About

Passive leg raise (PLR) and fluid challenge are useful tools in assessing the fluid responsiveness. However, they require continuous monitoring of cardiac output, which is usually an invasive technique and in some cases not always available. Vascular ultrasound can be an alternative to cardiac output monitoring in a fluid status evaluation. The common carotid artery (CCA) is an easily accessible vessel. It has recently been noted that the diameter of this artery changes after an intravenous fluid bolus. It is possible that the change in the diameter of the common carotid artery during passive leg raise and fluid challenge can be a predictor of fluid responsiveness.
