A new type of fluorocarbon liquid oxygenator.

A new oxygenator based on gas transfer across liquid-liquid interfaces (liquid oxygenator) is introduced. Perfluorinated chemicals are used as gas carriers. This liquid oxygenator differs from others in its concept basing on the dispersion of the blood droplets in an inert liquid by means of shear forces. This method allows high efficiency both with respect to saturation and to required blood flow. The results of gas transfer experiments in vitro and in vivo are satisfactory.
