5 Positioning the calipers, measure the
ventricular length. (See "Working with
calipers" on page 47.)
6 Save the calculation.
To measure peak velocity
For each cardiac measurement, the system saves
up to five individual measurements and
calculates their average. If you take more than
five measurements, the most recent measurement
replaces the fifth one. If you delete a saved
measurement from the patient report, the next
measurement taken replaces the deleted one in
the patient report. The most recently saved
measurement appears at the bottom of the
calculations menu.
1 On a frozen Doppler spectral trace, press the
key.
CALCS
2 From the calculations menu, select MV, TV,
TDI, or P. Vein.
3 Do the following for each measurement you
want to take:
a Select the measurement name from the
calculations menu.
b Position the calipers. (See "Working with
calipers" on page 47.)
c Save the calculation. (See "To save a
calculation" on page 51.)
To calculate Velocity Time Integral (VTI)
Note: This calculation computes other results in
addition to VTI. See the table "Cardiac Calculations"
on page 57.
1 On a frozen Doppler spectral trace, press the
key.
CALCS
2 From the calculations menu, select VTI under
MV, AV, TV, PV, or LVOT.
3 Position the caliper at the start of the
waveform, and press the
the trace.

SELECT
4 Using the touchpad, trace the waveform.
To make a correction, select Undo on‐screen,
backtrack with the touchpad, or press the
key.
BACKSPACE
5 Press the key to complete the trace.
SET
Save the calculation. (See "To save a
6
calculation" on page 51.)
For information on the automatic trace tool, see
"To trace automatically (Doppler)" on page 50.
To calculate Right Ventricular Systolic
Pressure (RVSP)
1 On a frozen Doppler spectral trace, press the
key.
CALCS
2 From the calculations menu, select TV and
then select TRmax.
3 Position the caliper. (See "Working with
calipers" on page 47.)
4 Save the calculation. (See "To save a
calculation" on page 51.)
To adjust the RA pressure, see "To delete a
5
vascular or cardiac measurement" on page 77.
Changing the RA pressure from the default 5
affects the RVSP calculation in the patient
report.
To calculate Pressure Half Time (PHT) in MV,
AI, or TV
1 On a frozen Doppler spectral trace, press the
key.
CALCS
2 From the calculations menu, select MV, AV, or
TV, and then select PHT.
3 Position the first caliper at the peak, and press
the key.
SELECT
A second caliper appears.
4 Position the second caliper:
• In MV, position the caliper along the EF
slope.
