It can be considered a chokehold. "Blood choke" https://en.m.wikipedia.org/wiki/Chok...20the%20brain.

A powerful enough choke can possibly crush your larynx (i.e. life-threatening medical emergency). A pure strangle-hold, you can easily regain consciousness from, if released soon enough and proper after-care is given. I will say that "knee-on-neck" position could easily cut off air and bloodflow. When I saw that video, I immediately winced. It's damn effective at control, but it is VERY dangerous.
