PURPOSE: Carotid blood flow ultrasonography has been increasingly used to assess the intravascular volume status in critically ill patients. Measurements of carotid blood flow with passive leg raise or after a fluid challenge is gaining importance in caring for patients in emergency rooms and intensive care units. A study of sonographers by Tanuguchi et al reported reasonable agreement in measuring carotid blood flow in healthy volunteers, but there are no studies looking at agreement in patients with shock. Also, there are no studies describing variability in physicians performing these carotid measurements. Considering the importance of carotid ultrasound in hemodynamic assessment, this study is conducted to examine the intra-observer and inter-observer variability in physicians measuring carotid blood flow in patients with shock.
