Cerebral hypoxia occurs when there is not enough oxygen getting to the brain. The brain needs a constant supply of oxygen and nutrients to function. Cerebral hypoxia refers to the largest parts of the brain, called the cerebral hemispheres. However, the term is often used to refer to a lack of oxygen supply to the entire brain. In cerebral hypoxia, sometimes only the oxygen supply is interrupted. This can be caused by: Breathing in smoke (smoke inhalation), such as during a fire.
Types of Hypoxia. As noted above, there are different types of hypoxia, or reasons that there is not enough oxygen in the tissues of the body. Hypoxic hypoxia (hypoxemic hypoxia) â- In this type of hypoxia, the tissues do not have enough oxygen because there is a lack of oxygen in the blood flowing to the tissues.
