The proper siting of cannulas to return oxygenated blood to patients on long-term membrane oxygenator support is as yet undecided. This experimental study on adult sheep shows the problems of obtaining perfusion of the coronary arterial tree when blood is returned to the ascending aorta. Our 11 experiments demonstrate that the coronary arterial tree is perfused with blood ejected from the left ventricle except during very high bypass flows (85% bypass) or when the aortic valve is rendered incompetent.
在长期使用膜式氧合器支持的情况下，将套管正确放置以向患者回输氧合血的问题尚未确定。这项针对成年绵羊的实验研究表明，当血液回输至升主动脉时，在灌注冠状动脉树方面存在问题。我们的11项实验表明，除了在极高的体外循环流量（85%体外循环）或主动脉瓣功能不全时，冠状动脉树由左心室射出的血液灌注。
