The inguinal region constitutes one of the most difficult areas in which to control junctional bleeding in trauma. Junctional bleeding occurs in areas of the body that are not easily amenable to tourniquet application.
Proximal compression of the vessels is still the most effective way to achieve haemorrhage control. The AAJT does this by compressing the aorta at or near the bifurcation. Animal studies demonstrate that the device is safe for up to 60 minutes of application. Human studies show that the device is effective at stopping blood flow in the femoral arteries at inflation pressures of 300mm Hg.
