To calculate Velocity Time Integral (VTI)
Note
1 On a frozen Doppler spectral trace, press the CALCS key.
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 SELECT key to start the trace.
4 Using the touchpad, trace the waveform.
a To make a correction, select Undo on-screen, backtrack with the touchpad, or press the backspace key.
5 Press the SET key to complete the trace.
6 Save the calculation as described in
For information on the automatic trace tool, see
To calculate Right Ventricular Systolic Pressure (RVSP)
1 On a frozen Doppler spectral trace, press the CALCS key.
2 From the calculations menu, select TV and then select TRmax.
3 Position the caliper. (Refer to "Working with calipers" on page 1.)
4 Save the calculation as described in
To adjust the RA pressure, refer to
Note
To calculate Pressure Half Time (PHT) in MV, AI, or TV
1 On a frozen Doppler spectral trace, press the CALCS key.
2 From the calculations menu, select MV, AV, or TV, and then select PHT.
Position the first caliper at the peak, and press the SELECT key. A second caliper appears.
3 Position the second caliper:
In MV, position the caliper along the EF slope.
