When does brain damage occur from lack of oxygen to the brain?

Question

I'm curious how long it takes to start causing any brain damage from blood being cut off to the brain, using a choke hold that the police use or some similar thing.

Answer 1

Brain damage can occur within 4 minutes of the brain being completely deprived of oxygen.  However, I doubt a choke hold could COMPLETELY deprive a person's brain of oxygen unless the officer was literally strangling the person.

Answer 2

General rule of thumb is the "Rule of 3" before damage will start to occur.

3 minutes without air

3 days without water

3 weeks without food

It's a GENERAL rule. Not specific to every case.

Answer 3

each person would be different.it would depend on your age size and drive.you can forget making a case against a cop for this.all they will say is that he was in the line of duty.

Answer 4

MINUTES IN 5 YOUR BRAIN IS BADLY DAMAGED IN 7 MINUTES UR DEAD
