Isolated organ perfusion systems preserve the viability of the organ of interest by pumping blood or other oxygenated fluid through the main vessels. Models are maintained at a constant mean pressure or a constant mean flow. Inclusion of an Inline flow sensor into the tubing circuit allows for confirmation of the pump flow rate, ensuring proper perfusion to the organ. Transonic® flow sensors can be calibrated for blood, buffer solutions and other non-aerated liquids used in perfusion studies.

In a working heart model Pressure-Volume Catheters can be place in the ventricle of the isolated heart to measure contractility parameters.
