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.
Prolonged or complete choking results in asphyxia which leads to anoxia and is potentially fatal. Oxygen stored in the blood and lungs can keep a person alive for several minutes after breathing stops. Choking can be caused by: Physical obstruction of the airway by a foreign body.
