Per-operative haemodynamic assessment of lower limb arterial surgery. Part 2: Modelling of the arterial system.
A simple lumped parameter model has been constructed to characterize the arterial system of the lower limb in man. It is found that such a simple model can represent the system and provide an excellent match with experimental blood flow and pressure data obtained during reconstructive arterial surgery. Based on the values of the model parameters, the model is able to predict the success and failure of surgery with the help of a discriminant function. The physical quantities of length and Young's Modulus of the model tube, however, are found to be outside the physiological range.
