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 muses, 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.
The common causes of unconsciousness are shock, electric shock, fainting, apoplexy and injury to the brain, sunstroke and heat exhaustion, freezing, suffocation, and poisoning. The first two have already been described and the treatment of any form of suffocation in artificial respiration.
Fainting
Fainting usually occurs in overheated, crowded places. The patient is very pale and partially or completely unconscious. The pupils of the eye are natural, the pulse is weak and rapid. The patient should be placed in a lying-down position with the head lower than the rest of the body so that the brain will receive more blood. Loosen the clothing, especially about the neck. Keep the crowd back and open the windows if in-doors so that the patient may get plenty of fresh air. Sprinkle the face and chest with cold water. Apply smelling salts or ammonia to the nose, rub the limbs toward the body. A stimulant may be given when the patient is so far recovered that he is to swallow.
Apoplexy and Injury to the Brain
Apoplexy and unconsciousness from injury to the brain are due to the pressure of blood on the brain so that they
