If cardiac arrest lasts longer than three to four minutes, there usually will be generalized damage to the brain. The prompt initiation of CPR certainly makes a huge difference in ensuring that the brain gets an adequate supply of blood and oxygen.

What does alcohol do in the cerebral cortex?
There are several steps that occur when drinking alcohol and the length of time over when the drinking occurs. 1. Alcohol affects the forebrain. The brain relaxes. This is the CEO of the brain. But poor decisions can be made and motor functions are also affected depending on the amount and time. 2. Further drinking shuts down the mid-brain and emotions are out of control. Fights occur, crying, etc. 3. Even more drinking shuts down the brain stem and heart rate drops, complete loss of consciousness can occur and even death.
The loss of which organ results in the fastest death?
The removal of the brain results in the fastest death. Although there are many ways of facilitating death (shooting, poisoning, infection, gassing etc), all deaths are the result of full loss of brain function. Loss of brain function can occur from: - direct damage to the brain: infection, disease or trauma such as shooting or crushing; or - loss of oxygen to the brain: blood loss via injury or shock, blockage to vessels, failure to pump oxygen (heart failure or poisoning).
What complications can occur when mastoiditis is allowed to advance?
