These data presented here demonstrate how careful analysis of mock loop testing can lead to useful measurements for long-term calf experiments. The accuracy of the data rae primarily dependent upon a valid circulatory system analog and good experimental technique. These methods of determining arterial pressure, left atrial pressure and cardiac output have allowed us to obtain recordds of these important parameters for periods as long as 100 days in calves with total artificial heart implantation. These methods have also enabled us to automatically control the artifical heart under conditions of rest, exercise and pharmacologic treatment with the use of only one external pneumatic drive line pressure transducer.
此处呈现的数据表明，对模拟环路测试进行仔细分析如何能够为长期的小牛实验带来有用的测量结果。数据的准确性主要取决于有效的循环系统模拟和良好的实验技术。这些测定动脉压、左心房压和心输出量的方法，使我们能够在植入全人工心脏的小牛身上，长达100天的时间里获取这些重要参数的记录。这些方法还使我们能够仅使用一个外部气动驱动管路压力传感器，在休息、运动和药物治疗条件下自动控制人工心脏。
