In a clinical study of oesophageal manometry with fluid-filled catheters, both a non-perfused system and a perfused system with a syringe pump have been compared to a system with a low-compliance perfusion pump, which served as a reference. Significantly lower values of motility amplitudes, motility derivatives, and partly of LES pressures, and a time delay of up to 0.5 sec of the amplitude maximum were obtained with the non-perfused system and the system with a syringe pump in comparison to the low-compliance system. Since the oesophageal function can be erroneously evaluated by use of a non-perfused system or a perfused system with a syringe pump, such systems cannot be recommended for clinical use.
在一项使用充液导管进行食管测压的临床研究中，将非灌注系统和带有注射泵的灌注系统与作为参考的低顺应性灌注泵系统进行了比较。与低顺应性系统相比，非灌注系统和带有注射泵的系统获得的运动幅度、运动导数以及部分LES压力的值显著更低，并且幅度最大值出现了长达0.5秒的时间延迟。由于使用非灌注系统或带有注射泵的灌注系统可能会错误地评估食管功能，因此不建议将此类系统用于临床。
