The indications of hyperbaric chamber in neurosurgical diseases mainly include: first, cerebral infarction, hyperbaric oxygen can improve tissue hypoxia, restore the physiological feedback function of blood vessels, make blood vessels dilate, increase blood flow, enhance the activity of cellular ATPase, so as to effectively improve cerebral microcirculation, which has a very important role in the treatment of cerebral infarction; second, cerebral hemorrhage, hyperbaric oxygen can improve blood rheological index, reduce blood viscosity It also has the function of reducing intracranial pressure; Third, cranial brain injury, hyperbaric oxygen can increase the aerobic metabolism of brain tissue, reduce intracranial pressure and reduce cerebral edema; Fourth, migraine, hyperbaric oxygen can improve brain circulation, improve the metabolism of brain tissue, correct phytocerebral dysfunction in order to relieve intracranial vascular spasm, so as to achieve the purpose of treatment; v. tremor palsy, by improving the hypoxic state of brain tissue, the nerve fiber function of the degenerative damaged substantia nigra and substantia nigra-striatal pathway can be restored, so as to achieve the purpose of treatment.
