Acquire an apical four-chamber view to measure the EDV (A4C) and ESV (A4C).
3. Press Freeze.
4. Press <Calc> key to enter measurement mode and select Auto EF or press the
programmable key assigned to Auto EF.
5. System will pause and then display traces on the ED and ES frames.
a) OLEDs are available to toggle between Systolic and Diastolic Frame by pressing the
OLED. Turn the dial to adjust the frame to be used for calculation.
b) Traces can be modified by pointing to the segment of trace to be adjusted. Caliper
points will become highlighted at which time the trackball can be used to drag the trace
to the desired position.
6. When data is acceptable, press ACCEPT OLED and data will be stored to the report.
7. If the height and weight have already been entered, the SV, EF, SI, EDV Index and ESV
Index are calculated. ECG obtains the HR automatically. If ECG is not connected, HR can
