Fluid responsiveness is defined as an increase in stroke volume by 10% to 15% after infusion of 500 ml crystalloid over 10 min to 15 min. The wide application of point‑of‑care ultrasound in the operating room makes it possible to evaluate fluid responsiveness by ultrasound. Transthoracic echocardiography (TTE) examination is noninvasive, while trans‑esophageal echocardiography (TEE) is minimally invasive. During the perioperative period, TEE can monitor fluid responsiveness in a dynamical, real‑time, and continuous manner, with stable quality of images. The review is to summarize the ultrasound indicators that can predict fluid responsiveness, including respiratory‑pulse parameters, respiratory variation of the vein, parameters related to cardiac diastole function, and fluid responsiveness tests, so as to provide comprehensive understanding.
