A faint is a brief loss of consciousness of no more than momentry duration
caused bya a temporary reduction in the flow of blood to the brain. Recovery
is usually rapid and complete.
It may be a nervous reaction to pain or fright; or the result of an emotional
upset, exhaustion or lack of food. It is, however, more common after long
periods of physical inactivty, especially in warm athmospheres, where lack
of muscular activity causes a large volume of blood to collect in the lower
part of the body and legs. This reduces the amount of blood available to the
circulation, eg as in a soldier standing on parade.

SYMPTOMS
- Pulse will be slow at first and weak.
- Casualty may be very pale.
AIM
Position the casualty so that gravity helps increase the flow of
blood to the brain.
NOTE: To prevent fainting, advice casualty to flex the leg muscles and
toes to aid circulation. If the casualty feels unsteady, sit her down
and help her to lean forward with her head between her knees and advise
her to take deep breaths.
