At the battle of Shiloh in the American Civil War, Confederate General A. S. Johnston was killed when he was shot in the thigh. Witnesses reported that he bled to death almost before he realized that he was wounded
Which blood vessel was most likely to have been injured? Why is a tourniquet usually ineffective in stopping the bleeding from this wound?
What will be an ideal response
The wound severed his femoral artery, the largest artery serving the lower limb. A tourniquet may be ineffective because it is a high-pressure, deep artery with a large diameter. It is therefore difficult to exert enough pressure through the thigh muscles to stop the bleeding.
