When oxygen can't get to your brain, it begins to starve. During this process, brain cells die, leaving you with injuries that few can predict. If you go too long without oxygen, the damage can result in a coma or death.
Permanent brain damage is difficult to live with. For some, it means relearning how to talk to move. For others, it could mean being unable to do the things they once loved ever again. Anoxic brain injuries, which are caused when no oxygen is reaching the brain, and hypoxic brain injuries, those caused when the brain doesn't get enough oxygen, can be caused by a number of disorders and injuries. For instance, if you're strangled, you could suffer from hypoxia and eventually an anoxic brain injury. If your child is cut off from oxygen during birth, he could suffer permanent brain damage as a result.
