A portable compact tourniquet includes a tourniquet strap and a base operably connected to the tourniquet strap. A strap carriage is operably connected to, and linearly translatable relative to, the base. The strap carriage includes a macro strap adjustment member. A screw assembly is rotatably attached to the base. The screw assembly moves the strap carriage away from the base when the screw assembly is operated in one direction and towards the base when the screw assembly is operated in an opposite direction.
