尽管旋转式血泵不包含用于适应生理流动需要的固有机构，但迄今为止仅进行了一些努力来获得稳健的监测和控制方法。本文论述了对此类泵进行无创监测的必要性以及传感器的选择和研制要点。本文讨论了一种利用流入插管周围心房壁塌陷所获得的数据监测心房压力的策略，以及该方法在动物试验和计算机模拟中的初步结果。如果满足一些基本标准，这种方法可能会导致可靠和需求响应控制器。
Although rotary blood pumps do not contain an inherent mechanism for adaptation to physiological flow necessities, hitherto only a few efforts have been made to obtain robust monitoring and control methods. This paper discusses the necessity of noninvasive monitoring of such pumps and the crucial points of sensor selection and development. A strategy of monitoring atrial pressure out of the data obtained by the collapse of the atrial wall around the inflow cannula and initial results on animal tests and computer simulation of this method are discussed. This approach might lead to reliable and demand-responsive controllers, if some basic criteria are fulfilled.
