Cerebral hypoxia is a form of hypoxia (reduced supply of oxygen), specifically involving the brain; when the brain is completely deprived of oxygen, it is called cerebral anoxia. There are four categories of cerebral hypoxia; they are, in order of increasing severity: diffuse cerebral hypoxia (DCH), focal cerebral ischemia , cerebral infarction ...
Brain ischemia has been linked to a variety of diseases or abnormalities. Individuals with sickle cell anemia, compressed blood vessels, ventricular tachycardia, plaque buildup in the arteries, blood clots, extremely low blood pressure as a result of heart attack, and congenital heart defects have a higher predisposition to brain ischemia in comparison to the average population.
If the alveolar ventilation is low, there will not be enough oxygen delivered to the alveoli for the body's use. This can cause hypoxemia even if the lungs are normal, as the cause is in the brainstem's control of ventilation or in the body's inability to breathe effectively.
These conditions have some similar — and dangerous — symptoms. But dizziness and vertigo are not the same thing. ... your brain may not be getting enough oxygen. Or you may have balance issues ...

In this situation there is not enough oxygen in the alveolar gas to fully oxygenate the blood volume passing through, and P a O 2 will be low. Conversely, an increased V/Q ratio tends to be a consequence of impaired perfusion, in which circumstances the blood supply is insufficient to carry the available oxygen, P a O 2 will be normal, but ...
The hyperbaric oxygen treatment eliminates carbon dioxide from the brain, while the standard oxygen treatment normalizes carboxyhemoglobin levels. Another preventative measure one can take is to be on bed rest and abstain from stressful and strenuous procedures for the first 10 days after an extended hypoxic event.
