A strange request . . .

[Roberto1966]

Hi.

I'm Roberto from Italy.

My request it's not pretty medical o about health, and i apologize if i disturb here.

I'm a martial arts practitioner - Kempo - and i wonder to know this: how much pounds of pressure of force developed by a single strike are enough to crush the windpipe (NOT the adam's apple!)
I heard a lot of answer in my life, from 5 pounds to 150 pounds, ecc. and i'd like to know the real truth . . .

Thanks for your attention, ciao!

Hi, Dr. Anitha, thankyou for your kindness.

No, i'm not going to write anything, i'm not a writer.

As i said i'm a Ryukyu Kempo I° dan black belt, and i always was interested about scientific proof to know how force is needed in order to stop an assault.

Now i'm satisfied, and again i want to thankyou for alla these precious informations i was looking for.

Kind regards from Italy, ciao!
Roberto

Hello and hope you are doing well.

Think you're researching or writing a novel. If its a knife, its a clean slit, the trachea is accessible right above the sternal notch, where it is just below the skin. Weight to crush could be 10 pounds. Pressure is usually measured as pascals.

Hope this helped and do keep us posted.

Hi, Dr. Anitha.

Ok, for the pressure instead of weight, i also think this is the right kind of measure to use in this particular case.

What i'd need to know now is the amount of it - if possible, obviously! -  like " it takes 10 pounds of force/pressure to crush the tracheal rings" or so . . .

Thanks for your help, see you soon.
