HEMORRHAGE
The novel LAVA TQ is non-inferior to a traditional windlass-rod CAT in occluding blood flow in human legs. For skilled users, the CAT has proven effective at stopping life-threatening hemorrhage in limbs, and the LAVA TQ is equally effective in occluding blood flow in this experiment in human limbs. While the primary anticipated benefit of the LAVA TQ is enhanced usability compared to the CAT, it is essential to document the device’s performance in occluding blood flow. The use of handheld Doppler ultrasound for measuring blood flow has been validated previously.Tourniquets are now widely recommended for use by the public as the first-line treatment for life-threatening extremity hemorrhage.While the difference in pressure applied to the limbs when applying either device was not statistically different in this study, other studies have demonstrated significantly higher application pressures for CAT.
