People in the experiment were deemed unconcious from 1.6 seconds to almost 10 seconds after the choke began. Others were not choked out after 20 seconds. If you held the person who was unconcious after 1.6 seconds for another 8 or 9 seconds, you could cause permanent brain damage or death.
If no CPR is performed, it only takes three to four minutes for the person to become brain dead due to a lack of oxygen. By performing CPR, you circulate the blood so it can provide oxygen to the body, and the brain and other organs stay alive while you wait for the ambulance.
