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.
Choking adults. Choking is when your airway gets blocked and you canât breathe properly. When someone chokes, the airway can either be partly or fully blocked. If itâs a mild blockage, they should be able to clear it themselves by coughing. If itâs a severe blockage, they wonât be able to cough so without anyoneâs help theyâll become unresponsive.
