HOUSTON (July 1, 2014) One of the world's oldest and most easily used medical tools is making a comeback on American streets, as police officers in many big cities including Dallas and Houston begin to carry tourniquets after more than a decade of war in Iraq and Afghanistan showed how a simple, 20-second procedure could save lives.
The tourniquet stops bleeding by compressing limbs and squeezing blood vessels shut.
It fell out of favor during the Civil War, when men lay on the battlefield for days and a tourniquet equaled amputation, but quick battlefield evacuation has changed that.
Boston adopted tourniquet kits after last year's marathon bombing and Los Angeles, New York and others are in the process of adding tourniquets to their standard equipment.
