2 In Doppler, measure LVOT Vmax, and then measure AV Vmax. See
From the calculations menu, select AV, select sample site, and then select Vmax.:
Note
To calculate Qp/Qs
The Qp/Qs calculation requires two measurements in 2D and two measurements in Doppler. After the
measurements are saved, the result appears in the patient report.
1 On a frozen 2D image, press the CALCS key.
2 Do the following to measure from LVOT D and again to measure from RVOT D:
a From the calculations menu, locate Qp/Qs and then select LVOT D or RVOT D.
b Position the calipers.
c Save the calculation as described in
3 On a frozen Doppler spectral trace, press the CALCS key.
4 Do the following to measure from LVOT VTI and again to measure from RVOT VTI:
a From the calculations menu, select Qp/Qs and then select LVOT VTI or RVOT VTI.
b Press the SELECT key to start the trace.
c Using the touchpad, trace the waveform.
To make a correction, select Undo on-screen, backtrack with the touchpad, or press the backspace key.
d Press the SET key to complete the trace.
e Save the calculation as described in
For information on the automatic trace tool, refer to
To calculate Stroke Volume (SV) or Stroke Index (SI)
The SV and SI calculations require a measurement in 2D and a measurement in Doppler. SI also requires Body
Surface Area (BSA). After the measurements are saved, the result appears in the patient report.
1 (SI Only) Fill in the Height and Weight fields on the patient information form. The BSA is calculated
automatically. Refer to
2 Measure from LVOT (2D):

Vmax can also be determined from the VTI measurement. See
Time Integral (VTI)" on page 89. From the calculations menu, select AV, select
sample site, and then select VTI.
