Hypoxia, a condition where the body or a specific part of the body, such as the brain, is deprived of adequate oxygen supply, can indeed lead to death. The brain is particularly vulnerable to oxygen deprivation. Brain cells begin to die within minutes of the oxygen supply being cut off, and this can rapidly cause severe brain damage or death. Hypoxia can result from various causes, including respiratory failure, carbon monoxide poisoning, drowning, or high-altitude sickness, and it is a serious medical emergency that requires immediate attention. read more >>

Brain cells are very sensitive to a lack of oxygen. Some brain cells start dying less than 5 minutes after their oxygen supply disappears. As a result, brain hypoxia can rapidly cause severe brain damage or death.read more >>
