Abstract
Blood pressure is one of the vital signs and its accurate estimation using indirect methods of measurement is a challenge. Arterial pressure could not be estimated directly by inflatable cuffs (constructed from woven and non-woven fabrics) however those could be predicted using simulation modelling. In this investigation, three cuffs constructed from different fabrics were selected and simulation models were developed in Abaqus mimicking the phenomena of indirect blood pressure measurement. An anthropometric upper arm model was developed to validate the simulation models. The models showed good agreement with experimental results. Outcome of this study showed that it was possible to visualize pressure distribution through simulation models and to predict pressure transmission from cuff to arm and then to the artery by calculating pressure transmission ratio. This study also found that the prediction of the arterial pressure through simulation may help in identifying errors associated with current method of indirect blood pressure measurement which may help in designing of new cuffs using suitable constructing materials for accurate estimation of blood pressure.
