Abstract: Critical Care Ultrasound(CCUS)is the one of the ultrasound technologies which integrates the bedside ultrasound application into daily clinical practice in critical care medicine. It has multiple roles, at first is a non-invasive monitoring tool to measure variables that can reflect the essence of the disease, and then is a comprehensive visualized tool to evaluate the pathophysiological status and structural changes of organs, which facilitates the critical care providers to know more about the patients and provides more reliable evidence to promote the accuracy and efficiency of the diagnosis, the clinical decision-making and the treatment of the critically ill. Therefore, the critical care ultrasound has been used as one of the core technologies of critical care. The characteristics and advantages of CCUS destine it as an orientation and instruction of visualized diagnosis and treatment. We devote ourselves to explore methods of integrating the application of CCUS into clinical management of critically ill, and establish specific approaches and workflows to standardize the clinical practice of clinicians and reduce medical errors. Therefore, a new diagnostic and treatment pattern can be developed, which is called visualized critical care. It is a care pattern of critical illness based on the CCUS visualization evidence including the pathophysiological status and other informations. This article will carefully discuss the connotation of CCUS, the unique clinical value in critically ill patients, and the value of visualized critical care approaches in acute respiratory and circulatory collapse and shock management, etc..
