Hyperbaric oxygen is effective in the recovery of neurological function, especially for all kinds of postoperative craniocerebral trauma, cerebral infarction or tinnitus. Hyperbaric oxygen is to place the patient in an environment of atmospheric pressure to inhale pure oxygen, so that the oxygen supply to the damaged cells caused by lesions or surgeries is increased to promote the rapid recovery of damaged cells. At present, the role of hyperbaric oxygen therapy in the field of neurological rehabilitation has been widely recognized, mainly for craniocerebral injury, cerebrovascular disease, and surgery-induced neurological impairment of varying degrees. It should be noted that hyperbaric oxygen therapy needs to be started as early as possible, usually about 1 week after brain damage, to achieve better therapeutic results. If there is a need for hyperbaric oxygen therapy, it is recommended to consult a professional doctor at the hyperbaric oxygen department of a regular hospital to formulate a reasonable treatment plan, and do not arrange the corresponding treatment on your own.
