  17. Doppler Stroke Volume Calculation • Assumption used for measuring SV using Doppler are: • Accurate cross-sectional flow area measurement. • Laminar Flow. • Spatial ‘flat’ flow velocity profile. • Parallel intercept angle between Doppler beam and • direction of blood flow. • 5. Velocity and diameter measurements are made at the • same anatomic site.

  18. Stroke Volume Calculation VTI cm/s
