I heard Sean Hannity mention the difference between a choke and a head lock today on his radio show. He said he is a martial artist and knows chokes, then he said you attack both carotid arteries at the same time and it takes ten to fifteen seconds. I think very highly of Mr. Hannity but he couldn't be more wrong about chokes and so is most people who study the arts. 1st- it's impossible to choke both carotid arteries at the same time because the angle of attack on the carotid is 45 degree' with one arm or hand on the carotid and the other on the opposite side behind the neck at 45 degree'. 2nd- Most people believe the rear naked choke is a blood choke, attacking the carotid on both sides. The rear naked choke is a trachea choke. A trachea choke cuts off the air and causes the person to pass out in 6-10 seconds(depends on the amount of air in their lungs when choke is applied. 3rd- the carotid isn't a blood choke it works by activating a barol receptor in the neck that regulates blood pressure. When activated the receptor tells the brain the body is experiencing high blood pressure, the brain sends a signal to the heart to slow down and the heart rate drops 20-40 beats per minute causing the person to pass out. The point can be choked or struck as demonstrated in the video. If struck or squeezed lightly the person passes out in 3-5 seconds. If struck or squeezed hard the person passes out in 2-3 seconds. In the video I squeezed for two seconds lightly and my son collapsed to the floor, still awake but unable to get up and attack as we agreed upon in front of the class. When I struck him I did so very easy and yet he was very unsteady on his legs. Panda sensei
I'm sorry to disagree with you Panda, but you couldn't be more wrong. The rear naked choke uses the forearm and upper arm/bicep to scissor both carotids simultaneously - in my experience unconsciousness follows somewhere about 7 seconds from full application, and if roughly doubled, the recipient will likely not regain consciousness (I hasten to add that the second guideline is only from training, not from actual application!) Whilst there may be some occlusion of the trachea (particularly if not correctly positioned) An actual trachea choke is mechanically quite similar to the single carotid choke you are using in the video, which relies on his own shoulder to compress the other side, a variation of which, I have found to be a practicable response to a glass or bottle, in certain circumstances.
Empty hand response to an edge weapon attack. At the end of the video you will see a short demo of what happens when you activate the carotid artery by choke or strike. There is no need to knock a student out to demonstrate the effects, I choked him for 2 seconds and he crumpled to the floor. On the strike, I lightly tapped the point and he couldn't keep his balance.

Was doing front squats and the bar was rested on the carotid artery, passed out in seconds
