Doppler ultrasonography has evolved into a cornerstone of ultrasound imaging. In this article, we delve into the fundamental principles of Doppler ultrasonography, introduce color and spectral Doppler analysis, and highlight common applications relevant to point-of-care (POCUS) practitioners. From enhancing the safety of bedside procedures to estimating cardiac output, to exploring findings of venous congestion, we review the key advantages, disadvantages, and challenges of using Doppler in POCUS.
多普勒超声已发展成为超声成像的基石。在本文中，我们深入探讨了多普勒超声的基本原理，介绍了彩色和频谱多普勒分析，并重点介绍了与即时护理超声（POCUS）从业者相关的常见应用。从增强床边操作的安全性、估计心输出量到探索静脉淤血的发现，我们回顾了在 POCUS 中使用多普勒的关键优势、劣势和挑战。
