Understanding Modern Tourniquets

All tourniquets do the same core job:

They stop life-threatening bleeding from an arm or leg by squeezing the limb hard enough to stop blood flow.

Where they differ is:

• how they tighten

• how easy they are to use under stress

• how small or flexible they are to carry

• how well they work on different body sizes and injury types
