There is no authoritative information on how many times hyperbaric oxygen is needed for good results in cerebral contusion. Generally, mild cases need to be done about 10-20 times, once a day, and severe cases may need to be done 30-40 times. Simple brain parenchymal injury while the soft meninges remain intact is called cerebral contusion. At present, there is no relevant authoritative information indicating how many times hyperbaric oxygen is needed for good effect of cerebral contusion injury. Generally speaking, it is believed that patients with mild cerebral contusion may need to do it 10~20 times, once a day, which is about 1~2 courses of treatment. For patients with serious condition, they may need to do it 30~40 times, which is about 3~4 courses, and some patients may need to do it more times. Therefore, it is impossible to generalize about the number of times of hyperbaric oxygen treatment for brain contusion. Doctors will formulate a suitable hyperbaric oxygen treatment plan according to the actual condition, the patient’s physical state and other factors. Hyperbaric oxygen therapy can improve the therapeutic effect of cerebral contusion, reduce the disability rate, improve brain metabolism, and help restore brain function. Patients with cerebral contusion need to actively cooperate with doctors for standardized treatment and go to the hospital for follow-up on time.
