Although you can always use the standard OB calculation package, there are several ways to customize the calculation package for your specific needs. This chapter explains how to:
• Change the report and worksheet heading
• Change the configuration name
• Customize the report’s comment page
• Turn on or turn off individual measurements and calculations
• Customize equations and tables
Your changes to the OB calculations package are stored permanently (across system power-ups and new exams), until you change them again. For a complete description of OB calculation package functions, see the
User Manual.
Customizing OB
Calculations
Use OB Calc Setup to customize the OB calculation package.

To enter OB Calc Setup, press SETUP and then select OB CALC from the Setup menu.Figure 4-1 OB Calc Setup Changing the Report and
Worksheet Heading and/ or the Configuration Name
◆
To change the report and worksheet heading and/or the configuration name:1 Press SETUP and then select OB Calc from the Setup menu.
2 To change the title that displays at the top of the OB report and worksheet, enter a new title in the Header text field.
3 To change the configuration name that displays on each page of the OB report and worksheet, enter a new name in the Config Namefield.

Customizing the Comment Page
The OB worksheet contains two comment pages on which you can add additional information about the OB exam. The first comment page contains several headings for fetal anatomy and biophysical profile. During an exam, you enter comments that correspond to these headings. The second comment page is blank.
You can customize the first comment page by changing or deleting any of the headings.
◆
To customize the OB worksheet comment page:1 Click Comments in the OB Calc setup page to display the Comment Page Customization dialog box.

2 Click (turn on) each heading that you want to include on the comment page. You can change heading text by editing any of the text fields. Click again to turn off the option.
3 Turn on Free-form Comments to display the free-form
comments section. To display the free-form comments section, click
Free-form Comments. Click again to turn off the option.
4 Turn on Biophysical Profile to display the biophysical section. To display the biophysical section, click Biophysical Profile. Click again to turn off the option.
5 Click Exit to exit the setup menu, or select [PRIOR] to redisplay the OB Calc setup page.
Turning On and Off Measurements and Calculations
The OB Calc setup page has buttons next to each biometric measurement and calculated measurement. Click the corresponding button to turn on or to turn off the display of a measurement.
Table 4-1 Measurements and Calculations
Biometric Measurements The system displays the current source (author) for each biometric measurement. You can change the source using the Customize function. See “Customizing Optional Biometric Measurement Equations” on page 74.
LMP% and EFW% represent the growth percentage results.
Calculated Measurements Calculated measurements are used to determine fetal growth. The OB Calc setup page lists three of these measurements Amniotic Fluid Index (AFI), Anteroposterior Trunk Diameter (APTD), and Biparietal Diameter/Transverse Thoracic Diameter (BPD/TTD).
AFI measures the amount of amniotic fluid in the uterus. Four quadrant measurements are summed to calculate the AFI.
APTD takes a linear measurement of the fetal trunk in an anteroposterior direction.
BPD/TTD estimates the fetal weight based on the BPD/TTD
measurements. BPD/TTD is the default name for the Opt Ratio calculation. See “Adding an Optional Ratio” on page 77.
Labeled Linear Measurement (LLM)
The system provides a customizable linear measurement with a
measured value in centimeters. This measurement is not used to estimate fetal age or growth, but it can be used in equations for EFW and the customizable optional ratio. The default name for this measurement is the Anterioposterior Trunk Diameter (APTD).
◆
To rename this measurement:1 Click Customize in the OB Calc setup page and then select LLM.
2 Enter a new name for the measurement in the Result Name box. The system displays the customized name next to the measured value in the measurement menu, the OB worksheet, and the OB report.
Composite MA Calculation Choose a method for computing the composite (MA) by turning on
Hadlock composite or Arithmetic Mean.

OB Calc Equation and Table Editors
Composite Menstrual Age Calculation
Select Hadlock composite or Arithmetic Mean as a method for computing the composite Menstrual Age (MA).
If you enable Hadlock composite, the Hadlock composite equations are used for composite MA and standard deviation when the only
measurements available are any combination of BPD, HC, AC and FL. If additional measurements are available, or if you enable Arithmetic Mean, the composite MA is an arithmetic mean of the MA values for all
measurements, and no standard deviation is available.
Circumference Measurement Tool
Select Trace or Ellipse as the default measurement tool for measuring circumferences.
