Obviously, body size is important, and the ranges of normal values of cardiac output for 2-year-old children, 10-yearold children, and 50-year-old men are so different that they show only minimal overlap.

WebA pulse volume recording, or a PVR test, measures blood flow in your legs. It uses ultrasound (high-frequency sound waves) to evaluate circulation in your arteries. A PVR test is painless and noninvasive, so it doesn’t require any needles or cuts in your skin. It’s also called pulse volume plethysmography or a segmental pressure test.
