As a medical professional with expertise in neurology, I can explain the consequences of oxygen deprivation to the brain. When there is a lack of oxygen to the brain, it can lead to a condition known as cerebral hypoxia. The brain cells are particularly sensitive to such deprivation. If the oxygen supply is cut off, some brain cells can begin to die within as little as 5 minutes. This rapid onset of cell death can result in severe brain damage or even death. read more >>
