Generally speaking, the plateau reaction often refers to a series of clinical symptoms that occur when the human body rapidly enters into a high altitude area from a low altitude area, the specific mechanism is because the human body is intolerant to the low-pressure, low-oxygen environment of the high altitude area. In terms of clinical manifestations, it is often manifested as the patient’s weakness, palpitation, cyanosis, dyspnea, chest pain, headache, nausea, vomiting and other symptoms in a few hours to a few days after entering the high altitude area, and some of the patients may even suddenly fainted or convulsions, etc. In terms of treatment, for the vast majority of patients, it is a series of clinical symptoms when entering the high altitude area rapidly. In terms of treatment, for the vast majority of patients, often do not need special treatment, only need to give patients appropriate rest, adjust the diet structure, the above symptoms will disappear within 1-2 weeks. However, for people with obvious symptoms, symptomatic drugs can be used to relieve and improve the clinical symptoms, and oxygen therapy can be used as well. For the rare severe plateau reaction patients, active treatment should be carried out to prevent pulmonary edema, cerebral edema and other related serious conditions. For patients whose symptoms are not relieved or worsening, they should be transferred to a lower altitude area as soon as possible for further treatment.
