$3.2 million for just two shock-related studies A Virginia Commonwealth University study group has been awarded $3.2 million in federal grants for two shock-related research, one with battlefield implications and the other for emergency medicine. The U.S. Department of Defense awarded the VCU Reanimation Engineering Shock Middle, or VCURES, a $1.3 million cooperative agreement to study and design a means for soldiers harmed in combat to survive devastating blood loss when medical facilities are a long way away. And the National Institutes of Health awarded VCURES a $1.9 million grant to study how oxygen is transported by the littlest blood vessels of your body during severe hemorrhage and resuscitation.Israel, M.D., Isabelle C.
