Abstract

The possibility of controlling an artificial heart by the arteriovenous oxygen difference is discussed by means of the model simulation of the human organism. The simulation results are compared with these of the control by the Starling mechanism. No improvement of the results was obtainable because the behaviour of the arteriovenous oxygen difference is very dependent on the kind and the ascent of the load. The control of the artificial heart by the Starling mechanism appeared more favourable also on changed conditions in the atrium.

摘要

通过人体模型模拟，探讨了利用动静脉氧差控制人工心脏的可能性。将模拟结果与通过斯塔林机制进行控制的结果进行了比较。由于动静脉氧差的行为非常依赖于负荷的类型和增加幅度，因此无法获得结果的改善。在心房条件改变的情况下，通过斯塔林机制控制人工心脏似乎更有利。
