BLOOD

may be from an artery, a vein or a capillary. In arteries the blood flows from the heart and escapes from a wound in a bright scarlet intermittent stream; in veins the blood flows to the heart and ore in a dark continuous stream; in capillaries the blood is flowing from art erics to veins and escapes as a steady oozing. Owing to these facts it is widely taught that Aico, phil te should be arrested by compre ion of the wounded artery at a a ts nearer e heart, whilst venous hemorrhage should treated by pre ure over the vein further from the heart than the wound. The writer has seen so many amateur attempts at this method sent to the casualty room, which have been complete failures, that he recommends pre ure in all cases to be applied to the wound itself whenever po ible. The limb should always be raised, and al) tight clothing, pariere, bandages and the like between the wound and the ly removed. A firm pad can always be improvised by oe a smooth Vey or cork in a clean handkerchief and folding it up. pad may then bo secured in ae i Arc eases ae like a site While = Pp pre ing may be controlled pre ure with that Bes. If pre ure on the wound itself fails to arrest hemorrhage, as happens at times, additional pre ure may be applicd—nearer to the heart than the wound for arteria) hamorrhage, and further from the heart for venous hemorrhage. Wounds in the palm are best treated by placing the pad in the closed fist, then binding up the fist firmly, and finally bending the elbow and securing the hand to the upper arm. When the wound is too extensive tc apply pre ure to it, and arterial hemorrhage is present, a tourniquet improvised as follows should be applied higher up the limb. A pad adel metabolite’ plies ovr’ tis iste: artery. and secured in position by a handkerchief folded into a scarf and firmly tied. The size of this pad should be about that of half [s. 366]
