As a matter of fact, I put a guy to sleep last night. Methamphetamines, cocaine, ecstasy and a bad attitude. He lasted about 15 seconds before he went out, but the circumstances of the takedown forced me to apply a less than perfect hold. And I generally release before they're actually completely out. They're wobbly enough that we can get them restrained, and that's what matters.
The possibility of brain injury starts immediately. The longer the hold is maintained, the higher the chances of brain injury.
It's possible that a blood choke can dislodge a chunk of plaque, and the person will have a stroke.
It's also possible (though again, it is unlikely) for the hold to cause a tear in the artery, causing the tunica intima to separate from the media. Blood flowing through this tear causes the intima to continue tearing loose from the media. This is a dissection. As the false passage gets bigger, the true passage gets smaller, which obviously is not a healthy thing. Dissections are a surgical emergency.
The more common brain injury from chokes are (as is likely obvious) caused by the simple fact that the hold restricts or halts the flow of blood to the brain. The lack of blood flow leads to tissue ischemia (inadequate oxygen levels), which is what leads to unconsciousness. The thing is, tissue ischemia is also exactly the same thing that happens during a (non-hemorrhagic) stroke. Exactly how long this will take is a crap shoot. If the persons perfusion is marginal to begin with (as can happen with various pulmonary or vascular diseases, for example) then tissue death will occur much sooner.
Within a couple of minutes, it is almost certain that there will be at least some degree of brain damage. How extensive and how significant is unpredictable. They might loose their ability to speak, or they might loose all memory of March 3rd, 1998 between noon and 12:04PM. By the time you reach the 3-5 minute time frame, the chances of having significant brain injury are very high, and death becomes a real possibility.
It's not a statistically valid sample, but in my own experience, I see more people brought to the ER because of strikes than from chokes. It's also true that strikes are more commonly used than chokes, so I cannot say what percentage of fights involving each will result in a trip to the ER. However, the notion that you can (as one poster claimed) apply a "gentle" choke hold is, in a word, idiotic.
"Gentle" because there are chokes that are applied where the person they're being applied on doesnt even know they're being choked. It's also gentle because it puts them to sleep with no damage being done to them.
By your own admission above you state that damage doesn't occur on the person being choked until minutes have passed. A trained practicioner isn't going to hold a choke nearly that long when it only takes usually 5-10 seconds to put someone to sleep with a properly applied choke. So I'm not seeing how my statement is "idiotic". We have a method where you can safely put an assailant to sleep that won't harm either party. How is that not gentle compared to punching or stomping someone on the face?
