The main symptoms of cerebral hypoxia are neurological symptoms, such as dizziness, headache, drowsiness, etc., and the treatment methods mainly include oxygen intake and fluid rehydration. 1. Symptoms: Clinical symptoms caused by abnormalities in the nervous system mainly include dizziness, headache, tinnitus, dizziness, drowsiness, nausea, vomiting, slow reaction and brain swelling. 2. Treatment: The treatment of cerebral hypoxia varies depending on the cause. If it is caused by atherosclerosis and other reasons for the formation of cerebral vascular stenosis, it is necessary to improve cerebral vascular circulation, such as the use of aspirin and other antiplatelet drugs, ginkgo biloba extract and other medicines to activate blood circulation and remove blood stasis. If necessary, interventional stenting can be used. If the cerebral hypoxia is caused by carbon monoxide poisoning, oxygen needs to be inhaled, and hyperbaric oxygen therapy can be used if possible. There are also respiratory diseases, heart diseases, including pneumonia, chronic obstructive pulmonary disease, heart failure, etc., which may lead to cerebral hypoxia, and require low-flow oxygen and active treatment of the original disease. Patients with cerebral hypoxia need to go to the hospital as soon as possible for timely and effective treatment, which may be life-threatening if delayed.
