Hyperbaric oxygen for patients with cerebral infarction can relieve the symptoms of cerebral ischemia and hypoxia and improve brain function. Patients with cerebral infarction are mainly due to the obstacle of blood circulation in the brain, ischemia and lack of oxygen cause ischemic necrosis of local brain tissue, thus producing corresponding hemiparesis, sensory impairment and other symptoms. Hyperbaric oxygen therapy can allow patients to increase the oxygen content of the body faster, improve the blood supply of the brain, relieve the state of cerebral ischemia and hypoxia, so that the brain dysfunction can also be further improved. It has certain therapeutic significance for patients with cerebral infarction, in addition to which, patients should actively carry out thrombolysis as well as antiplatelet agglutination treatment to stabilize the condition. It is recommended that patients should be treated according to the doctor’s advice, and the specific treatment plan is different for each patient’s own situation.
