Cardiac output (CO), along with blood pressure and vascular resistance, is one of the most important parameters of maternal hemodynamic function. Substantial changes in CO occur in normal pregnancy and in most obstetric complications. With the development of several non-invasive techniques for the measurement of CO, there is a growing interest in the determination of this parameter in pregnancy. These techniques were initially developed for use in critical-care settings and were subsequently adopted in obstetrics, often without appropriate validation for use in pregnancy. In this article, methods and devices for the measurement of CO are described and compared, and recommendations are formulated for their use in pregnancy, with the aim of standardizing the assessment of CO and peripheral vascular resistance in clinical practice and research studies on maternal hemodynamics.

心输出量（CO）与血压和血管阻力一起，是产妇血液动力学功能最重要的参数之一。CO 在正常妊娠和大多数产科并发症中会发生显著变化。随着 CO 测量的几种非侵入性技术的发展，人们对妊娠中这一参数的测定越来越感兴趣。这些技术最初是为在重症监护环境中使用而开发的，随后在产科中采用，通常没有经过适当的验证即可用于妊娠。本文描述并比较了 CO 的测量方法和设备，并就其在妊娠中的应用提出了建议，目的是在临床实践和产妇血液动力学研究中标准化 CO 和外周血管阻力的评估。版权所有 © 2019 ISUOG。由 John Wiley & Sons Ltd 出版。
