Noninvasive flowmetry in vascular surgery: Use of a noninvasive electromagentic flowmeter

Using anin vitro model, the measurements made using a noninvasive electromagnetic flowmeter have been validated using standard square wave electromagnetic flowmetry. Clinically, the noninvasive electromagnetic flowmeter provides information as to the functional significance of vascular occlusive disease that is not available through other techniques, gives an accurate, quantitative measurement of the peak pulsatile blood flow through a limb, thus providing an index of tissue perfusion and therefore, the degree of involvement of the disease in the peripheral, vascular system. Presented at the Post-congress Meeting on Noninvasive Flowmetry in Angiology, of the 21st Congress of the Japanese College of Angiology, Fukuoka, Japan, October 30–November 1, 1980.
