A noninvasive method of measuring cardiac output is described. The method uses adaptive aorta models in conjunction with femoral and carotid pulse contour waveform measurements to calculate aortic flow. Results are presented from measurements on dogs using internal pressure recordings made with fluid-filled catheters and compared with electromagnetic flow measurements taken in the ascending aorta. Preliminary results using external pulse measurements on patients are also presented and compared with thermal dilution measurements.
本文描述了一种测量心输出量的非侵入性方法。该方法将自适应主动脉模型与股动脉和颈动脉脉搏轮廓波形测量相结合来计算主动脉血流量。文中给出了对狗的测量结果，这些测量使用了充液导管进行的内部压力记录，并与升主动脉处的电磁血流量测量结果进行了比较。还给出了对患者进行外部脉搏测量的初步结果，并与热稀释测量结果进行了比较。
