Abstract
Data of pressure and flow of an arterial bed can be obtained from physiologic perfusion or from artificial perfusion using a pump. Perfusion is usually carried out with a pump either under pressure control (pressure source) or under flow control (flow source). An advantage of pressure perfusion is that the intraluminal pressure is set at physiological levels while during flow perfusion the pressure may rise above the physiological range. Flow perfusion is often easier to realize and the measured pressure is a direct reflection of peripheral resistance. Peripheral resistance is mean pressure divided by mean flow; it is the slope of the line that connects a point of the mean pressure-mean flow curve with the origin.
