What determines whether or not someone responds to the cooling protocol used after a cardiac arrest?

Time: How long the brain has been deprived of blood flow carrying oxygen is critical to the recovery. If the amount of time is not too long, the brain can recover with the help of cooling. However, if too much time without oxygen has occurred, the cooling won't make any difference.

Neurological improve: Cooling protocol is a routine procedure after cardiac arrest. You try to slow all metabolism and see the rest leads to recovery. If the patient wakes up and responds appropriately that is a good sign.
