Directions for Locating and Injecting the Brachial Artery.
The course of the Brachial Artery is in a line drawn from the outer side
of the armpit to the center of the bend of the elbow, and along the
inner edge of the Biceps or largest muscle of the upper part of the arm
(see illustration). This artery will be found just at the inner edge of
the Biceps, at a point midway between the elbow and shoulder—sometimes a
little under the edge of the muscle in very muscular subjects. Hold the
arm out from the side of the body, twisting it a little outwards, and
make the incision at the edge of the muscle. By reference to the plate
illustrating the location of this artery, you will see the point marked
for the incision. Having taken up the artery, make the slit and secure
the syringe in it, the point directed towards the shoulder, and proceed
according to the general directions already given for the Carotid Artery
injection.
