Hemodynamic Changes in the Small Vessels in Man as Analyzed By Digital Plethysmography

Robert L. Johnson, Edward D. Freis, Harold W. Schnaper

Abstract

Plethysmography is the measurement of variations in the size of an organ or body part on the basis of the amount of blood passing through or present in the part. The development of new instruments, such as the digital plethysmograph, allowed for the better evaluation of specific antihypertensive therapies.
