When you make measurements, you can select the calculation
before you make the measurement or after you make it. If you
select the calculation before you make the measurement, the
Results Window shows the estimated fetal age as you make the
measurement. If you select the calculation after you make the
measurement, the estimated fetal age is displayed after you
complete the measurement. The measurements steps in this
section tell you to select the calculation before you make the
measurement.
The following pages describe how to make OB measurements
and calculations. The measurements are organized by mode,
and within mode are listed in alphabetical order.
Out of Range – If the system indicates that a measurement is
out of range (OOR), it means one of the following:
•
The measurement is out of the normal range based on the
gestational age that is calculated from the LMP. The system
determines OOR from the ultrasound age compared to the
gestational age. The gestational age is calculated from the
last menstrual period or the estimated delivery date.
•
The measurement is outside of the range for the data used
in the calculation. That means that the measurement is
either less than or more than the range of measurements
used to determine fetal age based on the measurement.
NOTE:
Calculation formulas are listed in the Advanced Reference
Manual.
