The second tourniquet may need to be applied above the joint (elbow or
knee) because the body part below the joint (the forearm or leg) has two
bones. The presence of two bones increases the difficulty of collapsing the
artery completely. The body part above the joint (arm or thigh) has only one
bone and, therefore, the artery is easier to compress.
d. Pull the free running end of the Self-Adhering Band tight and securely fasten
it back on itself (figures 5-16 C, D). Do not adhere the band past the windlass clip.
The friction adaptor buckle is not necessary for proper CAT application to an
arm (figure 5-16 J). However, it must be used as added protection when
using two hands to apply the CAT to a leg. To use, route the Self Adhering
Band strap through the fiction adaptor buckle (figure 5-17). This also
prevents the strap from loosening during transport.
e. Twist the windlass rod until the bright red arterial bleeding has stopped
(Figure 5-16 E). Darker bleeding from the veins may continue for a while.
f. Lock the rod in place with the windlass clip (figure 5-16 F).
(1) For added security (and always before moving a casualty) secure the
windlass rod with the windlass strap.
(2) For small extremities, also secure the Self-Adhering Band under the
g. For small extremities, continue to wind the Self-Adhering Band around the
extremity and over the windlass rod (figure 5-16 G).
h. Grasp the windlass strap, pull it tight, and adhere it to the Velcro on the
windlass clip (figure 5-16 H). The CAT is now ready for transport (figure 5-16 I).
