Introduction to VExUS
Fundamentally, the Venous Excess Ultrasound (VExUS) protocol uses Doppler ultrasound to measure the speed and direction of blood flow thorough the veins, giving medical providers valuable information about the pressure and degree of congestion within the venous circulation.
The initial VExUS study was published in 2020 by Beaubien-Souligny et al, and demonstrated that a novel, 4-point ultrasound protocol could accurately predict the the incidence of cardiorenal acute kidney injury after heart surgery. Since that time, over 175 peer-reviewed articles have validated and investigated the technique, opening opportunities for innovations and novel applications of Doppler ultrasound for dynamic bedside measures of volume assessment.
