What is brain hypoxia?

cerebral hypoxia is a medical term that refers to insufficient oxygen supply to the brain. In a strict technical sense, this term concerns the lack of oxygen in the external region of the brain or the brain hemisphere. In general, however, it is used to refer to any general lack of oxygen to the brain, no matter where there is a specific shortage. The prolonged brain hypoxia kills brain cells because they need oxygen to maintain properly. Long -term brain hypoxia can then lead to severe cognitive and motor damage or even death due to severe brain damage.

There are four main categories of brain hypoxia, organized by severity. The first, diffuse hypoxia, refers to a slight decrease in brain function due to reduced oxygen levels. Focal hypoxia concerns a localized reduction in oxygen levels and is often related to mild stroke or aneurysmus. A temporary ischemic attack, also known as a mini move, is located hypoxia lasting less24 hours, resulting in neurological damage. Massive brain infarction occurs when blood flow to several areas of the brain is stopped; This is also referred to as a stroke.

Symptoms of brain hypoxia may be of physical or neurological nature and tend to differ greatly depending on the severity of oxygen deprivation. In mild cases, individuals tend to prove poor judgment and may generally be inattentive. They may also have engine problems and consider it much more difficult than usually to complete normal actions such as walking and holding objects. In particularly serious cases, the individual may slip into a coma and become completely unrustled to all stimuli and do not know. In severe cases, coma can be accompanied by a complete loss of breathing.

If serious cases of brain hypoxia do not treat immediately, death is likely. In cases where pulse and bltress ood zIt grows normal, but the victim of hypoxia does not respond otherwise, with a complete brain. In such cases, there is no hope of restoring the victim of any semblance of complete and normal function.

cerebral hypoxia can be caused by many different ways. Some causes are related to external factors such as drowning or excessive smoke or carbon monoxide inhalation. This can lead to assault if the normal air flow does not return quickly. Internal factors that can lead to brain hypoxia include stroke, heart arrest, low blood pressure and paralysis of the respiratory muscles.
