You may use a rolled compress, battle dressing, or
bandage as a pressure pad. If the materials are not
available, you may use any round, smooth pressure
object, such as a rolled handkerchief, a flat stone, or a
rifle shell. If no pressure object can be found, apply the
band without it.
You may use any long, flat material, (i.e., bandage,
belt, stocking, strip of rubber, or necktie) as the
tourniquet band. The band must be flat. Narrow
materials such as rope, wire, or string should not be
used; they will cut into the casualtys flesh.
Most Navy emergency medical kits contain a
webbed band with a buckle on it. The band is tightened
by pulling one end through the buckle. This eliminates
the need for a separate device to tighten the band. If you
are using another type of band, you may use a small,
short stick to tighten it.
There are some general rules to keep in mind when
applying a tourniquet. Apply it over a main artery
between the wound and the main part of the body.
Apply the tourniquet as close to the wound as possible,
making sure that the tourniquet is not touching the
wound and that it is not placed over a joint. Once a
tourniquet is correctly applied, only experienced
medical personnel may loosen or remove it. Refer to
figure 13-6 and use the following steps to apply a
1. Place the pressure pad or similar pressure object
over the main artery supplying blood to the injured
extremity (see A in fig. 13-6).
Figure 13-6.Steps in tourniquet application.
2. Wrap the band once around the extremity and
over the pressure pad. Place a short stick on the crossing
band (see B in fig. 13-6).
3. Knot the band over-the-stick (see C in fig. 13-6).
4. Twist the stick to tighten the tourniquet just
enough to control the flow of blood. Do not make it any
tighter than necessary. A tourniquet that is too loose will
not control the bleeding; one that is too tight may further
injure the extremity.
5. Tie the stick in place with a strip of bandage or
other material (see D in fig. 13-6).
If bleeding fails to stop after the band has been
tightened, there is a good chance the pressure pad is not
placed directly over the artery. If this is the case, loosen
the tourniquet and reposition the pad.
After you have brought the bleeding under control,
place a sterile dressing securely over the wound. Do
not cover the tourniquet with a dressing. Do not
loosen the tourniquet. Again, once a tourniquet has
been correctly applied, only experienced medical
personnel may loosen or remove it.
After placing the dressing, treat the casualty for
shock. Finally, complete the field medical card. In
addition, write the letter T and the time the
tourniquet was applied (e.g., T-0830) on the casualtys
forehead. Use a skin pencil, colored antiseptic, ink, or
crayon for this purpose.
Review the shock section in chapter 9, Dental
Technician, Volume 2, NAVEDTRA 12573, for
causes, signs, symptoms, and treatment of basic shock,
fainting, anaphylactic shock, and insulin shock.
Shock may develop at the time of the injury or
hours later. Never put off treating a casualty for shock
until the signs and symptoms appear. Begin treatment
immediately. If shock has not yet developed, the
treatment may prevent it from developing. If shock has
already developed, the treatment may prevent it from
