An Automatically Regulated Low Prime Heart-Lung Machine for Infants: A Rabbit Model

A new compact heart-lung machine for paediatric use was designed. The total volume of this system of only 90ml allows for priming without the use of donor blood. The priming volume could be kept small mainly by replacing gravity drainage with drainage by a negative pressure in the venous reservoir....

Description
Summary:A new compact heart-lung machine for paediatric use was designed. The total volume of this system of only 90ml allows for priming without the use of donor blood. The priming volume could be kept small mainly by replacing gravity drainage with drainage by a negative pressure in the venous reservoir. To avoid volume shifts between the extracorporeal circuit and the infant's circulation and to safely operate this minimal volume circuit, the heart-lung machine was automatically controlled. In this study we show that the miniaturized system functioned reliably under various conditions during cardiopulmonary bypass in rabbits.
