Volume-Pressure Curves of the Human Arm
After interruption of the circulation, pressure changes in the brachial artery and a forearm vein were recorded and plotted against volume of blood injected intra-arterially expressed in ml./100 cc. of arm tissue. The resulting volume-pressure curves showed a steep rise with the first injection, a linear rise in the center section and a rapid increase during the last injection. These curves were not influenced by either sex, age or moderate systemic hypertension.
