What is a cerebral infarction stroke?

Stroke refers to ischemic necrosis of localized brain tissue caused by vascular occlusion due to impaired blood supply to the brain. Common causes include cerebral thrombosis, cerebral embolism, etc. Atherosclerosis is the most common cause of cerebral thrombosis. Cerebral embolism refers to foreign emboli embolized in the cerebral artery through blood circulation, resulting in brain dysfunction in the corresponding blood supply area.

Stroke can cause dizziness, hemiplegia, aphasia, sensory impairment, etc. in patients, all of which are manifestations of brain function impairment or loss in the corresponding infarcted area. The fundamental cause of these symptoms is ischemia and hypoxia of the infarcted brain tissue.

When an acute stroke occurs, timely use of a hyperbaric oxygen chamber for hyperbaric oxygen therapy can have a very significant effect. Once a stroke is diagnosed, hyperbaric oxygen therapy should be used. The earlier the treatment, the better the effect.

The therapeutic mechanism of hyperbaric oxygen therapy for stroke recovery:

1.  Improve blood oxygen partial pressure, oxygen diffusion rate, and effective diffusion distance, increase blood oxygen content and tissue oxygen storage, improve blood supply to the affected tissue of cerebral infarction and stroke, and improve the hypoxic state of brain cells.

2. Hyperbaric oxygen therapy can alleviate cerebral edema, lower intracranial pressure, and thus block the vicious cycle from hypoxia to cerebral edema.

3. Promote capillary neovascularization and collateral circulation formation, allowing hypoxic nerve tissue to regain oxygen supply.

4. Reduce blood viscosity and inhibit platelet aggregation; Enhance the activity of fibrinolytic enzymes, promote the dissolution and absorption of blood clots, and improve cerebral blood supply microcirculation.

5. Hyperbaric oxygen therapy can protect mitochondrial function, increase adenosine triphosphate (ATP) content in brain cells, improve energy metabolism in brain tissue, restore normal metabolism of brain cells, and promote the recovery and regeneration of nerve cells.

6. Through hyperbaric oxygen therapy, the damage caused by cerebral ischemia-reperfusion can be reduced, the function of the ischemic penumbra can be restored, the release of excitatory amino acids can be inhibited, the secretion of nitric oxide can be regulated, and the damage caused by free radicals can be reduced.
