The application of pressure at this point is shown in figure 15-23H. Do not
apply pressure at this point unless it is absolutely essential, since there is a
great danger of pressing on the windpipe, thereby choking the victim.
Bleeding from the lower arm can be controlled by applying pressure at the
elbow, as shown in figure 15-23I.
As mentioned before, bleeding in the upper part of the thigh can
sometimes be controlled by applying digital pressure in the middle of the
groin, as shown in figure 15-23E. Sometimes, however, it is more effective to
use the pressure point of the upper thigh, as shown in figure 15-23J. If you
use this point, apply pressure with the closed fist of one hand and use the
other hand to give additional pressure.
The artery at this point is deeply buried in some of the heaviest muscle
tissue in the body, so a great deal of pressure must be exerted to compress
the artery against the bone. Bleeding between the knee and the foot may
be controlled by firm pressure at the knee. If pressure at the side of the knee
does not stop the bleeding, hold the front of the knee with one hand and thrust
your fist hard against the artery behind the knee, as shown in figure 15-23K.
If necessary, you can place a folded compress or bandage behind the
knee, bend the leg back, and hold it in place by a firm bandage.
This is a most effective way of controlling bleeding, but it is so
uncomfortable for the victim that it should be used only as a last resort.
You should memorize these pressure points so that you will know immediately
which point to use for controlling haemorrhage from a particular part of the
body.
Remember, the correct pressure point is that which is (1) nearest the wound,
and (2) between the wound and the main part of the body. It is very tiring to
apply digital pressure, and it can seldom be maintained for more than 15
minutes. Pressure points are recommended for use while direct pressure is
being applied to a serious wound by a second rescuer. Using the pressure-
point technique is also advised after a compress, bandage, or dressing has
been applied to the wound, since this method will slow the flow of blood to
the area, thus giving the direct pressure technique a better chance to stop
the haemorrhage.
The pressure-point system is also recommended as a stopgap measure
until a pressure dressing or a tourniquet can be applied.
