13.4.2 Single plane ellipse measurement LV function
Measurement method:
1. Move the cursor to
〖
LV
〗
menu item, pop up its submenu. Move the cursor to
〖
S-P Ellipse
〗
submenu,
press
『
Set
』
key , the cursor will show “+”.
2. At end systole of LV, measure the parameters as below can get ESV value:
LVLs: the measurement method is the same as “Distance” measurement of B general measurement;
LVALs: the measurement method is the same as “Ellipse” area measurement of B general
measurement.
3. At end diastole of LV, measure the parameters as below can get EDV value:
LVLd: the measurement method is the same as “Distance” measurement of B general measurement;
LVALd: the measurement method is the same as “Ellipse” area measurement” of B general
measurement.
4. The parameters of SV and EF will be calculated and displayed at the same time after LVALd
measurement.
13.4.3 Other measurement methods of LV function
The detailed operation of measurement (double plane ellipse, bullet volumetric and modified Simpson)
is the same as single plane ellipse. It can refer to the corresponding measurement methods of B general
measurement.
13.4.4 Internal diameter of Right Ventricle (RV)
1. Move the cursor to
〖
RV
〗
menu item, press
『
Set
』
key, the cursor moves to image area and shows “+”
mark;
2. Measure RV, the method is same as the “Distance” measurement of B general measurement;
3. The RV measured result will be shown in the display area.
13.4.5 Main Pulmonary Artery (PA)
1. Move the cursor to
〖
PA
〗
menu item, press
『
Set
』
key, the cursor moves to image area and shows “+”
mark;
2. Measure PA, the method is the same as the “Distance” measurement of B general measurement;
3. The PA measured result will be shown in the display area.
13.4.6 Calculate Cardiac Output (CO)
After measurement of LV function, it can calculate CO by keying in heart rate value.
Directly key in heart rate:
1. Move the cursor to
〖
Key In

』
key, pop up “Input Heart Rate (BPM)”dialog box in the center of screen;
2. Key in heart rate (bmp), its range is 30-180 bpm;
3. Move the cursor to choose
「
OK
」
button, press
『
Set
』
key to confirm the input value, the result will
show the value of CO; choose
「
Cancel
」
button, press
『
Set
』
key to give up keying in and exit the dialog
box.
13.4.7 Input Ejection Time (ET)
After measurements of LV function, it can calculate MVCF by keying in ET.
Directly key in ET:
1. Move the cursor to
〖
Key In
〗
menu item, pop up its submenu. Move the cursor to the
〖
ET
〗
submenu,
press
『
Set
』
key, pop up “Input Ejection Time (ms) ”dialog box in the center of screen;
2. Key in ET (ms), its range is 10-300ms;
3. Move the cursor to choose
「
OK
」
button, press
『
Set
』
key to confirm the input value, the result will
show the value of MVCF; choose
「
Cancel
」
button, press
『
Set
』
key to give up keying in and exit the
dialog box.
13.4.8 Calculate Cardiac Index, Stroke Volume Index (CI, SI)
After measurement of LV function and heart rate, it can calculate CI and SI by keying in weight, height.
