Measurements and calculations 5-29
b In the measurements list, tap Min D .
c Measure the diameter with the calipers.
d To save the measurements, tap under the measurement name.
To measure deceleration time (Decel)
1 On a frozen Doppler spectral trace, tap Calcs .
If this control is hidden, tapping More Controls displays it.
2 On the MV/MR calculation list, tap Decel .
A caliper appears.
3 Drag the active caliper to the first point.
4 Drag the other caliper to the second point.
5 To save the measurements, tap under the measurement name.
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 oldest
measurement. If you delete a saved measurement from the patient report, the next measurement taken
replaces the deleted one in the patient report.
1 On a frozen Doppler spectral trace, tap Calcs .
If this control is hidden, tapping More Controls displays it.
2 For each calculation you want to perform, on the calculation list, choose MV/MR , TV/TR , TDI , or P Vein ,
and then do the following:
a Tap the measurement name.
b Position the calipers.
To make a correction, trace backward on the dotted line.
In some measurements, you can click Next to change to the next measurement.
c Save the calculation: tap .
To calculate Velocity Time Integral (VTI)
This calculation computes other results in addition to VTI including VMax, PGMax, VMean, and PGMean.
1 On a frozen Doppler spectral trace, tap Calcs .
If this control is hidden, tapping More Controls displays it.
