ANSWER: For Each Minute Your Brain Does Not Receive Oxygen, Your Chances Of Living Gets Reduced So A persons brain can live for about 7 Minutes without oxygen Edit Share to:
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. At 10 minutes, even if the brain remains alive, a coma and lasting brain damage are almost inevitable. At 15 minutes, survival becomes nearly impossible. There are, of course, exceptions to every rule. Some training routines help the body make more efficient use of oxygen, enabling the brain to go longer periods without this vital element. Free divers routinely train to go long periods without oxygen, and the current record holder held his breath for 22 minutes without sustaining brain damage!
