Description
In this study, electrical impedance plethysmograph was used to measure
the nonlinear elastic properties of the leg arteries. Two methods
were used. In method one, a pressure cuff was wrapped around the
lower leg and the recordings were made from under the cuff. Also a
second set of recordings were made at a site distal to the cuff, to
determine the attenuation of blood pressure pulse by the cuff at cuff
pressures above diastolic. In method 2 an Inverter was used and
recordings were made from the same segment. Also recordings were made
from the upper arm at the heart level to define the blood pressure
pulse, that causes the volume change in the leg arteries. A wide
range of pressures were used and V-P and compliance curves were
calculated with both the methods. In order to improve the accuracy
and reduce operator errors, a personal computer based data acquisition
and processing system was developed.
