Simulation Models Predicting Pressure Distribution and Transmission Underneath Blood Pressure Cuffs of Different Types

Abstract

Inflatable cuffs of different types are used for the measurement of blood pressure using the indirect method. It is crucial to find pressure distribution and transmission underneath different types of blood pressure measurement cuffs for estimating accurate values of blood pressure. In this study, three simulation models are developed mimicking blood pressure measurement through three cuffs constructed using fabrics that have dissimilar geometric and mechanical properties. Finite element analysis (FEA) is carried out to predict pressure distribution and transmission underneath these cuffs. For validation of these models, an arm simulator was developed. The models provide good agreement with the experimental results. The pressure distribution at the interface of the selected cuffs and arm is not identical.
