32 Measurements and calculations
b Use the automatic trace tool to trace the waveform. See “To perform automatic trace
measurements in Doppler” on page 18.
c Tap Save Calc to save the calculation.
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 form. The BSA is calculated automatically.
2 Measure from LVOT (2D):
a On a frozen 2D image, tap Calcs .
b On the calculations menu, tap Ao/LA then LVOT D .
c Position the calipers.
d Tap Save Calc to save the calculation.
3 Measure from
LVOT
(Doppler). Refer to “To calculate Velocity Time Integral (VTI)” on page 29. On
the calculations menu, tap
AV
and then
LVOT VTI
.
To calculate Cardiac Output (CO) or Cardiac Index (CI)
The CO and CI calculations require Stroke Volume (SV) and Heart Rate (HR) calculations. CI also requires
Body Surface Area (BSA). After the measurements are saved, the result appears in the patient report.
1 (CI Only) Fill in the Height and Weight fields on the patient form. The BSA is calculated automatically.
2 Calculate SV as described in “To calculate Stroke Volume (SV) or Stroke Index (SI)” on page 32.
3 Calculate HR as described in “To measure heart rate in Doppler” on page 27.
