Obstetrics Measurements
The following pages describe how to make OB measurements.
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.
•
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.
NOTE:
The Obstetrics measurements can be configured in

WARNING
The system provides calculations (e.g estimated fetal weight)
and charts based on published scientific literature. The
selection of the appropriate chart and clinical interpretation of
calculations and charts is the sole responsibility of the operator.
The operator must consider contraindications for the use of a
calculation or chart as described in the scientific literature. The
diagnosis, decision for further examinations and medical
treatment must be performed by qualified personnel following
good clinical practice.
