Abstract:
Venous congestion is an important pathophysiological mechanism impacting organ function in critically ill patients. However, congestion physiology is complex, can affect multiple organ systems, and is subject to change rapidly over time. Contemporary multimodal assessment integrates both traditional approaches and emerging technologies to refine our understanding and improve clinical evaluation of this dynamic process. In this review, we explore how combining various ultrasound assessments can enhance the evaluation of congestion in critically ill patients. Topics include diastolic function evaluation with echocardiography, the Venous Excess Ultrasound (VExUS) assessment, and lung ultrasound.

Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
