Air choke vs blood choke

[100%Jiu-Jitsu]

Looks like I was essential right:

100JJ, that follows what I was told, the barometer nerves the one that monitors the decrease in blood flow.

Shun, yeah you have to attack both but how does that pertain to what I asked?

You have to crush both carotids to make someone pass out from a blood choke.

This isn't quite true. It will work one sided if you put enough pressure. I did it once as an experiment, and the guy passed out cold because he thought it would never work.

I believe one sided works for the same reason striking someone in the same spot on the neck works -- it's a nervous system response more than actual blood flow being cut off.

Sorry, I misunderstood. I thought you meant that the choke DIRECTLY put pressure on a nerve.

I think the vagus and glossopharyngeal nerves are responsible for monitoring blood pressure in the brain. But I'm not sure, and it's really not important to the RNC, because something is clearly being affected by the decreased pressure.

Interesting, never seen it happen before and have had lots of times rolling where one side was locked but the other open and I was able to stall and eventually escape the choke because of it.

How did you do it while ruling out the possibility of pressure on the other side?

I misread, didnt' realize you were talking about both sides of one carotid body instead of both sides of the neck, ie both carotid bodies.

Barometer was just the term my friend used to explain it to drunk me, it's probably the same nerves you are talking about

Is this not only cutting off one side?

Baroreceptors act like barometers in that they collect data about pressure if it makes you feel any better.

It was a few years ago, but I think I did a one handed cross choke from the guard.

It wasn't a live roll. It was a set up experiment to see if it would work. I got to set my choking wrist up perfectly on the one side, and the idea was to see if I could make him tap with just that.

It was much less efficient than a two sided choke, but eventually he just fell down into my guard limp and started snoring. He passed out before I tired out I guess.

I've also seen an instantaneous choke out from the triangle being applied full force (squeeze explosively as hard as possible and crank down on the neck). You'll also see knockouts from people getting punched/kicked in the neck on one side in the same spot that you put your wrist bone in a choke.

I don't think so; the wrist/forearm is compressing one side while the collar of the gi compresses the other.
