Significant reduction in minute ventilation and peak inspiratory pressures with arteriovenous CO sub 2 removal during severe respiratory failure

Abstract

Extracorporeal CO2 removal using a low-resistance gas exchanger in a simple arteriovenous shunt allows significant reduction in minute ventilation and peak inspiratory pressure without hypercapnia or the complex circuitry and monitoring required for conventional extracorporeal membrane oxygenation. Arteriovenous CO2 removal can be applied as an easy and cost-effective treatment to minimize ventilator-induced barotrauma and volutrauma during severe respiratory failure.
