Deep Bleeder Acoustic Coagulation (DBAC)

The goal of the Deep Bleeder Acoustic Coagulation (DBAC) program is to stop bleeding quickly enough to prevent the transition from non-progressive shock to progressive shock, which occurs when the soldier loses 25% of his blood volume. The DBAC system must be able to cover the full range of life-threatening bleeders from the fast bleeder, which causes a soldier to enter progressive shock in 30 seconds, to the slow bleeder, which causes progressive shock in 8 hours. To reach this goal the DBAC program will develop a portable, light-weight, non-invasive, automated system for the detection, localization, and coagulation of deep bleeders that is operable by minimally trained personnel in the combat environment.
