Point-of-care ultrasonography in cirrhosis-related acute kidney injury: How I do it

Figure 5 Stroke volume is the product of the cross-sectional area of left ventricular outflow tract in cm² and velocity time integral in cm. Left ventricular outflow tract (LVOT) area is derived from the LVOT diameter in zoomed parasternal view using the formula πr² assuming it to be a circle, and LVOT velocity time integral is obtained by tracing the envelope of the pulsed wave Doppler spectrum of systolic flow in the apical 5-chamber view. LVOT: Left ventricular outflow tract; VTI: Velocity time integral. Citation: Argaiz ER, Romero-Gonzalez G, Rola P, Spiegel R, Haycock KH, Koratala A.
