Cardiology 10-76 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Cardiac Worksheet After you make cardiac measurements, you can review all the data on the cardiac worksheet. To view the worksheet, select the Worksheet Display key on the Touch Panel. See Figure 10-1. The cardiac worksheet has a heading for each mode, and for each folder. In Figure 10-1, the mode heading is 2D Measurements, followed by Cube/Teichholz. Each measurement from that folder is listed next. It can list up to six values for each measurement. The next folder is then listed, in this example, RV/LV. Figure 10-1. Cardiac Worksheet: Page 1
Cardiology Measurements LOGIQ 5 Basic User Manual 10-77 Direction 2300002-100 Rev. 2 Cardiac Worksheet (continued) If a worksheet has more data on a second page, to view the next page, adjust the Page Change knob. To see page 2 and 3 of this report, see Figure 10-2 and Figure 10-3. To return to scanning, select the Worksheet Display key or press Esc. Figure 10-2. Cardiac Worksheet: Page 2
Cardiology 10-78 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Worksheet information The information on the cardiac worksheet is as follows: • Parameter – This column lists the mode, the measurement folder, and the specific measurement. • Value – The measured value. If more than one measurement was made for an item, the system uses the specified method (average, maximum, minimum, or last) to determine this value. • m1–m6 – Up to six measurement values for each item. If you make more than six measurements, the worksheet uses the last six. • Method – When there is more than one measurement for an item, this specifies the method used to calculate the measurement value listed in the Value column. Choices are average, maximum, minimum, or last. To change the method: a. Move the Trackball to the Method field. b. Press Set. c. Move the Trackball to select from the list. d. Press Set. For more information about working with worksheets, See ‘Viewing and Editing Worksheets’ for more information.

Cardiology 10-80 LOGIQ 5 Basic User Manual Direction 2300002-100 Rev. 2 Setting up and Organizing Measurements and Calculations When you receive your LOGIQ 5 system, the studies and measurements are organized for typical work flows. If you want, you can change this set up. You can change studies, create studies, and specify which measurements and calculations are in each study. You can change the measurements that are available on the Touch Panel. The LOGIQ 5 allows you to quickly and easily set up your system so that you can work most efficiently. When you make cardiac measurements, the results you see in the Results Window and the Worksheet can vary, depending on what you have set up in the Utility screens.
