In the mock circulation are investigated methods for pressure measurement developed especially for the application on artificial ventricles. They require the in-vivo-confirmation in the long-term experiment. An exact analysis of the pressure curves gives information about the absolute measuring values and also about the function of the pump itself, such as about the points of reaching the final positions of the pump membrane. Via a control related to this in the "full stroke" mode with ejection of the complete stroke volume, when the stand-still times of the membrane are minimized, in addition to this the atrial pressures and the cardiac output can be determined. Eventual non-linearities in the lower pressure region (less than or equal to 0.5 kPa) are not essential in the measurement of the ventricular pressure with amplitudes of 20-25 kPa on the left side and are not investigated in detail.
在模拟循环中，研究了专门为人工心室应用开发的压力测量方法。这些方法需要在长期实验中进行体内验证。对压力曲线的精确分析可提供有关绝对测量值的信息，还可提供有关泵本身功能的信息，例如泵膜到达最终位置的点。通过在“全冲程”模式下进行与此相关的控制，在排出完整冲程容积时，当膜的静止时间最小化时，除了可以确定心房压力和心输出量外，还可以确定心室压力。在左侧幅度为20 - 25 kPa的心室压力测量中，低压区域（小于或等于0.5 kPa）的任何非线性都不重要，因此未进行详细研究。
