Has anyone ever tried this. I've seen videos of people doing it, going down in like 2 or 3 seconds, then waking up like 10 seconds later dazed and confused. Is it really that simple? Is it really that 'safe' when done properly?Blood choke
A blood choke or carotid restraint specifically refers to a chokehold that compresses one or both carotid arteries and/or the jugular veins without compressing the airway, hence causing cerebral ischemia and a temporary hypoxic condition in the brain. Regardless of whom the opponent is, a well applied blood choke leads to unconsciousness in 8-14 seconds, and if released, the subject regains consciousness spontaneously in 10-20 seconds. Compared to traditional manual strangulation, properly applied blood chokes require little physical strength, and can be applied successfully by a comparatively weak person. Blood chokes are considered safe for practice and application, although being a lethal technique when held long enough. In Judo, no deaths have been attributed directly to the usage of blood chokes.
