Anoxic brain injury is a sort of brain damage that isn’t typically brought on by a head injury. Anoxic brain injury, in contrast, happens when the brain is oxygen-deprived. A process known as apoptosis kicks in when brain cells are denied oxygen for an extended period of time. Although cell death is a natural part of life, individuals may have impaired brain function if a significant number of brain cells pass away at once. Anoxic brain damage could result in death if the lack of oxygen persists.
Why Does Anoxic Brain Injury Occur?
A brain injury known as anoxic brain injury can result from anything that deprives the brain of oxygen. Some of the most frequent causes are as follows:
Babies who are born with oxygen deprivation are frequently those that become stuck in the delivery canal or whose umbilical cord is wrapped around their necks.
A terrifying assault or attack, such as being suffocated to unconsciousness.
Having a stroke can deplete the brain of oxygen and blood for a number of minutes.
A transient ischemic attack (TIA), sometimes known as a mini-stroke, deprives the brain of oxygen for a short period of time, usually between a few seconds and several minutes.
Due to allergic responses, and anaphylactic shock.
self-vomiting and swallowing it.
a sudden impact on the windpipe.
How much time can the brain go without oxygen?
It goes without saying that every brain is unique, and the severity of oxygen deprivation varies based on the lesion. Anoxic brain injuries can be caused by a variety of conditions, some of which just diminish oxygen and blood flow while others completely stop it. Since the brain can only go without oxygen for four minutes on average, you must act quickly if you detect a stroke or other damage that is robbing the brain of oxygen.
Brain damage can start as soon as 30 seconds have passed, and two minutes later it is almost certain to occur. Even if you or a loved one feels good following a loss of oxygen to the brain. You should still seek immediate medical attention to lessen the possibility of long-term damage.
