Shouldn’t it be bleeding more, or did the explosion cauterize it?
Good question...I know there are cases where there is a traumatic explosive injury, and the body just temporarily spasms off all the blood vessels into the area and there is less bleeding than you might think.
Kind of a built in biological damage control mechanism.
However, with the passage of some time, those vessels relax and blood starts flowing. If measures haven’t been taken (pressure points, tourniquets, clamps) then I believe a patient could be in danger of losing a lot of blood.
My step-son blew off half his hand about six months ago. I was very surprised how little blood he lost.
