WOUNDS.
On the use of the Tourniquet or Bandage, and manner of stepping violent Bleedings.
IN treating of the management of wounds the first thing that demands our consideration is the bleeding with which most of them are attended. When the blood is not poured out with great force, though the quantity should even be considerable, it generally proceeds from wounded veins, and may be stopped by pressing a piece of scraped lint, either alone or dipped in fine flour or Turlington's Balsam, upon the wound with the fingers. But when the Hood is thrown out with great force, and especially if it springs out by jerks, it proceeds from wounded artcries, and requires the most serious attention.
To direct us in this case, we must consider the arteries as strong branched pipes or tubes through which the blood is forced from the heart at each beat to every part of the trunk of the body, to the head, to the arms, and to the legs.— The veins spring in small branches from all the parts the arteries carry blood to; they pursue their course towards the heart; joining with each other, forming gradually larger and larger veins, till they reach the heart in one large trunk. The heart may be compared to a sort of forcing pump, throwing the blood along the arteries with such force, that we can feel the jerk or pulse wherever an artery lies: and the blood losing its impulse as it passes along, makes its way, without any pulse or beating, into the veins, through which it returns to the heart, compleating what is called the circulation of the Hood.
From these simple principles the method of putting a stop to a bleeding from a wounded artery is exceedingly plain; that is, it must be compressed between the heart and the wound.
