 Operating Procedures
1. Select [Bullet] in the measurement menu.
In apical long-axis view, measure the following parameters:
At end diastole: LVLd apical
At end systole: LVLs apical.
2. In short-axis view at mitral valve level, ，measure the following parameters:
At end diastole: LVAd sax MV, the EDV is calculated
At end systole: LVAs sax MV, the ESV is calculated
The system calculates SV and EF; If height and weight have been input already, SI, EDV
Index and ESV Index are calculated.
3. Using touch screen knob to select HR source: ECG or input.
The CO and CI are calculated automatically.
