(3)
Place the windlass on top of the half-knot.
(4)
Tie a full knot (square knot) over the windlass (figure 5-20).
Figure 5-20. Securing the rigid object with a full knot.
(5) Twist the windlass (figure 5-21) either clockwise or counterclockwise
until the tourniquet is tight and the bright red bleeding has stopped. Bright red blood is
from a severed artery. Generally, darker blood is from a vein. Dark blood may continue
to ooze even after the tourniquet has been properly applied. There should be no pulse
below the tourniquet.
Figure 5-21. Twisting the windlass to tighten the tourniquet band.
(6) Wrap a piece of material (cravat, torn strip, and so forth) around the
limb. Then wrap the ends of the material around one end of the windlass so that the
tourniquet band will not unwind.
(7)
Tie the tails of the securing material in a nonslip knot (figure 5-22).
NOTE:
Tape from your aid bag can be used to secure the windlass instead of a strip
of material or cravat.
