The aim of the work is focused on the generation of FEM model by Ansys code, able to effectively evaluate the miscuffing errors. For this purpose it was measured the circumferential distribution of the pressure produced by the cuff on the arm during the inflation and deflation phases, concerning bladders of longitudinal dimensions comprised between 60% and 100% of the circumference of the experimental arm. The model parameters have been identified by searching vessel-occluded conditions at the subject systolic blood pressure for the bladder/arm ratio equal to 80%. The Young’s modulus is fixed to 40 kPa and the Poisson’s ratio to 0,44. The measured pressure distributions for the 60%, 70%, 90% and 100% ratios have allowed to verify miscuffing errors reported in bibliography by the constructed FEM model.

Abstract
The aim of the work is focused on the generation of FEM model by Ansys code, able to effectively evaluate the miscuffing errors. For this purpose it was measured the circumferential distribution of the pressure produced by the cuff on the arm during the inflation and deflation phases, concerning bladders of longitudinal dimensions comprised between 60% and 100% of the circumference of the experimental arm. The model parameters have been identified by searching vessel-occluded conditions at the subject systolic blood pressure for the bladder/arm ratio equal to 80%. The Young’s modulus is fixed to 40 kPa and the Poisson’s ratio to 0,44. The measured pressure distributions for the 60%, 70%, 90% and 100% ratios have allowed to verify miscuffing errors reported in bibliography by the constructed FEM model.
