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.
1 Don't leave an unconscious person alone. Because alcohol poisoning affects the way the gag reflex works, someone with alcohol poisoning may choke on his or her own vomit and not be able to breathe. While waiting for help, don't try to make the person vomit because he or she could choke.  Help a person who is vomiting.
