Warning: When using a tourniquet remember that cutting off the circulation for a long time is dangerous. It is much safer not to keep on a tourniquet more than an hour. Loosen it, but be ready to tighten it again quickly if bleeding re-commences.
Another method to stop bleeding from an artery when the wound is below the knee or elbow is to place a pad in the bend of the joint and double the limb back over it holding the pad in tightly. Tie the arm or leg in this position. If these means do not check the bleeding put a pad into the wound and press on it there. If you have no dressing and blood is being lost very rapidly, make pressure in the wound with your fingers. Remember, however, that this should only be resorted to in the case of absolute necessity as it will infect the wound.
Blood from veins flows in a steady stream back toward the heart and is dark in color. From most veins a pad firmly bandaged on the bleeding point will stop the bleeding. If a vein in the neck is wounded, blood will be lost so rapidly that the injured person is in danger of immediate death, so you must disregard the danger of infection and jam your hand tightly against the bleeding point.
Keep the patent quiet in all cases of severe bleeding, for even if it is checked it may start up again. Do not give any stimulants until the bleeding has been checked unless the patient is very weak. The best stimulant is aromatic spirits of ammonia, one teaspoonful in half a glass of water.

Unconsciousness and Poisoning
Unconsciousness, of course, means lack of consciousness, or, in other words; one who is unconscious knows nothing of his surroundings or of what is happening. A person may, however, be partially, as well as wholly, unconscious.
Unconsciousness may be due to so many causes that, in order to give the best treatment, the scout should first know the cause. Always try to find this out if you can. If you cannot do this, however, you should at least determine whether unconsciousness is due to poison, to bleeding, to sunstroke, or to freezing; for each of these demand immediate, special treatment. If it is not due to one of these causes, and the patient is pale and weak, have him placed with his head low, and warm and stimulate him in every possible way. If the face is red and the pulse is bounding and strong, that patient should have his head raised on a folded coat. No stimulants should be given him and cold water should be sprinkled on his face and chest.
