体外循环tǐwài xúnhuán应用特殊机械装置把血液从身体内引到体外处理后再送回体内,如心肺体外循环是把静脉血引到体外,用人工肺脏使成为动脉血,再用人工心脏送回体内动脉,从而使全身血液暂时改道,不经过心肺。{extracorporeal circulation; blood circulation by using a special mechanical device to draw the blood from inside the body for extracorporeal treatment and then infuse it back into the body. For example, extracorporeal cardiopulmonary circulation means drawing the venous blood from the body, using artificial lungs to turn it into arterial blood, and then using an artificial heart to pump it back into the artery so that the blood flows through a make-shift course instead of the heart and lungs.} |
