Background. Shock is one of the causes of mortality in the intensive care unit (ICU). Traditionally, hemodynamics related to shock\nhave been monitored by broad-spectrum devices with treatment guided by many inaccurate variables to describe the\npathophysiological changes. Critical care ultrasound (CCUS) has been widely advocated as a preferred tool to monitor shock\npatients. The purpose of this study was to analyze and broaden current knowledge of the characteristics of ultrasonic\nhemodynamic pattern and investigate their relationship to outcome. Methods. This prospective study of shock patients in CCUS\nwas conducted in 181 adult patients between April 2016 and June 2017 in the Department of Intensive Care Unit of West China\nHospital. CCUS was performed within the initial 6 hours after shock patients were enrolled. The demographic and clinical\ncharacteristics, ultrasonic pattern of hemodynamics, and outcome were recorded. A stepwise bivariate logistic regression model\nwas established to identify the correlation between ultrasonic variables...................................
