Meaning of Impedance Plethysmography

Abstract

IMPEDANCE plethysmography is a method of measuring the resistive impedance of a limb segment. Nyboer1 pointed out that the resistive impedance variation ΔR during the heart cycle is proportional to the blood volume ΔV transiently stored in the segment where ρ is the blood resistivity, l the length of the segment and R0 the mean steady value of the segment resistance. Nyboer1 proposed a method of calculating the blood flow by extrapolating the post-systolic slope of the plethysmogram. This procedure is subject to some criticisms and may lead to wrong results.
