First paragraph (this article has no abstract)

Livigni and coworkers [1] reported on the safety and efficacy of a venovenous carbon dioxide removal (VVCO2R) circuit in a short-term study (to 12 hours) conducted in healthy sheep. During extracorporeal carbon dioxide removal, carbon dioxide is transferred across a gas exchanger whereas oxygen diffuses across the native lungs.
