The effect of a pumpless arteriovenous bypass with a microporous membrane oxygenator (MO) on the cardiopulmonary dynamics of dogs revealed an increase in cardiac output and cardiac work proportional to the increase in extracorporeal blood flow. Several current MOs offer so little resistance to blood flow that shunt flows exceeding a third of the normal cardiac output can easily be obtained. This should be enough for CO2 extraction covering metabolic production, and would add a non negligible amount of O2 to the blood.
采用微孔膜氧合器（MO）的无泵动静脉旁路对犬心肺动力学的影响显示，心输出量和心脏作功的增加与体外血流量的增加成正比。目前的几种微孔膜氧合器对血流的阻力很小，以至于很容易获得超过正常心输出量三分之一的分流流量。这足以满足覆盖代谢产生的二氧化碳的摄取，并会给血液中增加不可忽略量的氧气。
