Detailed explanation-1: -Time is very important when an unconscious person is not breathing. Permanent brain damage begins after only 4 minutes without oxygen, and death can occur as soon as 4 to 6 minutes later.
Detailed explanation-2: -Between 30-180 seconds of oxygen deprivation, you may lose consciousness. At the one-minute mark, brain cells begin dying. At three minutes, neurons suffer more extensive damage, and lasting brain damage becomes more likely. At five minutes, death becomes imminent.
Detailed explanation-3: -When the brain goes longer than five minutes with low oxygen it can cause: Coma (a deep state of unconsciousness) Seizures (uncontrolled unwanted movements, sensations, or behaviors) Brain death (when there is no measurable activity in the brain)
