wear a deep shirt, wear a wide-brimmed hat, and apply sunscreen before going out.
9. There will be different degrees of dizziness, dyspnea and other hypoxic reactions when you first arrive, and severe cases will have headaches, muscle aches, insomnia and other symptoms.
10. Maintain a good attitude, have a correct understanding of the original environment, and do not be overly nervous.
11. It is best to choose transportation equipment such as automobiles in the original area, because the faster you reach the original area, the more likely it is to have an acute original reaction.
