Figure 10–31. Cardiac Calculation Sub-Menu
Select MEAN PG from the Calculation Sub-Menu. Perform the
measurement described on
7–15. Set the first cursor on the
waveform trace starting point.
If Trace Auto is selected, the waveform is automatically traced
after the second cursor is fixed.
If Trace Auto is not selected, manually trace the desired portion
of the waveform.
Press Set to complete the the Mean PG measurement.
Automatic Calculation of Mean PG
If velocity was previously measured and calculated in Doppler
Mode, Mean PG is calculated from the velocity value when
Mean PG is first selected in the Calculation Sub-Menu.
The waveform is automatically traced. Velocity and Mean PG
are also displayed on the screen.
