There are several causes of cerebral hypoxia, according to the different causes, to take different conditioning methods, including hyperbaric oxygen therapy, improve circulation, as follows: 1, hyperbaric oxygen therapy: causes of cerebral hypoxia are carbon monoxide poisoning, for carbon monoxide poisoning caused by hypoxic ischemic encephalopathy, treatment methods preferred hyperbaric oxygen therapy, hyperbaric oxygen is the preferred treatment method for carbon monoxide poisoning, with special effects. In the early stage, it is recommended to do hyperbaric oxygen therapy twice a day, to be done continuously, for 20-30 days, the patient’s symptoms of cerebral ischemia and hypoxia can be significantly improved. 2, improve circulation: causes of cerebral hypoxia can also be due to the circulatory system caused by cerebral ischemia and hypoxia, such as cardiac arrhythmia, heart failure, should be taken to correct the heart problem, so as to improve the blood supply and oxygen supply to the brain. In conclusion, the causes of cerebral hypoxia in patients are many, and different treatments need to be taken according to different causes. You can also take some drugs to improve the metabolism of brain cells, such as Idebenone, Microphenols, etc., which can help the metabolism of nerves.
