People who work in a plateau environment for a long time will have some adverse reactions. Because generally working in the plateau above 3000 meters above sea level, it is easy to lead to relatively thin air inhalation, and appear the organism lack of oxygen. Its a long time easily lead to chronic sequelae of plateau reaction, such as will appear different degrees, long-term dizziness, dizziness, chest tightness, especially with chronic respiratory system underlying diseases, such as chronic bronchitis, bronchial asthma, pulmonary heart disease, idiopathic pulmonary interstitial fibrosis, etc.. Long-term work on the plateau will aggravate the state of hypoxia, which will cause hypercapnia and hypoxemia, thus leading to chronic respiratory failure. At this time, early symptomatic and etiologic treatment is needed, such as long-term oxygen intake and taking medications to relieve plateau reactions, such as Rhodiola, Vanzantine, etc., and active treatment of the primary respiratory system of the above diseases.
