air choke

Chokeholds can be divided into two primary categories: "blood chokes" and "air chokes".

Air chokes have been associated with fractures of the larynx or hyoid bone, and are considered less safe than blood chokes to practice.

Most chokeholds featured in combat sports and martial arts are blood chokes, although some air chokes or combinations occur as well.

In Judo terminology, "blood chokes" are referred to as "strangleholds" or "strangles" while "air chokes" are called "chokeholds" or "chokes".

This can be misleading as most holds aim to strangle not choke with the exception of "air chokes" (choking means "to have severe difficulty in breathing because of a constricted or obstructed throat or a lack of air").

Blood chokes can be applied to efficiently cause loss of consciousness, i.e. a choke-out, while air chokes do not usually cause loss of consciousness without prolonged application (though air chokes are used to cause discomfort).
