Abstract We are developing an implantable blood flow and pressure monitor for pulmonary hypertension. Implantable hacmodynnmic monitors have been used to continuously measure pulmonary pressures in humans in a research setting. However there is currently no implantable haemodynamic monitoring device available that measures both blood pressure and flow. We aim to measure blood flaw using the impedance technique from a catheter through the right ventricle. Initial experiments have been conducted in saline and blood to validate our experimenrnl rechnique. Excellenr agreement was found between theory and experimelttal results. A numerical model of rhe chest is being developed tu develop un algorithm that calculates blood flow from impedance measurements. At a later stage we hope to use sheep to demonstrate the usefullness of the developed device.
