How long does it take someone to lose consciousness from a choke hold? Google gives you answers that are anywhere from a few seconds to seven minutes.
That’s because there are many different types of choke holds with different positions, focuses, and purposes. They all require different amounts of time to take effect.
The one that takes seven seconds is: the blood choke.
The blood choke is strangulation, where you cut off the blood flow to your opponent’s brain by choking the carotid artery with pressure. The terminology I learned for this one was the triangle choke (confusing, because there’s a separate variant you can perform with your legs) which is decent because it describes the positioning of the arm, but its also called the rear naked choke and others depending on discipline. You form a triangle around your victim’s neck, with your elbow under their chin, and then squeeze. This choke is designed to cut off the blood circulation to their brain. Starving the brain of blood will put your opponent under much faster than starving it of oxygen. You also have a much smaller window on this choke between putting someone under and death.
Keep in mind, this isn’t like putting someone to sleep. When you knock someone out, they usually wake up a few seconds later.
The one that takes seven minutes is: the two hand throat grab.
The two hand throat grab is ironically the least effective choke and one of the easiest to escape from. This is because while the position is more stable than the single hand grab (which is very easy to break), the dual hands get in each other’s way. This choke hold goes directly after the windpipe, squeezing to cut off oxygen to the brain. Seven minutes is a very long time for professional martial combat. Consider that the standard street fight lasts less than thirty seconds. Martial Combat is all about economizing your time efficiently and this choke is not efficient. However, unlike more effective choke holds, it is easy to do. You’re also unlikely to kill your victim with it, unless you sit there squeezing their throat for about twenty minutes. The reason why I say this is because the hands get in the way of each other and don’t completely cut off the oxygen flow. It’s really hard to squeeze the windpipe shut with your fingers. Ironically, it’d be faster to smother them with a pillow.
These are the two (three) big ones most people think of when discussing choke holds. However, chokes aren’t the only way to strangle someone. There are quite a few techniques from the palm strike to the knife hand designed to perform similar functions like closing the carotid artery or collapsing the windpipe.
When considering knockouts, it’s very important to remember that a knockout isn’t the same as putting someone to sleep. Therefore, it isn’t “safe” and consequence free the way a lot of media portrays.
