TULSA, Oklahoma - A person who has been strangled can be unconscious in seconds and dead within minutes, which is why it’s now being recognized as one of the most lethal forms of domestic violence.

Strangulation is so crucial that when you go to the Family Safety Center, the four critical questions they ask are: are you bleeding, are you pregnant, are you having chest pains, have you been strangled?

Strangulation puts pressure on the carotid artery or jugular which control blood flow to and from the brain. Stopping that blood flow can cause death in four to five minutes.

When a victim survives, the damage may not be apparent until days or weeks later – blood clots, a stroke, even brain damage.

Plus, if a person will strangle you, research says they're seven times more likely to kill you at some point in the relationship, yet it happens all the time.

"Here in the safety center, we see, it's higher sometimes than others, but, in one month, we'll have 80 to 90 percent of the patients have a history of strangulation," said Kathy Bell with Family Safety Center.

In addition to the physical damage, strangulation causes emotional trauma.

Any form of domestic violence should be reported, but experts say if you've been a victim of strangulation, it's critical you get help right away.
