Abstract
A method of and apparatus for controlling the speed of a rotary blood pump, which comprises the measuring the speed and/or power of said pump, calculating an array of system parameters derived from the measured speed, analysing these parameters, and if the analysis indicates ventricular collapse or imminent ventricular collapse, then the speed of said pump is altered, to minimise the risk of the collapse occurring. Preferably the analysis is done using a Classification and Regression Tree (CART) analysis.
