It’s an agonizing process that doesn't always work — if bleeding hasn't
stopped after three minutes of applying direct pressure, the medic must
pull out all the gauze and start over again. It’s so painful, “you take
the guy’s gun away first,” says former U.S. Army Special Operations
medic John Steinbaugh.
Even with this emergency treatment, many soldiers still bleed to death;
hemorrhage is a
leading cause of death on the battlefield. "Gauze bandages just don't work for anything
serious," says Steinbaugh, who tended to injured soldiers during more
than a dozen deployments to Iraq and Afghanistan. When Steinbaugh
retired in April 2012 after a head injury, he joined an Oregon-based
startup called RevMedx, a small group of veterans, scientists, and
engineers who were working on a better way to stop bleeding.
