In humans, a massive wave of electrochemical energy release in the brain occurs after oxygen deprivation, known as 'spreading depolarization', which can trigger pathophysiological cascades. Researchers have found that this event is similar to animal studies and that it remains reversible if circulation is restored before nerve cells die.
Using an automated external defibrillator (AED) increases cardiac arrest survival, especially when applied by a bystander before emergency responders arrive. The American Heart Association found that nearly 66% of victims who received a shock from a publicly-available AED survived to hospital discharge.
