The clinician who uses cardio-pulmonary exercise testing (CPX) systems relies on the technical informations from the device producers. In this paper, the practicability, the accuracy and the safety of four different, available CPX systems are compared in the clinical area, using clinically orientated criteria. The exercise tests were performed in healthy subjects, in patients with cardiac and/or pulmonary disease as well as in young or old people. The comparison study showed, that there were partially large differences in device design and measurement accuracy. Furthermore, our investigation demonstrated that beneath repetitive calibrations of the CPX systems a frequent validation of the devices by means of a metabolic simulator is necessary. Problems in calibration can be caused by an inadequate performance or by unclean calibration gases. Problems in validation can be due to incompatibility of the CPX device and the validator. The comparison study of the four different systems showed that in the future standards for CPX testing should be defined.
使用心肺运动测试（CPX）系统的临床医生依赖于设备生产商提供的技术信息。本文采用以临床为导向的标准，在临床领域对四种不同的现有CPX系统的实用性、准确性和安全性进行了比较。运动测试在健康受试者、患有心脏和/或肺部疾病的患者以及年轻人或老年人中进行。比较研究表明，设备设计和测量准确性方面存在部分较大差异。此外，我们的调查表明，除了对CPX系统进行重复校准外，还需要通过代谢模拟器对设备进行频繁验证。校准问题可能由性能不足或校准气体不纯净引起。验证问题可能是由于CPX设备与验证器不兼容。对这四种不同系统的比较研究表明，未来应定义CPX测试的标准。
