Abstract

Instead of direct measurement of pressure head and flow rate of a centrifugal blood pump, the authors previously proposed a method of estimating these measurements. In this study, to ascertain the adequacy of the proposed method, an acute animal experiment was carried out using an adult goat equipped with a TAH consisting of two centrifugal pumps. The results indicated that the ARX model identified even in a mock circulation could estimate flow rate in the recipient accurately enough, although estimation accuracy of pressure head was not high.
