Abstract
The instant invention relates to an improved process for oxygenating blood comprising: contacting said blood with oxygen-containing bubbles, said bubbles being coated with a liquid membrane, said liquid membrane phase permitting the permeation of oxygen into the blood whereby at least a portion of said oxygen passes through said membrane and into said blood; removing said liquid membrane coated bubbles as a three phase foam comprising gas bubbles coated with said liquid membrane suspended in blood; and coalescing said foam comprising gas bubbbles to form three separate bulk phases comprising the liquid membrane phase, a gaseous phase and a blood phase, wherein the improvement comprises a liquid membrane phase comprising a biologically non-retainable liquid halocarbon compound. These liquid membrane formulations having a membrane phase comprising a biologically non-retainable liquid halocarbon compound exhibit improved coalescing characteristics.
