How the Body Responds to Blood Loss (pkg)

September 4, 2013

It can be a classic occurrence, especially at weddings. A member of the wedding party starts to wobble and sway, then before you know it they’ve fainted and fallen to the floor. A number of factors can contribute to this, the main one being that when you stand rigidly still, blood 'pools' in your legs away from your heart and brain ... so you faint. The same sort of thing happens when accident victims or wounded soldiers lose blood from internal injuries. They’re fine for a moment then they crash. Researchers at Mayo Clinic are teaming up with the U.S. Department of Defense to study the issue in hopes of developing monitoring devices that can eventually save lives.  [TRT 2:17]
