Stroke Volume & Cardiac Output Measurement on POCUS Accurately measure LVOT diameter: 1. Obtain PLAX 2. Zoom to LVOT 3. Measure at mid systole, 1cm from aortic valve apparatus Calculate VTI: 1. Obtain A5c view 2. Place PW doppler into LVOT 3. Run PWD trace 4. Trace around PWD trace CO = HR x LVOT VTI x π (LVOT Diam/2) 2 SV = LVOT VTI x π (LVOT Diam/2) 2 - Dr. Jonny Wilkinson @Wilkinsonjonny #Stroke #Volume #Cardiac #Output #Measurement #POCUS #cardiology
