1 In 2D:
a On a frozen 2D image, tap Calcs .
b On the calculations menu, tap Ao/LA .
c From the Ao/LA calculation list, select LVOT D .
d Position the calipers.
e Tap Save Calc to save the calculation.
2 In PW Doppler, measure either LVOT Vmax or LVOT VTI.

Vmax - Tap AV , then tap the Vmax measurement under LVOT . Position the caliper, and then save the
measurement.

VTI - Tap AV , then tap the VTI measurement under LVOT . Use the automatic trace tool to trace the
waveform, and then save the measurement.
3 In CW Doppler, measure either AV Vmax or AV VTI.

Vmax - Tap AV , and then Vmax . Position the caliper, and then save the measurement.

VTI - Tap AV and then VTI . Use the automatic trace tool to trace the waveform, and then save the
measurement.
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, tap Calcs .
2 Do the following to measure from LVOT D and again to measure from RVOT D:
a From the Qp/Qs calculations list, select LVOT D or RVOT D .
b Position the calipers.
c Tap Save Calc to save the calculation.
3 On a frozen Doppler spectral trace, tap Calcs .
4 Do the following to measure from LVOT VTI and again to measure from RVOT VTI:
a On the calculations menu, tap Qp/Qs and then LVOT VTI or RVOT VTI .
Notes
If VTI is chosen, the Vmax value derived from the trace is used as input to the
AVA calculation.
Notes

If VTI is chosen, the Vmax value derived from the trace is used as input to the
AVA calculation.

If VTI measurements are made for both LVOT and AV, a second AVA result is
provided.
