2. Cerebral hypoxia - Wikipedia

   en.wikipedia.org/wiki/Cerebral_hypoxia

   Cerebral hypoxia is typically grouped into four categories depending on the severity and location of the brain's oxygen deprivation: [20] Aneurysm in a cerebral artery, one cause of hypoxic anoxic injury (HAI). Diffuse cerebral hypoxia – A mild to moderate impairment of brain function due to low oxygen levels in the blood.

3. Hypoxia (medicine) - Wikipedia

   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 ...

4. Hypoxemia - Wikipedia

   en.wikipedia.org/wiki/Hypoxemia

   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.

7. Brain ischemia - Wikipedia

   en.wikipedia.org/wiki/Brain_ischemia

   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.
