Twenty-four patients undergoing cardiopulmonary bypass have been studied and the work of respiration was measured (1) before the incision, (2) before bypass with the thorax open, (3) after bypass, and (4) after suturing of the incision. Our results indicate that moving the thoracic wall requires 10 to 14% of the respiratory work and that little change occurs as a consequence of cardiopulmonary bypass.
对24例接受体外循环的患者进行了研究,并测量了呼吸功:(1) 切口前;(2) 胸部打开后体外循环前;(3) 体外循环后;(4) 切口缝合后。我们的结果表明,胸廓运动需要10%至14%的呼吸功,并且体外循环后变化不大。
